Thyroid-related ophthalmopathy, also known as endocrine proptosis and Graves’ ophthalmopathy, is a common complication of hyperthyroidism (hyperthyroidism) and can occur after or before hyperthyroidism. The common manifestations of simple proptosis include outward protrusion of the eyeball, reduced transients, upper eyelid contracture, widening of the eyelid fissure, and abnormal gaze in both eyes. In severe cases, the eyeball is fixed, the eyelid is not fully closed, and the cornea is exposed to form ulcers or total uveitis, and even blindness. Hyperthyroidism is an autoimmune disease and the eye is one of its target organs. However, it should be noted that control of hyperthyroidism is the first and foremost condition for the treatment of thyroid eye disease, and controlling thyroid hormone levels within the normal range is the most important. Other treatments such as immunosuppressants have great side effects, and the proptosis may return to its original level after stopping the medication. For severe infiltrative proptosis in order to improve the ocular signs surgical treatment can be used to release the traction, restore eye movement, eliminate diplopia and improve the appearance.
