Trauma-induced altitudinal hemianopsia.

A 55-year-old Caucasian female presented with bilateral inferior altitudinal visual field defects which resulted from trauma suffered in an automobile accident. In addition, there was a bilateral reduction in visual acuities and bilateral optic disc pallor. Diagnostic and historical data suggested that the primary site of damage was at the occipital cortex. A subsequent bilateral anterior ischemic optic neuropathy process was also thought to have occurred.
