Renal cortex echogenicity increases degree of retinopathy in diabetes mellitus

Abstract

BACKGROUNDThe number of people with diabetes mellitus (DM) is increasing due to population growth, aging, and increasing prevalence of obesity. Diabetic retinopathy and diabetic nephropathy are two main complications of DM. Some studies suggest a correlation between diabetic nephropathy and diabetic retinopathy. However, other studies found that renal cortex echogenicity is associated with chronicity of kidney disease and renal histopathology. The aim of this study was to determine whether there is a correlation between renal cortex echogenicity as determined by renal ultrasonography and degree of retinopathy as determined by funduscopy in subjects with DM.
