Neuro-ophthalmological findings in closed head trauma.

Abstract

Visual abnormalities following closed head trauma are common and can affect any part of the visual pathway. We reviewed 181 consecutive patients referred with visual complaints following closed head trauma. A motor vehicle accident was the most common etiology of trauma in 57% of cases, direct trauma to the head in 15%, and injuries sustained from a fall in 13%. Sixty-three percent of patients lost consciousness and 26% suffered a skull fracture. Thirty-five percent of all patients had visual field defects with functional (tunnel) fields the most common. Over 88% of eyes had 20/20 or better visual acuity. Thirty-three percent of patients suffered a cranial nerve palsy, with 75% resolving without intervention. The severity of head injury was directly related to the lack of proper seat belt and helmet use. Most visual complaints were improved with a simple refraction. Most binocular diplopia cleared with time, with only 15 cases requiring surgical correction.
