Boston’s Sign

Boston’s sign is a special eye sign seen in people with thyroid eye disease, most often in Graves’ disease. It means that when the person looks down, the upper eyelid comes down in a jerky, uneven, spasmodic way instead of moving smoothly.Moran CORE+2Ento Key+2

Boston’s sign is a movement problem of the upper eyelid. When the person looks down, the upper eyelid comes down in a jerky, uneven way instead of moving smoothly. It is usually seen in Graves’ disease and thyroid eye disease (Graves’ orbitopathy), where the tissues around the eye are swollen and tight and the eyelid muscles are overactive.Wikipedia+1

Boston’s sign itself is not a separate disease. It is a warning sign that thyroid hormones and the eye tissues are affected by an autoimmune process. Treatment focuses on controlling Graves’ disease, calming the eye inflammation, protecting the surface of the eye, and correcting eyelid position if needed. When thyroid function is stable and eye inflammation is controlled, Boston’s sign often becomes milder.MDPI+1

It is one of many classical “lid signs” of thyrotoxicosis and Graves’ ophthalmopathy (thyroid eye disease). In these conditions, the tissues and muscles around the eyes become thick, swollen and overactive because of autoimmune inflammation. This abnormal muscle action makes the eyelids move in this jerky pattern when the patient looks down.EyeWiki+2Wikipedia+2

Doctors watch for Boston’s sign during a routine eye examination in people who may have Graves’ disease or other thyroid problems, because it helps support the diagnosis of thyroid eye disease together with other signs like lid retraction (Dalrymple’s sign), lid lag (von Graefe’s sign) and bulging eyes (exophthalmos).Wikipedia+2Openmed+2

Other names (Another names) for Boston’s sign

There are no many “official” synonyms, but in textbooks and lecture notes you may see Boston’s sign described with slightly different phrases that mean the same thing, for example:

1. Boston’s eyelid sign in Graves’ disease

2. Jerky downward movement of the upper eyelid on downgaze

3. Uneven jerky motion of the upper lid in inferior gazeEnto Key+2Openmed+2

4. Jerky irregular movement of upper lid on downward gaze in thyroid eye diseaseStatPearls+1

All these phrases talk about the same clinical finding: the upper eyelid moves suddenly and unevenly when the patient moves the eyes downward, usually in the setting of Graves’ thyroid eye disease.

Types of Boston’s sign

There is only one official Boston’s sign, but in practice doctors may describe it in slightly different “types” depending on how it looks. These are not strict textbook classifications, just helpful descriptive patterns:

1. Mild Boston’s sign
   The jerky movement of the upper lid is very subtle. It may be seen only if the doctor looks carefully while the patient slowly looks down. There may be little or no eye discomfort. This often appears early in thyroid eye disease, when inflammation and muscle changes are still mild.EyeWiki+1

2. Moderate Boston’s sign
   The jerky motion of the upper lid is clearly visible to the examiner. The eyelid may pause and then suddenly drop further during downgaze. Patients often have other signs of thyroid eye disease, such as eyelid retraction, redness and mild bulging of the eyes.Wikipedia+1

3. Severe Boston’s sign
   The lid movement is very uneven and spasmodic. It may be associated with marked lid retraction, obvious exophthalmos, and restriction of eye movements due to enlarged extra-ocular muscles. In severe cases, the eye surface may dry out easily and vision may be at risk if thyroid eye disease is very active.Wikipedia+2PMC+2

4. Unilateral Boston’s sign
   Only one eye shows the jerky lid movement in downgaze. This can happen when thyroid eye disease is more active or more advanced on one side, or when another local orbital problem affects just one orbit.Wikipedia+1

5. Bilateral Boston’s sign
   Both eyes show the characteristic jerky lid movement. This is more typical in classic Graves’ eye disease, which often involves both orbits, although severity may still differ between the two sides.Wikipedia+1

---

Causes of Boston’s sign

Boston’s sign does not appear by itself. It is usually a consequence of thyroid eye disease and related changes in eyelid muscles and orbital tissues. Important causes and contributing factors include:

1. Graves’ disease (autoimmune hyperthyroidism)
   This is the most common cause. In Graves’ disease, antibodies stimulate the thyroid gland to produce too much hormone and also attack the tissues around the eyes. This causes swelling and abnormal function of the eyelid and eye muscles, leading to signs like Boston’s sign, lid lag and lid retraction.Cleveland Clinic+2American Thyroid Association+2

2. Thyroid eye disease (Graves’ ophthalmopathy / thyroid-associated orbitopathy)
   Thyroid eye disease is an autoimmune inflammation of the fat and muscles around the eye. The extra-ocular muscles and eyelid muscles become enlarged and fibrotic. This changes the way the upper lid moves and produces jerky movements in downgaze.Wikipedia+2Cleveland Clinic+2

3. High circulating thyroid hormone levels (thyrotoxicosis)
   Excess thyroid hormone increases sympathetic nervous system activity and makes muscles and nerves more excitable. This contributes to abnormal eyelid movements and lid signs, including Boston’s sign, especially when hyperthyroidism is uncontrolled.Cleveland Clinic+1

4. Autoantibodies against TSH receptor in orbital tissues
   The same antibodies that stimulate the thyroid also bind to receptors on orbital fibroblasts. These cells change into fat cells and produce glycosaminoglycans, causing swelling and scarring. The levator palpebrae and Müller’s muscle, which lift the eyelid, then move abnormally and jerkily.Wikipedia+1

5. Fibrosis of upper eyelid muscles (levator palpebrae and Müller’s muscle)
   Long-standing inflammation leads to scarring of these muscles. Scarred muscles cannot contract and relax smoothly, so when the patient looks down, the lid may hesitate and then snap down unevenly, producing Boston’s sign.Wikipedia+1

6. Exophthalmos (proptosis) from thyroid eye disease
   When the eyeball is pushed forward, the eyelids are stretched over a more protruding globe. This mechanical effect changes the dynamics of lid movement, and together with muscle changes, can produce jerky lid motion in downgaze.Wikidoc+1

7. Orbital edema and swelling of soft tissues
   In active thyroid eye disease, the tissues behind and around the eye become swollen and filled with fluid. This increases friction and resistance during eye and lid movement and can make the lid motion irregular.Wikipedia+1

8. Smoking in patients with Graves’ disease
   Cigarette smoking is a strong risk factor for more severe thyroid eye disease. It worsens inflammation and fibrosis in the orbit, so eye and lid signs, including Boston’s sign, are more likely and more severe in smokers with Graves’ disease.Wikipedia+1

