Because various causes lead to optic neuropathy, which ultimately manifests as optic atrophy, the treatment of the cause is the most critical. In the early stage when the optic nerve shows inflammation and edema of different degrees, glucocorticoid should be used in time to control inflammation and prevent the further development of the disease. According to different causes, we should actively treat primary diseases such as poisoning, glaucoma, retinal diseases, tuberculous encephalitis, etc. If there is hypertension, kidney disease, diabetes, which causes optic neuropathy, we should control blood pressure, renal function and blood sugar surgery as soon as possible, such as tumor compression and traumatic injury, we should timely carry out surgery, nutritional diseases, can supplement vitamin B, Neurotrophic drugs and vasodilators are used for treatment. Surgical treatment is mainly aimed at the cause of disease, such as pituitary tumor patients. The tumor compresses the optic nerve. After the tumor is removed, the compression can be relieved and the visual function of patients can be improved.
