Thyroid eye disease, commonly referred to as TED, is an autoimmune, inflammatory condition in which the body’s immune system attacks the tissues around and behind the eyes.

Most often, TED occurs when the thyroid gland is overactive. In rare cases, TED can occur in people who have normal or underactive thyroids. An estimated 85% of people with TED will also have Graves’ disease, a different autoimmune condition also caused by an overactive thyroid. Given the close association between these two autoimmune conditions, TED is sometimes referred to as Graves’ eye disease, Graves’ ophthalmopathy, and Graves’ orbitopathy.