9. Genetic susceptibility to autoimmune thyroid disease
   Some people carry genes that make them more likely to develop Graves’ disease and thyroid eye disease. This genetic risk increases the chance of developing eye signs such as Boston’s sign when environmental triggers appear.NCBI+1

10. Radioiodine therapy in poorly controlled Graves’ disease
    In some patients, treatment of hyperthyroidism with radioactive iodine can temporarily worsen thyroid eye disease, especially if steroids are not used and if the patient smokes. Worsening eye disease can make Boston’s sign more obvious.Wikipedia+1

11. Poor control of thyroid hormone levels (undertreated hyperthyroidism)
    If thyroid hormone levels remain high for a long time, inflammation in the orbit often stays active. This chronic activity makes lid retraction and jerky lid movements more likely to persist.Cleveland Clinic+1

12. Hashimoto’s thyroiditis with associated thyroid eye disease
    Although most thyroid eye disease occurs with Graves’ disease, similar orbital inflammation and lid signs can sometimes appear in people with Hashimoto’s thyroiditis or even normal thyroid function. In these cases, the same orbital process can still produce Boston’s sign.Wikipedia+1

13. Other autoimmune diseases affecting connective tissue
    People with generalized autoimmune tendency (for example, rheumatoid arthritis or other connective tissue diseases) may have a higher chance of developing autoimmune thyroid disease and eye involvement, indirectly leading to signs like Boston’s sign.NCBI+1

14. Orbital inflammatory diseases that mimic thyroid eye disease
    Conditions such as idiopathic orbital inflammation, sarcoidosis or other inflammatory orbitopathies can sometimes mimic thyroid eye disease and disturb eyelid muscle function, occasionally producing similar jerky lid movements, although this is less common.Wikipedia+1

15. Orbital tumors or masses causing proptosis
    A mass in the orbit can push the eye forward and distort eyelid mechanics. While classical Boston’s sign is mostly linked to Graves’ disease, any condition that alters eyelid muscle balance and orbital anatomy could theoretically produce a Boston-like jerky lid motion.Wikidoc+1

16. Previous orbital or eyelid surgery with scarring
    Surgery around the eyelids or orbit, including decompression surgery for severe thyroid eye disease, can change the tension and function of eyelid muscles, making lid movements less smooth and sometimes jerky.Wikipedia+1

17. Long-term use of high-dose corticosteroids in severe eye disease
    Steroids are often used to treat active thyroid eye disease. Over time, they can lead to changes in muscle and connective tissue structure, indirectly affecting eyelid movement and possibly exaggerating lid signs.Wikipedia+1

18. Coexisting myasthenia gravis with thyroid disease
    Myasthenia gravis, another autoimmune disease affecting neuromuscular junctions, is more common in people with autoimmune thyroid disease. It can disturb eyelid movement patterns and sometimes complicate the clinical picture of lid signs like Boston’s sign.NCBI+1

19. Systemic risk factors such as stress and viral triggers in autoimmunity
    Stressful events and some infections are thought to trigger or worsen autoimmune diseases, including Graves’ disease. When the autoimmune attack on thyroid and orbital tissues becomes more active, lid signs may appear or worsen.NCBI+1

20. Hormonal changes such as pregnancy and postpartum period in predisposed patients
    Hormonal shifts can influence immune activity and thyroid function. In some people with underlying Graves’ disease, pregnancy or the postpartum period may trigger flares of thyroid eye disease and reveal signs such as Boston’s sign.NCBI+1

Symptoms linked with Boston’s sign

Boston’s sign itself is a sign seen by the doctor, not something every patient notices. However it usually appears together with symptoms of thyroid eye disease and hyperthyroidism:

1. Feeling that the eyes are bulging or “staring”
   Because the eyeballs may protrude (exophthalmos) and the eyelids are retracted, patients often feel that their eyes look wide and staring. Other people may notice this change first.Wikipedia+2Cleveland Clinic+2

2. Eye dryness and gritty sensation
   With bulging eyes and widened palpebral fissure, the cornea is exposed to air for longer. Tears evaporate quickly, causing dryness and a sandy or gritty feeling, which is very common in thyroid eye disease.Wikipedia+2Cleveland Clinic+2

3. Redness of the eyes and eyelids
   Inflammation of the conjunctiva and eyelids leads to redness, swelling and irritation. The eyes may look bloodshot, especially when the disease is active.Cleveland Clinic+2PMC+2

4. Excessive tearing or watering of the eyes
   The eyes try to compensate for dryness and irritation by making more tears. At the same time, the tear drainage system may not work well because the lids are misshapen, so tears may run down the cheeks.Cleveland Clinic+1

5. Burning, stinging or foreign-body sensation
   Dryness, exposure and small surface erosions on the cornea and conjunctiva cause a burning or stinging feeling, like something is in the eye. This can become worse in wind or air-conditioned rooms.PMC+1

6. Light sensitivity (photophobia)
   An irritated cornea and inflamed ocular surface are more sensitive to light. Patients may prefer sunglasses even on not-too-bright days and may squint or close their eyes in strong light.Cleveland Clinic+1

7. Eye pain or pressure sensation behind the eyes
   Swollen muscles and tissues inside the orbit increase pressure in the confined bony space. Patients may feel dull aching or a pressure sensation behind the eyes, especially when moving the eyes.Wikipedia+2PMC+2

8. Headache around the eye or forehead
   Constant eye strain, dry eyes and orbital pressure can lead to headache, especially around the forehead and brow area.Cleveland Clinic+1

9. Double vision (diplopia)
   When the extra-ocular muscles become enlarged and stiff, the eyes may not move together smoothly. This can cause double vision, especially when looking up or to the side. This is an important symptom of more advanced disease.Cleveland Clinic+2Wikipedia+2

10. Difficulty moving the eyes in certain directions
    Fibrosis and swelling of the eye muscles can limit eye movements. Patients may notice that one eye does not move as far up, down, in or out as the other eye.Wikipedia+1

11. Feeling of “tired eyes” or eye fatigue
    Prolonged eye strain from trying to keep the eyes comfortable and aligned can cause a feeling of fatigue. Patients often report that reading or screen use becomes difficult.Cleveland Clinic+1

12. Blurry vision that comes and goes
    Dryness and surface irregularities on the cornea can make vision fluctuate. Blurriness may improve after blinking or using artificial tears, which is typical in thyroid eye disease.Cleveland Clinic+2Wikipedia+2

