• A man complaining of blurred vision had diffuse retinal capillary telangiectasia as a primary retinal finding. Evaluation of the carotid arteries by a noninvasive angiographic method revealed bilateral, silent occlusions of both common carotid arteries. Thus, some cases of "idiopathic retinal capillary telangiectasia" may in fact be harbingers of underlying carotid artery disease.
