Study on the association between total vitamin D levels and diabetic retinopathy in type 2 diabetic mellitus

This study aims to recognize the interrelation among total vitamin D levels and diabetic retinopathy in diabetic mellitus particular type 2 variant.That was a cross-sectional look on 276 patients with diabetes mellitus. Cases were grouped similarly into with and without DR.Screening tactics like unique records, best-corrected visual acuity, fundoscopic examination, and blood investigations like fasting blood sugar, post prandial blood sugar, HbA1C vitamin-D were carried out. Diabetic retinopathy is graded the use of ETDRS.The relation of the period of diabetes to the severity of retinopathy showed an advantageous correlation, with a p-value <0.001. It has confirmed an inverse relationship among the severity of diabetic retinopathy and Vitamin D values. Sufferers with mild NPDR and moderate NPDR had Vitamin D insufficiency, which decreased to Vitamin D deficiency stages in severe NPDR and PDR.A relation change is observed among diabetic retinopathy and total Vitamin D levels. Henceforth, it is important to examine the affiliation of Vitamin D with the extent of DR, its use to forecast of the severity of DR, and as a device to restrict or prevent the development of retinopathy modifications.