13. Decreased vision in severe cases
    If swelling compresses the optic nerve at the back of the orbit, or if the cornea becomes badly damaged, vision can drop and may not fully recover. This is a serious complication and needs urgent care.Wikipedia+1

14. General symptoms of hyperthyroidism
    Because Boston’s sign usually appears in the setting of Graves’ disease, patients may also have weight loss, heat intolerance, tremor, palpitations, anxiety and trouble sleeping.Cleveland Clinic+2Mayo Clinic+2

15. Cosmetic and psychological distress
    Changes in appearance, such as staring look, eyelid changes and bulging eyes, can affect self-confidence and mood. Some patients with thyroid eye disease feel depressed, anxious or socially withdrawn because of the way their eyes look.Wikipedia+1

 

Diagnostic Tests

Physical examination tests for Boston’s sign and related problems

1. General eye and face inspection
   The doctor first looks at the face and eyes in normal straight-ahead gaze. They note any bulging of the eyes, eyelid retraction, swelling, redness, asymmetry or facial changes. This simple visual inspection already gives strong clues about thyroid eye disease.Wikidoc+1

2. Dynamic downgaze test for Boston’s sign
   To check for Boston’s sign, the patient is asked to follow a target (like the examiner’s finger) slowly from looking straight ahead downwards. The doctor watches the upper eyelid carefully. In Boston’s sign, the lid does not glide smoothly; instead it moves in a jerky, irregular way as the eye moves down.Moran CORE+2Ento Key+2

3. Palpebral fissure and scleral show assessment
   The distance between upper and lower eyelids (palpebral fissure) and the amount of white sclera visible above or below the cornea are observed. Widening of this gap and exposure of sclera suggest lid retraction (Dalrymple’s sign) and lid lag signs, which commonly accompany Boston’s sign in Graves’ disease.Wikipedia+2Wikipedia+2

4. Exophthalmometry (Hertel measurement)
   Using a special instrument called an exophthalmometer, the examiner measures how far each eye protrudes from the orbit. Values greater than normal, or big differences between the two sides, confirm exophthalmos, which is closely linked to thyroid eye disease and many eyelid signs.Wikidoc+1

---

Manual bedside tests

5. Ocular motility and alignment test
   The doctor asks the patient to follow a target in all directions of gaze and watches how the eyes move together. Limited movement, especially in upgaze or lateral gaze, suggests involvement of the extra-ocular muscles in thyroid eye disease and helps explain symptoms like double vision.Wikipedia+2PMC+2

6. Blink rate and completeness observation
   The examiner observes how often and how completely the patient blinks. In Graves’ disease, blinking can be infrequent and incomplete (Stellwag’s sign), which combines with lid retraction and Boston’s sign to dry out the eye surface.Wikipedia+2Openmed+2

7. Lid traction and resistance test (Grove-type check)
   The examiner gently pulls the upper lid downward and notes how much resistance there is. In thyroid eye disease, the upper lid may resist downward traction due to scarring and overaction of the muscles, and this abnormal tension is related to jerky lid movements like Boston’s sign.Moran CORE+2Openmed+2

8. Confrontation visual field test
   The doctor tests peripheral vision by bringing fingers in from the sides while the patient looks straight ahead. This bedside test can pick up field defects caused by optic nerve compression or other orbital complications of severe thyroid eye disease.Wikipedia+1

---

Laboratory and pathological tests

9. Serum thyroid-stimulating hormone (TSH)
   TSH is the main screening blood test for thyroid function. In Graves’ disease, TSH is usually very low because the pituitary gland senses high thyroid hormone levels. An abnormal TSH supports the diagnosis of hyperthyroidism in a patient with Boston’s sign.Cleveland Clinic+2American Thyroid Association+2

10. Free thyroxine (Free T4) and triiodothyronine (T3)
    These tests measure the actual thyroid hormones in the blood. In Graves’ disease, Free T4 and/or T3 are typically elevated. Raised thyroid hormones together with eye signs like Boston’s sign confirm that the eyelid changes are likely related to thyrotoxicosis.Cleveland Clinic+2American Thyroid Association+2

11. TSH receptor antibodies (TRAb) / thyroid-stimulating immunoglobulins
    These autoimmune antibodies are a hallmark of Graves’ disease. A positive TRAb test strongly supports autoimmune thyroid disease and helps link Boston’s sign to this specific cause.American Thyroid Association+2NCBI+2

12. Anti-thyroid peroxidase (TPO) and anti-thyroglobulin antibodies
    These antibodies show autoimmune attack on thyroid tissue. They are more typical of Hashimoto’s thyroiditis but may also be present in Graves’ disease and related autoimmune thyroid disorders that can coexist with thyroid eye disease.NCBI+1

13. Basic blood tests and inflammatory markers (CBC, ESR, CRP)
    A complete blood count and markers like ESR or CRP can show general inflammation or help detect other diseases that might mimic thyroid eye disease, such as systemic inflammatory or infectious conditions affecting the orbit.NCBI+2Wikipedia+2

---

Electrodiagnostic tests

14. Visual evoked potentials (VEP)
    VEP measures the brain’s electrical response to visual stimuli. It helps assess the function of the optic nerve. In severe orbital disease with possible optic nerve compression, VEP can detect delayed or reduced responses even before major vision loss occurs.Wikipedia+1

15. Electromyography (EMG) of extra-ocular and eyelid muscles
    EMG records electrical activity in muscles. It can be used to study how the eyelid and eye muscles fire in thyroid eye disease and to distinguish muscle problems from nerve disorders like myasthenia gravis, which can also affect eyelid movement.NCBI+2Wikipedia+2

16. Nerve conduction studies and EMG for associated neuropathies
    These tests examine the health of peripheral nerves and muscles. They are useful when the doctor suspects another neuromuscular disease alongside thyroid eye disease, for example in patients with unusual or asymmetric lid and eye movement problems.NCBI+1

---

Imaging tests

17. Orbital ultrasound
    Ultrasound of the orbit uses sound waves to image the eye muscles and tissues. It can show thickening of the extra-ocular muscles and increased orbital tissue volume in thyroid eye disease. It is non-invasive, quick and helpful for confirming muscular involvement.Wikipedia+1

18. CT (computed tomography) scan of the orbits
    CT provides detailed images of bone and soft tissues in the orbit. In Graves’ orbitopathy it typically shows enlarged extra-ocular muscles with sparing of their tendons and increased orbital fat. CT also helps detect optic nerve compression and guides surgical planning if needed.Wikipedia+1

