Thyroid Eye disease [Gravesâ disease] is an auto-immune disease that causes inflammation of the Thyroid gland. It is frequently associated with inflammation of the extraocular muscles and orbital fat. The effects on the eye may be temporary and reversible.
Although Gravesâ Ophthalmopathy is caused by a hyperactive thyroid, the hormones that affect the eyes are not the same ones that cause reactions in other parts of the body. In roughly 10% of cases, people with Gravesâ Ophthalmopathy do not actually have Gravesâ disease. In extreme cases of Gravesâ Ophthalmopathy, swollen eye muscles may put extreme pressure on the optic nerve, leading to double vision, or vision loss.
