There are many reasons for exophthalmos, including exophthalmos caused by different reasons, treatment methods and prognosis of the disease. There are two common causes of exophthalmos: one is high myopia, which usually refers to myopia above 600 degrees. At present, there is no effective improvement method, because the occurrence and development of myopia is an irreversible process, so once the performance of exophthalmos appears, there is no way to return to normal. Second, it is found in orbital diseases, such as orbital inflammatory pseudotumor, thyroid-related ophthalmopathy and orbital space-occupying diseases. These diseases are treatable. For inflammatory pseudotumor or thyroid-associated ophthalmopathy, glucocorticoid can be used to control local inflammation and improve symptoms. Orbital space-occupying diseases can be treated by surgery to relieve oppression, thus improving the performance of exophthalmos.
