Web. Web. Diabetic retinopathy: Diabetic retinopathy means damage to weak blood vessels in the retina as a result of diabetes. Uncontrolled levels of sugar in your blood can cause this eye condition, increasing your risk for vision loss. Hypertensive retinopathy: With hypertensive retinopathy, high blood pressure causes retinal damage. Pathophysiology Vascular endothelial growth factor (VEGF) is secreted by the ischemic retina. VEGF leads to a) increased vascular permeability resulting in retinal swelling/edema and b) angiogenesis or new blood vessel formation Diabetic retinopathy pathophysiology Primary prevention Control of glucose and blood pressure..

Diabetic retinopathy is a complication of diabetes. Diabetes can cause the tiny blood vessels in the retina to swell and then bleed or leak fluid. This happens in many parts of the body, and can cause problems like kidney disease and poor circulation to the legs. In the eyes, this process can slowly damage the retina.

On the basis of these findings a working hypothesis for the pathogenesis of diabetic retinopathy is presented. MeSH terms. Diabetic retinopathy is the most common cause of visual loss in working-age adults in the developed world. It occurs following hyperglycaemia-mediated damage within the retinal microvasculature. This damage causes basement membrane thickening, increased capillary permeability and the formation of microaneurysms.
