Figure 1. Demonstration of clinical and experimental diabetes-induced degenerate capillaries. Black arrows are diabetes-induced degenerate capillaries and pericyte ghosts are shown in white arrow, and capillary microaneurysm (MA) in isolated retinal vessels. A: A diabetic patient having non proliferavtive diabetic retinopathy (NPDR). B: A C57Bl/6 mouse after nine months of diabetes. Pericyte ghosts are more difficult to detect in mice retinas than in most other species.
