A Hollenhorst plaque (also known as a retinal cholesterol embolus) is a cholesterol embolus that is seen in a blood vessel of the retina. It is usually found when a physician performs ophthalmoscopy, during which a plaque will appear as a small, bright crystal that is refractile (reflects the light from the ophthalmoscope) and yellow.[1] This is a medical exam finding, and is not a medical condition, though it may be related to cardiovascular conditions such as atherosclerosis of the internal carotid artery.[1] It was first described by American ophthalmologist Robert Hollenhorst in 1961.[2]
