Diabetic retinopathy is the retinal disease described here. Chronic high blood sugar damages retinal blood vessels, leading to capillary leakage and hemorrhages. When parts of the retina become ischemic, new, fragile vessels grow (neovascularization) in an attempt to supply blood. These vessels are prone to leakage and bleeding, and the accompanying scar tissue from fibrous proliferation can contract and distort the retina, causing vision loss. This combination of leakage, bleeding, and neovascularization with scarring is characteristic of diabetic retinopathy, especially its proliferative form. Other options don’t fit because macular degeneration is not diabetes-specific and involves different processes, retinoblastoma is a pediatric tumor, and optic nerve hypoplasia is a congenital nerve underdevelopment.
