Highly unusual intra-luminal filling defect (arrow) in the central right internal carotid artery distal to a high grade stenosis indicative of clot (it is too well-defined to represent "turbulent flow"). Small pieces are presumably breaking off to cause amaurosis. On the left there is a a large ulcerated plaque (without significant luminal narrowing) (arrow) presumably associated with thrombus in its base intermittently breaking off and reaching the retinal artery
