A. Fundus image of a patient with moderate nonproliferative diabetic retinopathy (NPDR). Microaneurysms can be seen (black arrows) along with an area containing a flame-hemorrhage (yellow arrowhead) and exudates (white arrow) temporal to the fovea. B. Fundus image of a patient with proliferative diabetic retinopathy (PDR). Multiple areas containing microaneurysms can be seen here (black arrows) along with an area of neovascularization of the optic disc (yellow arrowhead) and exudates (white arrow) superotemporal to the fovea. C. Fluorescein angiogram of patient seen in B. Areas of profound retinal nonperfusion are identified by a star. Numerous white dots (white arrows) indicate the presence of microaneurysms, which are more easily visualized on fluorescein angiograms than color photos. D. Isolated retinal microvessels from a diabetic patient demonstrating numerous capillary microaneurysms (thick arrows) and degenerate capillaries (thin arrows).