19. MRI (magnetic resonance imaging) of the orbits and brain
    MRI gives excellent detail of soft tissues and nerves. It can show the degree of muscle inflammation, edema and fibrosis, and helps distinguish thyroid eye disease from other causes of orbital inflammation or tumors. It is especially useful when optic nerve involvement is suspected.Wikipedia+1

20. Radioactive iodine uptake test and thyroid scan
    This nuclear medicine test shows how actively the thyroid gland takes up iodine. In Graves’ disease, uptake is usually high and diffuse. The scan helps confirm the type of hyperthyroidism causing the eye signs, including Boston’s sign, and guides treatment decisions such as radioiodine therapy or surgery.Cleveland Clinic+2American Thyroid Association+2

Non-Pharmacological Treatments

1. Smoking cessation
   Stopping smoking is one of the most powerful non-drug treatments for Boston’s sign because smoking strongly worsens thyroid eye disease. Quitting reduces inflammation in the eye tissues, improves blood flow, and may lower the risk of eye disease becoming severe or needing big doses of steroids or surgery. Counseling, nicotine-free coping strategies, and support groups help people stop smoking and stay smoke-free in the long term.Acta Medica Indonesiana+1

2. Tight control of thyroid hormone with regular follow-up
   Regular visits with an endocrinologist, frequent thyroid blood tests, and careful adjustment of treatment help keep thyroid hormone levels in the normal range. Stable thyroid levels lower the autoimmune activity that drives eyelid retraction and Boston’s sign. The mechanism is simple: fewer thyroid-stimulating antibodies and stable hormone levels lead to less stimulation of the eye muscles and tissues.etj.bioscientifica.com+1

3. Eye lubrication with artificial tears (supportive measure)
   Preservative-free artificial tears used several times a day keep the front of the eye moist when the eyelids are pulled back and the eyes are more open than normal. This reduces dryness, burning, and foreign-body sensation and helps prevent damage to the cornea. The drops work by forming a protective tear film layer that replaces the natural tears that evaporate quickly in eyelid retraction.EyeWiki+1

4. Lubricating ointment at night
   A thicker eye ointment used before sleep protects the eye surface overnight when the eyelids may not close fully. The ointment stays longer on the eye than drops, forming a greasy shield that prevents the cornea from drying and getting scratched. This is especially helpful in people with marked eyelid retraction and lagophthalmos, who wake with pain, redness, and blurred vision.PMC+1

5. Sleeping with head elevated
   Raising the head of the bed or using extra pillows reduces fluid congestion around the eyes. Less fluid means less puffiness of the eyelids and surrounding tissues in the morning. The mechanism is gravity: elevation improves venous and lymphatic drainage from the orbit, which can relieve pressure and slightly reduce eyelid retraction and eye bulging on waking.PMC+1

6. Cool compresses
   Gently applied cool compresses over closed eyelids can reduce redness, warmth, and swelling during active phases of thyroid eye disease. Cooling causes blood vessels to narrow and reduces leakage of fluid into the tissues. This simple home therapy can temporarily ease discomfort, burning, and the feeling of pressure behind the eyes linked to Boston’s sign.PMC+1

7. Sunglasses and wind protection
   Large wrap-around sunglasses protect the eyes from wind, dust, and bright light. Because eyelid retraction increases the exposed surface of the eye, patients with Boston’s sign are more sensitive to sunlight, dry air, and tiny particles. Sunglasses work as a physical shield, lowering irritation, reflex tearing, and squinting, and they also help with cosmetic concerns in public.EyeWiki+1

8. Moisture chamber glasses
   Moisture chamber goggles or glasses have a soft seal around the eyes to trap humidity. They are useful in people with severe exposure where ordinary tears and drops are not enough. By keeping a humid micro-environment around the eye, they reduce evaporation of tears and protect the cornea, lowering pain and the risk of exposure keratopathy that can occur with marked eyelid retraction.EyeWiki+1

9. Blinking and eyelid stretching exercises
   Gentle, frequent blinking and guided exercises that encourage full eyelid closure can help some patients with mild retraction. These exercises train the eyelid muscles to relax and move through a full range of motion. While they cannot reverse structural changes, they may reduce eye dryness and improve comfort by spreading tears more evenly over the cornea.PMC+1

10. Prism glasses for double vision
    When thyroid eye disease causes double vision together with Boston’s sign, special prisms added to glasses can help images line up better. The prisms bend light so that both eyes see a single image even when the eye muscles are misaligned. This does not change eyelid position but improves daily function, stability while walking, and reading comfort.ScienceOpen+1

11. Eye patching in severe double vision
    In people with disabling double vision that is not yet ready for surgery, covering one eye with a patch or opaque contact lens can give immediate relief. The brain then receives a single image, reducing dizziness and nausea. This is usually a short-term supportive method while inflammation settles or while planning more definitive treatment.ScienceOpen+1

12. Humidifier use at home and work
    Using a room humidifier adds moisture to the air, especially in air-conditioned or heated rooms that are very dry. For a person with eyelid retraction and exposed eyes, higher humidity means slower tear evaporation and less dryness and burning. This environmental change is easy, safe, and can significantly improve daily comfort.PMC+1

13. Avoiding irritants (wind, dust, harsh chemicals)
    People with Boston’s sign should avoid direct exposure to strong wind, dust, smoke, and chemical fumes. These irritants quickly dry and inflame the exposed eye surface. Simple steps such as turning away from fans, using protective glasses at work, and avoiding smoky environments can reduce eye redness and the risk of corneal damage.PMC+1

14. Stress management and mental health support
    Chronic autoimmune diseases like Graves’ disease can cause anxiety, body-image worries, and low mood. Stress hormones may also worsen immune activity. Relaxation techniques, counseling, and support groups help patients cope emotionally with changes in eye appearance and vision, improve adherence to treatment, and support overall health.MDPI+1

15. Healthy sleep routine
    Good sleep habits—regular bedtimes, quiet dark room, and avoiding screens late at night—support immune balance and hormone regulation. Poor sleep can increase inflammation and make eye discomfort feel worse. A stable sleep pattern, combined with head elevation, can reduce morning eyelid swelling and improve comfort in people with Boston’s sign.MDPI+1

