Retinal cholesterol embolus

In this photo of a retinal cholesterol embolus ("Hollenhorst plaque"), note the bright, refractile nature of the lesion, as well as the typical location at a bifurcation of vessels. Note also the lack of distal retinal ischemia, not uncommon with these plaques. (Contributed by Dr. Gregory van Stavern.)
