Abstract

Cortical blindness has been occasionally reported as a complication after cerebral angiography, but is rare after coronary angiography. The contrast agent is believed to be responsible for the sudden development of blindness. Although the exact mechanism is unknown, it appears that the contrast agent disrupts the blood brain barrier, mostly in the occipital areas. We report a 77-year-old man who suddenly developed transient, bilateral cortical blindness 4 hours after coronary angiography. Using contrast enhancement, the CT scan showed typical, symmetrical involvement of both occipital lobes. There were no other neurological deficits. Vision and CT findings returned to normal within 48 hours.
