Abstract

Background: To assess prevalence of diabetic retinopathy in non- insulin dependent diabetes mellitus (NIDDM) patients.
Materials and Methods: One hundred thirty non- insulin dependent diabetes mellitus (NIDDM) patients of both genders were enrolled and the prevalence of DR was recorded. Retinopathy was classified as mild non-proliferative retinopathy, moderate non-proliferative retinopathy and severe retinopathy.
Results: Out of 130 patients, males were 70 (53.8%) and females were 60 (46.2%). Out of 70 males, 42 (60%) males and out of 60 females, 28 (46.6%) females had diabetic retinopathy. The difference was significant (P< 0.05). Out of 70 diabetic retinopathy patients, mild non-proliferative retinopathy was seen in 14 males and 8 females, moderate non-proliferative retinopathy was seen in 18 males and 12 females, severe non-proliferative retinopathy was seen in 10 males and 8 females. The difference was significant (P< 0.05). Duration of diabetes was <5 years was seen in 14, 5-10 years in 26 and >10 years in 30. In 45 patients with DR, family history was positive. DR was present in patients with BMI <24.9 in 13, 25-29.9 in 15 and >30 in 42. Hypertension was seen in 48. The difference was significant (P< 0.05).
Conclusion: Results showed that maximum cases of diabetic retinopathy were seen in patients with BMI >30, hypertension and with 5-10 years of diabetes and with positive family history of diabetes.
