Prevalence of and factors associated with diabetic retinopathy among diabetics in Nepal: a hospital based study.
Diabetic retinopathy is the one of the leading cause of visual impairment in world including Nepal. The objective of the study is to estimate the prevalence of and factors associated with Diabetic Retinopathy among diabetics in a Tertiary Eye Care Centre, Nepal. A hospital-based, cross sectional study, was conducted at Tilganga Eye Centre, Nepal. 371 consecutive subjects were recruited during a period of study. Ophthalmologist performed comprehensive eye examinations, which were reconfirmed by senior ophthalmologist. Diabetic Retinopathy was graded using the Early Treatment Diabetic Retinopathy Study. Total 371 consecutive diabetics were examined, mean of 57.4 years (SD 12.0) having the sex ratio of 0.72 male per female. The prevalence of Diabetic Retinopathy was 44.7% (166) with non-proliferative Diabetic Retinopathy presented 85.5% (142) and 14.5% (24) were proliferative Diabetic Retinopathy. Clinically significant macular edema was found in 19.2% (32). The age at onset of diabetes, duration of diabetes and hypertension were significantly associated with Diabetic Retinopathy (p = < 0.05) whereas ethnicity, sex and cataract surgery were not associated with it (p = > 0.05). The prevalence of Diabetic Retinopathy was within the range of previous studies with a high rate of proliferative diabetic retinopathy. Factors associated with diabetic retinopathy were similar to other developed countries. To prevent this condition of Diabetic Retinopathy, the coordination between physician and ophthalmologist needs to be strengthened.
