The article discusses the clinical implications of and treatment options for diabetic retinopathy (DR). DR results from elevated blood glucose that in turn, causes abnormal circulation within the retina, with the development of microaneurysms within the retinal tissue due to the improper forming of new vessel walls. Its severity is divided into the early, nonproliferative stage (NPDR), and the progressed, proliferative or neovascular stage (PDR).