16. Regular exercise within medical advice
    Moderate physical activity helps control weight, improves circulation, and supports mental health. Exercise may indirectly benefit thyroid eye disease by improving overall health and reducing cardiovascular risks associated with thyroid problems. Patients should choose low-impact activities and follow advice from their doctor if they have heart issues or severe hyperthyroidism.etj.bioscientifica.com+1

17. Iodine and medication safety education
    Patients are taught to avoid unnecessary high-iodine exposure, to tell doctors they have Graves’ disease, and to check before using certain contrast dyes or over-the-counter supplements. This reduces the risk of sudden thyroid hormone swings that can flare eye disease. Education also helps patients recognize early eye symptoms and seek care promptly.etj.bioscientifica.com+1

18. Workplace and driving adaptations
    Adjusting screen height, font size, lighting, and taking frequent breaks reduces strain on dry, exposed eyes. For driving, anti-glare lenses and avoiding night driving during active disease can improve safety. These practical changes decrease eye fatigue and help patients remain independent while Boston’s sign and other eye features are being treated.Brigham and Women’s Hospital+1

19. Protective eyewear for sports and risky tasks
    In sports or jobs where flying particles or injuries are possible, tight-fitting safety goggles are important. Because eyelid retraction leaves more of the eye exposed, even a small injury can cause serious damage. Protective eyewear acts as a shield, lowering the chance of corneal scratches or trauma.PMC+1

20. Patient education about Boston’s sign and thyroid eye disease
    Clear explanations about what Boston’s sign means, how autoimmune thyroid disease affects the eyes, and what treatments are available help patients feel less afraid and more in control. Education improves adherence to medicines, follow-up visits, and lifestyle changes, and helps patients notice red-flag symptoms early, which can protect sight.etj.bioscientifica.com+1

Drug Treatments

Important: Drug treatment for Graves’ disease and thyroid eye disease must always be guided by an endocrinologist and eye specialist. Doses and timing depend on age, weight, other illnesses, and lab results, especially in teenagers. Never start, stop, or change these medicines without medical advice.

1. Methimazole (thioamide antithyroid drug)
   Methimazole is the main medicine used to reduce overactive thyroid hormone production in Graves’ disease. It blocks key steps in thyroid hormone synthesis in the gland.FDA Access Data+2FDA Access Data+2 It is usually taken once or several times per day by mouth, with the exact dose and schedule set using the FDA label and blood tests. Common side effects include rash, itching, joint pain, and rare but serious low white blood cell counts or liver problems. By calming hyperthyroidism, it reduces the autoimmune drive that worsens thyroid eye disease and Boston’s sign.

2. Propylthiouracil (PTU, antithyroid drug)
   Propylthiouracil also blocks thyroid hormone synthesis and partly blocks the conversion of T4 to T3 in the body. It is used when methimazole is not suitable, such as early pregnancy or certain reactions.FDA Access Data+1 It is given in divided daily doses and closely monitored with liver and blood tests. Major risks include liver injury and low white blood cells. By controlling thyroid hormone levels, PTU can indirectly help stabilize eye signs, including Boston’s sign.

3. Beta-blockers (for symptom control, e.g., propranolol)
   Beta-blockers do not treat the autoimmune disease itself, but they control symptoms of hyperthyroidism such as fast heartbeat, tremor, and anxiety.FDA Access Data+1 They are usually taken by mouth once or several times daily. Side effects can include tiredness, low heart rate, or worsening asthma. Better heart control and reduced stress may help patients feel more comfortable while other treatments work on the underlying Graves’ disease.

4. Systemic glucocorticoids – intravenous methylprednisolone
   High-dose intravenous methylprednisolone is a standard first-line treatment for active, moderate-to-severe thyroid eye disease.PMC+1 It strongly reduces inflammation around the eye, lowers swelling of muscles and fat, and can improve eyelid retraction and pain. Treatment is given in pulses over several weeks in hospital or specialist clinics. Side effects include weight gain, high blood pressure, mood changes, high blood sugar, and risk of infections, so strict monitoring is needed.

5. Systemic glucocorticoids – oral prednisone
   Oral prednisone may be used alone in milder cases or as a step-down after intravenous steroids.endocrinologia.org.mx+1 It is taken once daily with food, and the dose is slowly reduced according to response and side effects. Prednisone suppresses immune activity and reduces orbital inflammation, but side effects such as bone thinning, blood sugar changes, and mood shifts limit long-term use.

6. Teprotumumab (TEPEZZA, anti-IGF-1 receptor monoclonal antibody)
   Teprotumumab is an FDA-approved biologic drug specifically for thyroid eye disease.FDA Access Data+2FDA Access Data+2 It is given as weight-based intravenous infusions every three weeks for a total of eight doses in a specialized clinic. It works by blocking the insulin-like growth factor-1 receptor on orbital cells, reducing inflammation, tissue expansion, and proptosis. Clinical studies show meaningful reductions in eye bulging and improvement in eye symptoms, though side effects like muscle spasms, hearing changes, and high blood sugar can occur.Veterans Affairs+1

7. Mycophenolate mofetil (immunosuppressant)
   Mycophenolate is sometimes used together with intravenous steroids as recommended by European guidelines for active moderate-to-severe Graves’ orbitopathy.endocrinologia.org.mx+1 It is taken by mouth twice daily under careful blood monitoring. The drug reduces lymphocyte activity, lowering autoimmune attack on orbital tissues. Common side effects include stomach upset, low blood counts, and increased infection risk.

8. Cyclosporine (calcineurin inhibitor)
   Cyclosporine is an older systemic immunosuppressant that has been used in combination with steroids in selected thyroid eye disease cases.MDPI+1 It reduces T-cell activation. It is given by mouth with regular checks of kidney function and drug levels. Side effects include high blood pressure, kidney damage, and gum swelling. Because of toxicity, it is reserved for difficult cases in expert centers.

9. Rituximab (anti-CD20 monoclonal antibody)
   Rituximab targets B cells that make antibodies involved in Graves’ orbitopathy. It is given as intravenous infusions under specialist supervision. Randomized trials show mixed results, with some benefit and some studies showing no clear advantage over placebo, but it is still used in selected steroid-resistant cases.Mayo Clinic+3PubMed+3PMC+3 Side effects can include infusion reactions and infection risk.

10. Tocilizumab (IL-6 receptor monoclonal antibody)
    Tocilizumab blocks the interleukin-6 receptor, dampening inflammatory signaling. Observational studies and small trials suggest it can improve clinical activity scores and reduce inflammation in steroid-resistant moderate-to-severe Graves’ orbitopathy.PubMed+3EyeWiki+3PMC+3 It is given as intravenous infusions at intervals. Side effects include infections, liver enzyme changes, and cholesterol rise.

