Bilateral optic nerve injury is a rare condition and is reported in 5-6 percent of all optic nerve injuries. However, there is no published series on bilateral optic nerve injury. Analysis of 31 cases of bilateral optic nerve involvement seen amongst 275 patients with optic nerve injury (11.5 percent) is discussed. Road traffic accident which is the most common cause of optic nerve injury, was recorded in 61 percent. Shotgun injury and blast in jury was the cause in 22.5 percent of cases. All the patients except 4 received steroids. Anterior cranial fossa fracture and opacity of paranasal sinuses were recorded in a third of the patients. Visual evoked potentials were recorded in 27 patients. Improvement in vision was noticed in 23 patients (74 percent). However, among the 62 eyes, 39 eyes showed improvement (62.8 percent). Possible reasons for better outcome in bilateral optic nerve injury are discussed.
