EYE - Vitreo-Retinal
Diabetic retinopathy (DR) is a complication of diabetes, caused by high blood sugar levels damaging the retinal microvasculature. Mechanisms, such as oxidative stress and deposition of advanced glycation end products, leads to glial cell activation and neuronal apoptosis. Pericytes, contractile...
