Abstract :
Introduction: Diabetes has become a global epidemic. Diabetic retinopathy (DR) is a leading cause of
loss of vision in diabetics. Since the global prevalence of diabetes is estimated to rise exponentially, the
prevalence of DR is also bound to rise. Consequently, a large population will be at risk by DR in near
future.
Materials and Methods: A cross sectional observational study was conducted on eligible diabetic patients.
Demographic data and history was noted. A complete ophthalmic examination in which fundus was
examined by 90 D and 20D lenses. Statistical analysis was performed.
Results: Out of 291 eligible patients, 159 (55%)were males. 76 (26.11%) had DR of which 43
(27.04%)were males. For duration of diabetes (years) 10, DR was found in 5 (6.57%),
30 (39.47%) and 41 (53.94%) respectively. DR in age groups (years) of 80,was
1(2%),32(25%), 44(30%) and 9(100%) respectively. Mild, moderate, severe NPDR and PDR were found in
39(51.31%), 17(22.36%), 13 (17.1%) and 7 (9.2%) patients respectively.
Conclusion: The prevalence of DR is very high in Indian population. Diabetic patients are unaware of
development of DR in early stages. The severity of DR rises with increase in duration of diabetes.
