Transient cortical blindness during coronary and aortocoronary bypass graft angiography

Abstract

The prevalence of cerebrovascular complications after cardiac catheterization is low. These include stroke, transient ischemic attack, and amaurosis fugax. Cortical blindness is a rare, bilateral clinical condition of largely ischemic etiology, characterized by damage to the cerebral cortex, which manifests with acute reduction of visual acuity. Usually, neuro-ophthalmic complications of cardiac catheterization are correlated with embolic phenomena or migraine. We report a case of transient cortical blindness during coronary and aortocoronary bypass graft angiography.
