Whether the optic nerve damage with light perception can be recovered is related to the severity of the patient’s condition, if the patient is treated in time there is a possibility of improvement, but it is generally more difficult to fully recover. If the optic nerve is damaged due to trauma or other reasons, and the visual acuity is reduced to light perception, the patient can be treated with optic nerve canal decompression and opening surgery and hormone methylprednisolone shock to improve the optic nerve function in time. Generally, the earlier the treatment is done, the better the result will be, and those with mild condition will have better prognosis as the improvement will be obvious, but generally cannot return to normal completely. If the optic nerve is damaged and not treated in time, the optic nerve atrophies, it is generally more difficult to recover and the prognosis is worse. It is recommended that patients with optic nerve damage and light sensation should be treated in hospital in time to assess their condition and under the guidance of professional doctors for reasonable treatment.
