    Hollenhorst's plaques are glistening yellow cholesterol emboli within the retinal arterial system.
    Hollenhorst plaques occur in about 20% of eyes that have central retinal artery occlusions. They most likely originate from atherosclerotic deposits within the carotid arteries. Interestingly, the central retinal artery itself may have atherosclerotic plaque that may produce emboli.
