The incidence of cerebrovascular complications in diagnostic cardiac catheterisations and coronary angiography is low. The National Institutes of Health in America reported a rate of 0.03%,6 and the British Cardiac Society report from 34 041 patients gave an incidence of 0.06%.7 This included cerebrovascular accidents, transient ischaemic attacks and amaurosis fugax. Neither study described transient cortical blindness. Usually neuro-ophthalmologic complications of cardiac catheterisation relate to embolic phenomena or migraine. Cortical blindness is better recognised as a complication of cerebral and vertebral angiography, with an incidence of 0.3%– Transient cortical blindness related to coronary angiography and graft study
