The double vision caused by traumatic brain injury may be caused by the damage of ophthalmic nerve and peripheral nerves after traumatic brain injury, resulting in imbalance of eye movement, and the recovery period is usually around three to six months, and the specific time is related to the degree of injury and physical condition. If the patient’s condition is mild, without other uncomfortable symptoms and in good physical condition, under the guidance of the doctor, you can take methylcobalamin and other nutritive nerve medication, and if the effect of medication is unsatisfactory, surgical treatment is also feasible, and the symptoms can be gradually recovered in three to six months or so. If the symptoms are serious and the body is relatively weak, the recovery time will be relatively longer, the specific recovery time is related to the severity of the patient’s condition and physical state, with individual differences. It is recommended that patients with double vision after traumatic brain injury should consult a doctor promptly to assess their condition and follow the doctor’s instructions.
