Figure 1. The patient awoke with a sudden loss of vision superiorly OS. He was diagnosed with an inferior branch retinal artery occlusion. Note the small, white plaque in the inferior retinal vasculature at the optic nerve.

Figure 2. This patient with catastrophic antiphospholipid antibody syndrome noted decreased vision in his left eye shortly after suffering a stroke. Note the arteriolar narrowing and sheathing throughout the retina consistent with the multiple occlusions.

Figure 3. The patient was asymptomatic upon presentation. Fundus examination revealed a small branch retinal artery occlusion superior to the macula and multiple Hollenhorst plaques throughout the retinal arcades. A carotid duplex showed 70 percent stenosis of the left internal carotid artery. He underwent a carotid endarterectomy shortly thereafter. (Photo courtesy Review of Optometry; used with permission)
