Objective: To determine frequency of diabetic retinopathy associated with high level of glycosylated hemoglobin HbA1c in blood. Design & duration: This is a cross sectional study of observational type completed in eight months duration. Setting: Study was conducted at ophthalmology department of Bahawal Victoria Hospital Bahawalpur. Patients & methods: Diabetic patients presenting to out-patient door of ophthalmology department of study hospital were selected via non probability consecutive sampling technique. Sample size was calculated using WHO sample size calculator. Retinal examination was done in all patients. Those having retinopathy in study group were put into separate group. Blood level of HbA1c was tested in all cases of study group. Frequency of proliferative and non-proliferative diabetic retinopathy was determined. Consent was taken from all cases in study group and from ethical committee of the study institution as well. Chi square test was applied. P-value less than 0.05 was taken significant. Results: Total 180 diabetic patients were studied out of them 58.3% were male and 41.7% were female. Mean age of patients was 51±11.3 years. Mean HbA1c level was 8.3±1.6. Proliferative retinopathy was observed in 36.2% and non-proliferative retinopathy was seen in 63.8% out of total 47 cases with retinopathy. Conclusion: Diabetic retinopathy is associated with high blood level of glycosylated hemoglobin and nonproliferative retinopathy is more common than proliferative retinopathy.
