J Liaquat Uni Med Health Sci Jan ;10(3):143-6.

OBJECTIVES: To determine the frequency and type of diabetic retinopathy in different age groups. STUDY DESIGN: Descriptive Case series study. PLACE AND DURATION OF STUDY: Department of Ophthalmology Liaquat University of Medical and Health Sciences (LUMHS) Hyderabad, from February 2009 to January 2010. METHODS: Two hundred and forty four patients of diabetes mellitus (DM) were randomly selected and grouped out into 30-40 years, 41-50 years, 51-60 years, 61-70 years and more than 70 years of age. Each patient was evaluated for diabetic retinopathy (DR) by fundoscopy and Fundus Fluorescence Angiography (FFA). The retinopathy was graded as 0-3 grade; grade 0= no DR, grade 1= mild DR, grade 2= moderate to severe DR and grade 3= proliferative DR. The different risk factors (age, gender, duration of DM, treatment type and hypertension) were evaluated in relation to diabetic retinopathy. RESULT: Among 244 patients, 149 were males and 95 were females. Diabetic retinopathy was detected in 100 (40.94%) patients. Mean duration of DM was 13 years in patients with DR and 7.5 years in patients without DR. Most of the DR was found in 40-60 years of age. Out of 244 subjects 25% patients were found with grade 1, 6.96% patients with grade 2 and 9.01% patients were found with grade 3 diabetic retinopathy. CONCLUSION: Most of the diabetic retinopathy cases were below the age of 60-years, and majority of DR cases presented with type 1 diabetic retinopathy.
