A Case of Transient Cortical Blindness after Cardiopulmonary Resuscitation

ABSTRACT

Cortical Blindness is loss of vision due to injury of geniculocalcarine visual tract, usually caused by cerebrovascular disease. Cardiac arrest leads to global brain hypoxia or to more focal neurologic deficits. Cortical blindness is one form of these focal neurologic deficits. The severity of visual disturbance in cortical blindness is variable, so the diagnosis can be made later unless emergency physicians are familiar with it. We report a case of transient cortical blindness following hypoxic episode caused by coronary vasospasm.
