The occurrence rate of transient cortical blindness after contrast media exposure has been reported to be as high as 1% to 4% after cerebral or vertebral angiography, but such blindness has been described in only a few cases of coronary angiography with modern, non-ionic, low-osmolality radio-contrast agents. In this study, we present a case of abrupt cortical blindness after exposure to contrast media during diagnostic coronary angiography; to our knowledge, this is the 1st report in the medical literature that describes transient cortical blindness after iobitridol use.
