A significant association (P<0.001) was observed between the duration of diabetes and the presence and severity of diabetic retinopathy. The overall prevalence of nephropathy, neuropathy, diabetic foot, CVS, CAD was 52.6%and they were significantly (p<0.05) more common in patients with DR (64.8%) as compared to those with no DR (43.5%) and complications increased with severity of retinopathy.
