Fig. 11. A–C. Proliferative diabetic vitreoretinopathy. Neovascularization from the disc and retina involves vascular endothelial cell migration and proliferation onto and into the posterior vitreous cortex. These photomicrographs demonstrate the growth of neovascular complexes into the posterior vitreous cortex of a human eye (bar = 10 μm).