11. Topical artificial tears (ophthalmic lubricants)
    Although classed as medical devices or OTC products rather than systemic drugs, artificial tear eye drops are a cornerstone of treatment. They are used many times per day to replace or supplement natural tears and reduce friction on the cornea.EyeWiki+1 Usually preservative-free formulations are chosen for frequent use to avoid extra irritation.

12. Lubricating eye ointments
    Night-time ointments keep the cornea coated for several hours, particularly helpful when eyelids do not close fully due to retraction.PMC+1 They are usually applied inside the lower fornix at bedtime. Blurred vision after use is expected, so they are mainly used overnight.

13. Topical cyclosporine eye drops for dry eye
    In selected patients, cyclosporine-based eye drops can help chronic surface inflammation and tear film instability. They suppress local T-cell-mediated inflammation on the ocular surface, improving symptoms of dryness and redness over time. This does not directly change Boston’s sign but may improve comfort and corneal health.EyeWiki+1

14. Non-steroidal anti-inflammatory drugs (NSAIDs) for pain
    Short-term use of NSAIDs such as ibuprofen may be recommended by doctors to relieve pain and headache linked to eye strain and inflammation. They work by blocking cyclo-oxygenase enzymes and reducing prostaglandin production. Side effects include stomach irritation and, with heavy use, kidney and cardiovascular risks, so they must be used carefully, especially with steroids.Cleveland Clinic+1

15. Proton pump inhibitors (PPIs) for stomach protection
    When high-dose steroids are needed, PPIs such as omeprazole may be prescribed to protect the stomach lining from ulcers and bleeding. They reduce acid production in the stomach. This supportive treatment does not affect Boston’s sign directly but allows safer use of steroid therapy.PMC+1

16. Topical antibiotic drops or ointment (for exposure-related corneal damage)
    If eyelid retraction and exposure lead to corneal erosions or ulcers, antibiotic drops or ointments may be used to prevent or treat infection. They are usually applied several times daily for a limited period. This protects the healing cornea but must be combined with lubrication and sometimes bandage lenses or surgery.PMC+1

17. Radioactive iodine (RAI) – systemic thyroid ablation
    RAI is a targeted form of radiation that destroys overactive thyroid tissue and is a standard treatment for Graves’ hyperthyroidism.etj.bioscientifica.com+1 However, it can sometimes worsen thyroid eye disease, especially in smokers, so guidelines recommend careful selection, steroid prophylaxis in high-risk patients, or surgery as an alternative. The decision requires specialist evaluation.

18. Levothyroxine replacement after thyroid ablation or surgery
    After total thyroid ablation or removal, levothyroxine tablets replace missing thyroid hormone. Keeping levels stable (euthyroid) is important because both over- and under-treatment can affect eye disease.etj.bioscientifica.com+1 Doses are individualized based on weight and blood tests.

19. Tamsulosin (experimental for eyelid retraction)
    Recent research suggests that tamsulosin, an alpha-1 blocker commonly used for prostate enlargement, might temporarily improve eyelid retraction in thyroid eye disease by relaxing Müller’s muscle in the eyelid.Nature+1 This use is still experimental and must only be considered under specialist supervision, with careful monitoring for blood pressure changes.

20. Biologic combinations and future targeted agents
    Newer monoclonal antibodies and targeted agents are being studied to modulate specific immune pathways in Graves’ orbitopathy, including combinations of anti-CD20, anti-IL-6, and anti-IGF-1R drugs.Frontiers+1 These therapies aim to reduce inflammation, tissue expansion, and fibrosis more precisely, with fewer side effects than broad steroids. At present they are mainly available in research settings or specialized centers.

Dietary Molecular Supplements

Note: Supplements can interact with medicines. In teenagers and adults, any regular supplement use should be discussed with a doctor or dietitian.

1. Selenium
   Selenium is a trace mineral that plays an important role in antioxidant defense and thyroid hormone metabolism. A randomized trial found that a 6-month selenium course in mild Graves’ orbitopathy improved eye quality-of-life scores and slowed disease progression.Jwatch+1 Typical doses follow guideline or product recommendations; too much selenium can be toxic. Selenium helps by reducing oxidative stress in orbital tissues and modulating immune responses.

2. Omega-3 fatty acids (fish oil or algae oil)
   Omega-3 fatty acids such as EPA and DHA have anti-inflammatory effects and may help dry eye and surface inflammation. They are usually taken in standard capsule doses with meals. They reduce production of pro-inflammatory eicosanoids and support tear film quality. People on blood-thinning medicines need medical advice before using high-dose omega-3 supplements.PMC+1

3. Vitamin D
   Vitamin D supports immune balance, bone health (important during steroid therapy), and muscle function. Many people with autoimmune diseases have low levels. Supplement doses are based on blood tests and national guidelines. Vitamin D acts through nuclear receptors to modulate T-cell and B-cell responses and may indirectly support control of Graves’ disease and eye inflammation.MDPI+1

4. Vitamin C
   Vitamin C is a water-soluble antioxidant that protects tissues from oxidative stress. Supplementation within safe daily limits can support general immune function and collagen health. For thyroid eye disease, it may help limit oxidative damage to orbital tissues and support healing of the ocular surface, though direct clinical trial data are limited.MDPI+1

5. Vitamin E
   Vitamin E is a fat-soluble antioxidant that protects cell membranes from oxidative damage. In combination with other antioxidants, it may help reduce chronic inflammation and protect delicate tissues in the eye. Doses must stay within safe ranges to avoid bleeding risks, especially if the patient uses anticoagulants.MDPI+1

6. Zinc
   Zinc is important for immune function and wound healing and is present in many enzymes. Moderate supplementation, when needed, supports normal immune regulation and maintains healthy epithelial tissues, including the ocular surface. Excess zinc can interfere with copper balance, so dosing should follow medical or dietitian guidance.MDPI+1

7. B-complex vitamins
   B vitamins support energy metabolism and nervous system function. In Graves’ disease, good nutritional status helps the body cope with hypermetabolism and stress. B-complex supplements usually contain B1, B2, B6, B12, and folate at standard doses. They may help reduce tiredness and support nerve health, indirectly improving quality of life in people with thyroid eye disease.MDPI+1

