Case Report: Transient cortical blindness following coronary angiography

Temporary blindness, also known as transient cortical blindness, is an uncommon impediment of contrast agent usage during angiography procedures. The occurrence of blindness after a cardiac catheterization procedure is rare and its pathophysiology remains largely speculative. The most probable mechanism seems to be contrast agent-related disruption of the blood–brain barrier, possibly initiated by several predisposing factors. This case reports a 52-year-old man with transient vision loss that occurred following coronary angiography. Brain magnetic resonance imaging (MRI) showed no acute pathology and his vision spontaneously returned within approximately 15 hours post-procedure without any requirement of specific therapy. Suggesting that transient cortical blindness may have occurred following coronary angiography which subsequently self-resolved.

Transient cortical blindness during coronary and aortocoronary bypass graft angiography

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.

A Case of Transient Cortical Blindness in Posterior Reversible Encephalopathy Syndrome in the Late Postpartum Period

Posterior reversible encephalopathy syndrome (PRES) is a reversible neurological entity characterized by seizure, headaches, visual symptoms, impaired consciousness and other focal neurological findings.
