Eye protrusion caused by hyperthyroidism requires different treatments depending on the severity of the condition, and can be categorized as either simple protrusion or infiltrative protrusion, with the latter being divided into active and inactive. Simple protruding eyes can be cured when thyroid function is well controlled. Infiltrative synostosis needs to be treated with glucocorticoids, immunologic agents, and so on. 1. Simple synophthalmos is related to poorly controlled thyroid function and thyroid hormone-induced sympathetic excitation. Treatment only requires adjustment of antithyroid medication to stabilize thyroid function, and as long as thyroid function is well controlled, synophthalmos will gradually resolve. 2. Infiltrative synophthalmos is related to immune-induced retrobulbar edema, which can lead to blindness in severe cases. On the basis of stabilizing thyroid function, according to the severity of the protruding eyes, oral or intravenous glucocorticoid therapy can be chosen under the guidance of professional physicians, and immunosuppressive drugs can also be combined. When the internal medicine treatment is unsatisfactory, retropubic radiation therapy or decompression surgery can also be used. Hyperthyroidism caused by protruding eyes, you need to go to the hospital as soon as possible, under the guidance of a professional physician treatment.
