Patients with optic nerve damage who can only see in the upper half of their vision can usually regain some function with aggressive intervention, but if the condition is severe, recovery is usually difficult. Patients with optic nerve damage may have visual field defects, and recovery depends on the severity of the disease. Patients with optic nerve damage can use medication as prescribed by the doctor to promote vasodilatation and improve blood circulation to achieve recovery from optic nerve damage, such as methylcobalamin, vitamin B12 and so on. If the condition is mild and treated in time, the patient’s prognosis is good and partial function can be restored. In addition, hyperbaric oxygen chamber can improve tissue hypoxia, reduce intraocular pressure to promote optic nerve repair, optic nerve injury patients can also take this way of treatment to improve the discomfort symptoms. If the patient’s condition is serious and the optic nerve damage is obvious, the prognosis is usually worse and the symptoms of visual field defect cannot be improved. It is recommended that patients with optic nerve damage seek medical attention to evaluate their condition and follow the doctor’s instructions for treatment.
