Prevalence of diabetic retinopathy in a primary care setting using digital retinal imaging technology

The objective of this study was to determine the prevalence of diabetic retinopathy in a primary care setting using digital retinal imaging technology and to quantify the degree of diabetic retinopathy using internationally accepted severity scales. Two hundred patients with type 2 diabetes were evaluated clinically followed by fundus photography. The prevalence of retinopathy and maculopathy was 47.4% and 59.2% respectively (both retinopathy and maculopathy 34.7%). The high prevalence of retinal abnormality in this study is a cause for concern as most patients had diabetes for only 5 years or less.
