Abstract

Aim:The study compares grade of diabetic retinopathy(DR) determined by fundus photo(FP) taken by a portable fundus camera and indirect ophthalmoscopy(IO). Method:Diabetic patients were screened in the physician’s clinic. After dilatation, FP was taken by a trained optometrist using fundus camera and an ophthalmologist recorded DR grading using IO. FP were later graded by second ophthalmologist blinded to IO grading. Result:3110 eyes of 1553 subjects were screened across 13 districts of West Bengal over 12 months. Prevalence of DR by FP and IO was 18.35% and 21.51% respectively. Sensitivity and specificity of the camera was 76.37% and 98.40% respectively. Positive and negative predictive values were 91.45% and 94.88% respectively. The accuracy in determining grade of DR was 89.19%. Its accuracy was better in predicting absence of DR (95.3%). Conclusion:The portable fundus camera operated by an optometrist can be a valuable tool for screening diabetic retinopathy in outreach areas.
