Hyperthyroidism (hyperthyroidism) refers to a group of diseases caused by excessive secretion of thyroid hormone (TH) in the body due to various etiologies, resulting in increased excitability and hyper-metabolism of the nervous, circulatory and digestive systems. The etiology of hyperthyroidism is complex, with Graves’ disease being the most common, accounting for about 85% of cases. Therefore, the eye disease associated with it should be accurately called thyroid-associated ophthalmopathy (TAO). In addition to hyperthyroidism, hypothyroidism (hypothyroidism) and partially normal thyroid function can also occur in thyroid-related ophthalmopathy. In addition to Graves’ disease, about 15% of other diseases can also cause thyroid-related ophthalmopathy.
