title: Foreign body embolism of retinal arteries as a complication of carotid angiography.
abstract: Two cases of foreign body embolism of the retinal arteries after percutaneous carotid angiography were encountered within a period of 7 months. Both patients were non-arteriosclerotic. Loss of visual function in direct relation to carotid angiography and the observation of a dark foreign body in a retinal arteriole indicated exogenous embolism. No or only slight remission occurred. Careful ophthalmoscopy in cases of visual complaints after carotid angiography is advised, and if foreign body embolism is suspected, treatment with vasodilators (e. g. amyl nitrite) should be given a trial.
