Traumatic Optic Neuropathy: The Forgotten Concussion

Cerebral concussions are a well-recognized issue in military and civilian practice. Although most physicians are well versed in recognizing concussion symptoms, many are not as adept at diagnosing and managing comorbid traumatic optic neuropathy (TON). Traumatic optic neuropathy typically follows cerebral concussions but is often not diagnosed as its symptoms are attributed to brain injury or the presence of altered consciousness impedes its recognition. We hereby describe a soldier who sustained a cerebral concussion with an associated unrecognized TON. We review the epidemiology, pathophysiology, diagnosis, and management of TON.
