[Transient blindness after cardiac angiography with modern contrast media].

A 72 year old man with coronary heart disease underwent cardioangiographic examination using monomeric non-ionic contrast medium. During and after the examination he gradually developed nearly total cortical blindness. His vision slowly returned after two days, but was not fully restored. Computer tomography (CT) of the brain five hours after the examination showed bilateral contrast medium retention in the visual cortex area, which became normal the day after. The gradual development of nearly total blindness combined with bilateral transient CT-alterations in the visual cortex area suggest a complication induced by the contrast medium.
