Thyroid Eye Disease
Thyroid eye disease — also called Graves’ orbitopathy or thyroid-associated ophthalmopathy — is an autoimmune condition affecting the tissues around the eyes, most often in people with Graves’ disease.
It can occur before, during or after thyroid dysfunction is treated, and sometimes appears without obvious thyroid symptoms.
Last medically reviewed: 1 November 2025
What happens
The same autoimmune process that stimulates the thyroid can inflame the fat and muscles behind the eye. This pushes the eye forward (proptosis/bulging), causes double vision from muscle enlargement, and produces redness, dryness and a staring appearance.
Severity ranges from mild cosmetic changes to sight-threatening compression of the optic nerve.
Risk factors
Smoking is the strongest modifiable risk factor — it worsens severity and reduces treatment response. Other risks include poorly controlled thyroid function, high TRAb levels, radioiodine treatment in active disease, and female sex (though men tend to have worse disease).
Management
Mild disease: lubricating eye drops, selenium supplements (evidence-supported), and addressing thyroid function. Moderate-to-severe active disease may need immunosuppression — intravenous steroids, and in some cases other agents. Stable disease with residual changes may benefit from surgery (orbital decompression, strabismus or eyelid surgery).
Any sudden vision loss, severe pain or rapidly worsening bulging needs urgent ophthalmology review.
Frequently asked questions
Can thyroid eye disease happen without Graves’?
Rarely — most cases are associated with Graves’ disease, but it can occur with other thyroid conditions or in isolation. Thyroid function testing is still important.
Does treating the thyroid fix the eyes?
Treating thyroid dysfunction is necessary but not always sufficient — eye disease has its own course and may need specific treatment. Achieving and maintaining normal thyroid function helps overall management.
Can I prevent it?
The strongest preventive measure is not smoking. There is no proven way to prevent it entirely, but controlling thyroid function and avoiding radioiodine during active eye disease reduces risk.