8. Coenzyme Q10
   Coenzyme Q10 is involved in mitochondrial energy production and acts as an antioxidant. Supplements may help reduce fatigue and oxidative stress. In theory, better mitochondrial function and antioxidant support could help tissues under chronic autoimmune attack, although specific trials in Graves’ orbitopathy are limited.PMC+1

9. L-carnitine
   L-carnitine helps transport fatty acids into mitochondria for energy production. Some studies have explored its use in hyperthyroidism-related muscle weakness and fatigue. It may counteract certain metabolic effects of excess thyroid hormone by improving muscle energy handling, though data are not specific to Boston’s sign.MDPI+1

10. Curcumin (from turmeric)
    Curcumin has anti-inflammatory and antioxidant properties. In many inflammatory conditions it can reduce signaling through NF-κB and other pathways. As a supplement, it is usually taken with food and often combined with ingredients that improve absorption. Evidence specific to thyroid eye disease is still emerging, so curcumin is considered an adjunct, not a main therapy.Frontiers+1

Immunity-Modulating and Regenerative / Stem Cell–Related Approaches

1. Teprotumumab as a disease-modifying biologic
   Teprotumumab is a fully human monoclonal antibody that targets the IGF-1 receptor, which is over-expressed in orbital fibroblasts and helps drive inflammation and tissue expansion.FDA Access Data+1 By blocking this receptor, it reduces signaling that causes extra fat and muscle growth behind the eye. This makes it a true disease-modifying therapy for Graves’ orbitopathy rather than just symptom control.

2. Rituximab for B-cell modulation
   Rituximab targets CD20 on B lymphocytes, which produce autoantibodies against thyroid-related antigens. In thyroid eye disease, it can reduce B-cell counts and autoantibody production, potentially calming orbital inflammation. Trials have shown mixed results but it remains a possible option in carefully selected, resistant cases, always under close specialist supervision.ACCP Journals+3PubMed+3PMC+3

3. Tocilizumab for steroid-resistant disease
   Tocilizumab blocks the IL-6 receptor, reducing a key inflammatory pathway active in Graves’ orbitopathy. Studies show improvements in clinical activity scores in patients with steroid-resistant disease.American Thyroid Association+3PMC+3Frontiers+3 This approach is considered when standard steroid therapy fails or cannot be tolerated.

4. Intravenous immunoglobulin (IVIG)
   IVIG consists of pooled antibodies from healthy donors and is sometimes used as an immunomodulatory therapy in complex autoimmune diseases. It may alter immune responses, neutralize autoantibodies, and regulate complement. Evidence in Graves’ orbitopathy is limited, and treatment is costly, so it is reserved for special situations in expert centers.Frontiers+1

5. Mesenchymal stem cell research
   Experimental studies show that human placenta-derived mesenchymal stem cells can reduce adipogenesis (fat cell formation) in models of Graves’ orbitopathy and modulate immune responses.PMC+3PMC+3SpringerLink+3 These cells may act by secreting anti-inflammatory factors and altering fibroblast behavior. At present, stem cell therapy is research-only and not standard care.

6. Future regenerative eye therapies
   Research into orbital stem cells and tissue engineering aims to repair or remodel damaged tissues around the eye. Future therapies might combine biologic drugs with cell-based treatments to reverse fibrosis and abnormal fat expansion.IOVS+2ScienceDirect+2 These ideas are still in early development and are not yet available in routine clinical practice.

Surgical Treatments

1. Orbital decompression surgery
   Orbital decompression removes parts of the bony orbital walls and/or orbital fat to create more space for swollen tissues and allow the eye to move back into a safer position.Aetna+3PMC+3EyeWiki+3 It is done when there is sight-threatening optic nerve compression, severe corneal exposure, or disfiguring proptosis. The aim is to reduce pressure, protect vision, and improve appearance.

2. Strabismus (squint) surgery
   When thyroid eye disease causes permanent eye muscle scarring and misalignment leading to double vision, squint surgery can reposition and adjust affected muscles.SpringerLink+1 After the disease becomes inactive, surgeons lengthen or shorten certain muscles to improve alignment and reduce double vision in everyday gaze positions. This indirectly reduces the strain that can worsen discomfort associated with Boston’s sign.

3. Eyelid retraction surgery
   Specific eyelid procedures can lower an overly high upper lid or raise a pulled-down lower lid. Techniques include recession of Müller’s muscle and the levator aponeurosis, use of spacer grafts, or full-thickness blepharotomy.thyroideyedisease.com.au+3PMC+3EyeWiki+3 These operations aim to restore a more normal eyelid position, reduce eye exposure, and improve comfort and appearance in patients with Boston’s sign.

4. Tarsorrhaphy and temporary eyelid closure procedures
   In severe exposure keratopathy where the cornea is at risk, surgeons may partially sew the eyelids together (tarsorrhaphy) to protect the eye. This can be temporary or permanent depending on the situation. By reducing the palpebral opening, the cornea is shielded from drying and injury while other treatments, such as decompression or biologics, take effect.Dove Medical Press+1

5. Thyroidectomy (surgical removal of the thyroid)
   Total or near-total thyroidectomy is a definitive treatment for Graves’ hyperthyroidism. It quickly removes the source of excessive hormone and may be preferred in patients with active or severe eye disease, especially when radioactive iodine is considered risky.etj.bioscientifica.com+1 After surgery, stable hormone replacement can help reduce fluctuations that might worsen eye problems, including Boston’s sign.

When to See a Doctor

Anyone with Boston’s sign or other signs of thyroid eye disease should see an endocrinologist and an eye specialist (ideally a neuro-ophthalmologist or oculoplastic surgeon). An early assessment helps set a baseline and plan for monitoring.Brigham and Women’s Hospital+1

Seek urgent medical help if there is sudden vision loss, blurred or dim vision, pain with eye movement, color vision changes, severe eye redness and swelling, or if you cannot close your eyelids fully. These can be signs of optic nerve compression or severe corneal exposure, which can threaten sight.PMC+1

Regular visits are also needed if you are starting or changing antithyroid drugs, steroids, or biologic therapies, or if you are planning surgery. For teenagers, it is especially important that parents or guardians attend visits and help with safe medicine use.

