An unusual case of cortical blindness associated with aortography - A casereport

Transient cortical blindness is a rare but well-recognized benign complicat ion of angiography that is due to neurotoxicity of the contrast agent. The blindness completely resolves in a few days. This report describes a patien t suffering an unusual course of cortical blindness following aortography r esulting in permanent, partial blindness. It was found that blindness was t he consequence of bilateral occipital embolisms. This case emphasizes that cortical blindness associatted with angiography does not always have a favo rable outcome, since it might be, in rare cases, due to isolated occipital embolisms, which initially produce a clinical picture identical to that of the neurotoxic effect of contrast agents.
