title: Cortical blindness after cerebral angiography. Case report.
abstract: A case of cortical blindness after cerebral angiography is presented. Serial computerized tomography scans of the brain revealed persistence of contrast medium in occipital visual areas as well as areas that may have been associated with "focal seizures" that occurred after angiography. This case supports the concept that cortical blindness may be secondary to the direct effect of contrast medium on the brain. The persistence of contrast material was in part due to decreased renal function.
