Abstract
Patients (4) who sustained bilateral occipital and parietal lobe ischemia during cardiac surgery for coronary artery bypass are described. The features include cortical blindness, visual disorientation, disturbances of reading and constructional dyspraxia. The symptoms tended to improve over about 6 wk and good visual acuity was regained in all instances. The likeliest cause is generalized cerebral hypotension. Ischemic injury might be prevented by prior detection of extracranial arterial disease and by monitoring cerebral and cardiac activity during surgery.
