title: Cortical blindness after motorcycle accident: a case report.
abstract: A 47 year-old Thai man presented with acute bilateral blindness after suffering head trauma in a motorcycle accident. No neurological deficit was found. The visual acuity was light perception with poor light projection on both eyes. Other ocular examinations were normal except ecchymosis on both lower eyelids and mild subconjunctival hemorrhage on the left eye. Emergency computerized tomography showed normal appearance of optic nerves, optic canals and multiple contusional intracerebral hemorrhages at both occipital lobes. This case demonstrated a rare condition of permanent cortical blindness without other neurological deficits resulting from a head trauma.
