Diabetic retinopathy module in rapid assessment of avoidable blindness (RAAB) survey methodology was used to estimate magnitude of diabetes mellitus (DM) and diabetic retinopathy (DR) in a high risk population in Pune, western India. Sample size of 3527 was calculated based on estimates from previous studies in India. Random cluster sampling with probability proportionate to size was used to select 60 clusters consisting of 60 individuals each. All diabetics (known and newly detected) underwent dilated retina evaluation with indirect ophthalmoscopy to determine their DR status. The prevalence of DM in the sample was (706/ 3221) 21.9 %( 95 CI 20.1-23.7). Prevalence of DR was 14.3% (95% CI 11.7- 16.9). Most diabetics (401/579, 69.3%) never had DR screening done in the past. Cataract was the principal cause of blindness (50% cases) among diabetics. Over fifth of persons above 50 years of age in Pune have DM. Nearly seventh of them have DR but coverage of screening is poor in Pune.
