Abstract

Traumatic optic neuropathy (TON) occurs most in young, otherwise healthy patients and may cause severe, irreversible visual loss. The optic nerve may be injured by direct and indirect trauma. Falls and motor vehicle accidents are the primary causes of TON, and prevalence varies throughout the world, in part because of variable standards for motor vehicle and passenger safety. The precise mechanism for TON has not been established but may be a combination of primary and secondary axonal injury and ischemia. A number of medical and surgical treatments for TON have been proposed, but no standard approach exists. Further research is needed to understand the mechanisms of the injury, the types of optic nerve damage that occur, and the optimal treatment strategies.
