Diagram demonstrating choroidal arteriovenous vasculature. Healthy (bottom) and diseased (top) choroidal arteriovenous vasculature. In the abnormal choroidal arteriovenous vasculature, pathological anastomoses that bypass the capillary bed may form to cause an increased arterial filling in the vortex veins, leading to vortex vein congestion. This engorgement can lead to choriocapillaris congestion, leading to the release of angiogenic factors and the breakdown of the RPE as seen in CSCR. Reprinted with permission from Brinks et al.
