Hollenhorst Plaque
The trapped at the bifurcation of retinal arterioles is probably a platelet-fibrin-cholesterol embolus. Called a Hollenhorst plaque, it originated in an atheroma of the cervical carotid bifurcation.
Most retinal emboli arrive at their stopping points without infarcting the retina, as shown here. But if they plug an important proximal feeder vessel, they may cause a and a disturbing visual field defect.
