Atheromatous embolism of the central retinal artery immediately behind the lamina cribrosa and of one main arteriolar branch of the retina was histologically found as the cause of sudden blindness in one eye of a 74-year-old woman. The main embolus was calcified and contained cholesterol crystal spaces as well as foreign body giant cells. Secondary hemorrhagic glaucoma with rubeosis iridis and angle closure developed subsequently.
