Abstract

Background: Diabetic retinopathy is a common microvascular complication of diabetes mellitus and one of the leading causes of acquired blindness. Microalbuminuria reflects a pathophysiological state of vascular dysfunction and organ damage. It is noticed that a rise in urinary albumin excretion is seen in the early phase of diabetic retinopathy. The concordance of microalbuminuria and diabetic retinopathy has been well reported in type 1 diabetes; however, for type 2 diabetes, there is a paucity of data.
Objective: To estimate the prevalence of microalbuminuria in diabetic retinopathy patients with type 2 diabetes attending the out-patient department (OPD) in a tertiary care center in eastern India and also to find out any association between microalbuminuria and severity of diabetic retinopathy.
Material and Methods : The study included 200 patients with type 2 diabetic patients having diabetic retinopathy. The study populations were selected by thorough clinical examination and as per inclusion–exclusion criteria. Estimation of urinary albumin and albumin creatinine ratio was done by using Konelab 20 Autoanalyzer machine by the immunoturbidimetry method. Diabetic retinopathy was classified as per the International Clinical Diabetic Retinopathy Severity Scales into mild, moderate, severe, very severe non-proliferative as well as proliferative diabetic retinopathy. Data were analyzed with ratio, rate, percentage, and statistical significance was considered if p<0> Results: The prevalence of microalbuminuria was found in 36% (72 patients). The highest number of patients (88.24%) with microalbuminuria was found in severe NPDR. 93.06% of patients with microalbuminuria had clinically significant macular edema. A statistically significant correlation (p<0> Conclusion: A significant correlation was found between urinary microalbumin and the severity of diabetic retinopathy.
