Aim: The primary objective of our study is to quantify the relationship between diabetic retinopathy and urine albumin excretion and to correlate the urinary albumin excretion (normoalbuminuria, microalbuminuria, macroalbuminuria) with the severity and grade (mild, moderate, severe non-proliferative diabetic retinopathy [NPDR] or proliferative diabetic retinopathy [PDR]) of diabetic retinopathy. Here, ALB is linked to non-proliferative diabetic retinopathy.
