Cortical blindness, a rare complication of pre-eclampsia.

This is a case report of a previously undiagnosed pregnant teenager who presented to the emergency department with cortical blindness. She was found to be pre-eclamptic with the HELLP syndrome. She underwent immediate cesarean section, with delivery of a viable 32-week-old infant. Computed tomography and magnetic resonance imaging studies revealed abnormalities in the occipital lobes and a possible subarachnoid hemorrhage. Her vision improved immediately after the cesarean section, and returned to normal in a few days.
