Clinical Trials in DR

Diabetic Retinopathy Clinical Studies

Diabetic retinopathy (DR) is a complication of diabetes that causes damage to the blood vessels of the retina; it is the most common cause of irreversible blindness in working-age Americans. [ASRS.2016]. Vascular endothelial growth factor (VEGF) plays a critical role in promoting angiogenesis and vascular leakage, and several different anti-VEGF agents have been studied in the management of DME, PDR and advanced NPDR.
