Angiopathy is the generic term for a disease of the blood vessels (arteries, veins, and capillaries). The best known and most prevalent angiopathy is diabetic angiopathy, a common complication of chronic diabetes. While not exclusive, the two most common forms are Diabetic retinopathy and Diabetic nephropathy, whose pathophysiologies are largely identical. In diabetes, chronic dysregulated blood glucose is toxic to cells of the vascular endothelium which passively assimilate glucose. In diabetic retinopathy the end-result is often blindness due to irreversible retinal damage.