What to Eat and What to Avoid

1. Eat a balanced diet rich in fruits, vegetables, whole grains, and lean protein to support healing and immune balance; avoid highly processed fast foods that add salt, sugar, and unhealthy fats.MDPI+1

2. Eat foods with natural selenium (such as small amounts of fish, eggs, and whole grains) if appropriate; avoid taking high-dose selenium supplements without medical advice, as they can be toxic.Jwatch+1

3. Eat oily fish or plant sources of omega-3s regularly; avoid very high doses of omega-3 capsules unless recommended by a doctor, especially if you take blood thinners.PMC+1

4. Eat calcium- and vitamin-D-rich foods (like dairy or fortified alternatives) if you are on steroids to protect bone health; avoid very high-salt foods that can worsen blood pressure and swelling.endocrinologia.org.mx+1

5. Eat plenty of fiber from vegetables, fruits, and whole grains; avoid too much caffeine and energy drinks, which can worsen palpitations and anxiety in hyperthyroidism.Cleveland Clinic+1

6. Drink enough water to stay well hydrated; avoid sugary soft drinks and very sweet juices that add calories and may worsen blood sugar control, especially with steroid use.endocrinologia.org.mx+1

7. Eat foods rich in antioxidants (berries, leafy greens, colorful vegetables); avoid heavy alcohol use, which can interact with medicines and harm liver function.MDPI+1

8. Use iodine-containing foods (such as iodized salt) in normal amounts if your doctor approves; avoid sudden large changes in iodine intake (for example, large kelp supplements) that might disturb thyroid control.etj.bioscientifica.com+1

9. Eat small, regular meals if hyperthyroidism makes you hungry and shaky; avoid fasting or crash diets that stress the body and make it harder to stabilize thyroid levels.etj.bioscientifica.com+1

10. Follow any individualized diet plan set by your endocrinologist or dietitian; avoid internet “miracle diets” that claim to cure thyroid or eye disease without solid scientific evidence.MDPI+1

Frequently Asked Questions

1. Is Boston’s sign itself dangerous?
   Boston’s sign is mainly a signal that thyroid eye disease is present, not a separate dangerous disease. However, it means that the eyelids and eye muscles are affected by autoimmune activity. Ignoring it can allow more serious problems, like corneal damage or optic nerve compression, to develop. Early assessment helps keep you safe.Wikipedia+1

2. Can Boston’s sign go away on its own?
   In some people, mild eyelid signs improve when thyroid hormone levels are corrected and eye inflammation settles. Others may have persistent retraction that needs drops, biologic treatment, or eyelid surgery. The course is very individual and depends on how active the autoimmune process is and how quickly treatment begins.etj.bioscientifica.com+1

3. Does everyone with Graves’ disease develop Boston’s sign?
   No. Many people with Graves’ disease never develop obvious eyelid movement problems. Others may show eyelid retraction or lag but not the classic jerky movement of Boston’s sign. Eye involvement can range from almost invisible to very severe, even within the same family.MDPI+1

4. Is Boston’s sign common in children or teenagers?
   Graves’ disease and thyroid eye disease can occur in young people, although they are more common in adults. When they do occur in children or teenagers, careful monitoring is essential because eyes and facial structures are still developing. Any eyelid retraction or unusual eye movements should be evaluated by a pediatric endocrinologist and eye specialist.MDPI+1

5. Can glasses alone fix Boston’s sign?
   Ordinary glasses cannot change eyelid movement, but they can correct vision problems. Special prisms can help with double vision caused by eye muscle involvement. However, to address Boston’s sign itself, you usually need medical treatment for Graves’ disease and sometimes eyelid surgery.ScienceOpen+1

6. Will radioactive iodine always worsen my eyes?
   Radioactive iodine can increase the risk of eye disease worsening in some patients, especially smokers, but it does not always cause problems. Guidelines suggest using steroid protection in high-risk people or considering surgery instead. The best choice depends on your individual risk factors and should be discussed with your endocrinologist and eye doctor.etj.bioscientifica.com+1

7. How long does biologic therapy like teprotumumab take to work?
   Teprotumumab is usually given as a series of eight infusions over about 24 weeks. Many patients notice improvement in eye bulging and symptoms during the course, but the exact timeline and degree of improvement differ from person to person.FDA Access Data+1

8. Are stem cell treatments available now for Boston’s sign?
   Stem cell approaches for Graves’ orbitopathy are still in the research phase. Studies in animal models and lab settings are promising but not yet ready for routine clinical use. Anyone offering “stem cell cures” outside a proper clinical trial should be viewed with caution.PMC+2SpringerLink+2

9. Can lifestyle changes alone treat Boston’s sign?
   Lifestyle measures like smoking cessation, good sleep, stress control, and eye protection are very important and can make a real difference. However, they usually cannot replace medical treatment of Graves’ disease and thyroid eye disease. Most people need a combination of lifestyle, medicines, and sometimes surgery for best results.Acta Medica Indonesiana+2PMC+2

10. Will eyelid surgery leave big scars?
    Modern eyelid surgery usually uses natural creases or hidden incisions, so scars are often very small and fade over time. The main goal is to improve eye protection and comfort, but many patients are also pleased with the cosmetic results. An experienced oculoplastic surgeon will explain risks and expected appearance.PMC+2EyeWiki+2

11. Can Boston’s sign affect both eyes differently?
    Yes. Thyroid eye disease often behaves differently between the two eyes. One eyelid may be more retracted or move more jerkily than the other. Treatment still aims to calm the overall disease and then fine-tune alignment and lid position for each eye if needed.Wikipedia+1

12. Does Boston’s sign mean I will lose my vision?
    Most people with thyroid eye disease, even with Boston’s sign, do not lose vision if they are monitored and treated correctly. Vision loss usually happens only when optic nerve compression or severe corneal damage is not treated promptly. Regular eye exams and quick action for warning signs greatly lower this risk.PMC+1

13. Is it safe to play sports if I have Boston’s sign?
    Many people can continue sports with protective eyewear and good eye lubrication, but activities with a high risk of eye injury should be discussed with your doctor. Severe proptosis or very exposed eyes may require extra caution. A sports eye shield can reduce injury risk.AestheticEye+1

14. Can makeup or contact lenses worsen Boston’s sign?
    Gentle makeup and properly fitted contact lenses may be safe for some people, but they can irritate dry or exposed eyes. If there is significant eyelid retraction, corneal damage, or active inflammation, doctors often advise avoiding contact lenses and heavy makeup until the surface is healthy again.PMC+1

15. What is the most important first step after noticing Boston’s sign?
    The most important first step is to get a full evaluation from both an endocrinologist and an eye specialist who understands thyroid eye disease. Early diagnosis of Graves’ disease, careful hormone control, eye surface protection, and lifestyle changes like stopping smoking can greatly improve long-term outcomes.etj.bioscientifica.com+2PMC+2
