Choroidal perfusion disorders may range from focal infarction of the choriocapillaris to fibrinoid arteriolar necrosis. Vascular occlusion due to microembolism is more common in choroidal than in retinal vasculature. Due to its unique hemodynamic characteristics, which involve one of the highest rates of blood flow in the body and the fact that it is functionally an end artery system, the choroidal circulation is prone to platelet emboli associated with cardiovascular disease and other pathologies with increased risk of microembolismt.展开更多
