Transient Cortical Blindness Following Coronary Angiography

Coronary angiography (CA) became the golden tool for coronary artery disease (CAD) management. Transient
cortical blindness following coronary angiography (TCBCA) is a rare complication of CA, in comparison with the
other common complications. The neurotoxic effect of contrast medium is the possible cause of this clinical
phenomenon, by disrupting blood brain barriers (BBB). TCBCA usually occurs during or immediately after CA. The
clinical picture includes loss of vision that progressively resolves within hours or days. Ophthalmologic examination
reveals normal findings, while computed tomography scan (CT scan) may show contrast accumulation in the
occipital area. No current clinical protocols to manage this condition, except of excluding other possible causes of
blindness after CA. Further well-organized studies are recommended to understand this clinical phenomenon, and
more effort is needed to set a variety of interventional strategies regarding TCBCA management.
