The Wisconsin Epidemiological Study (25)has proved that microvascular complications such as diabetic retinopathy (DR) in the diabetic population are linked to the duration of the disease. Diabetic retinopathy occurs both in type 1 and type 2 diabetes mellitus. Nearly all type 1 and 75% of type 2 DM will develop DR after 15 year duration of diabetes.(25) During the first two decades of disease, nearly all patients with type 1 diabetes and >60% of patients with type 2 diabetes have retinopathy.(26)
It is estimated that 15 to 25% of the diabetic population have diabetic retinopathy, and everyone has the potential to develop it over a period of time. (15)
More than 75% of patients who have diabetes mellitus for more than 20 years will have some …show more content…

The CURES Eye study is the first population-based study, which used four-field stereo retinal photographs and Early Treatment Diabetic Retinopathy Study (ETDRS) grading to document DR in the Indian population (27)
The prevalence of DR in different socio-economic groups was studied in the Chennai Urban Population Study (CUPS), a population based study conducted in Chennai, involving two residential areas representing the lower and middle income group. The prevalence of DR in the middle income group was 21.1 per cent compared to 14.3 per cent in the low income group …show more content…
Individuals with more than of 20 years of age were screened for diabetes and all the subjects underwent four –field colour fundus photography. The results showed that the overall prevalence of Diabetic Retinopathy was significantly higher in men than women. Logical regression analysis showed that for every five years increase in the duration of Diabetes, the risk increased 1.89 fold. The study concluded that Diabetic Retinopathy is likely to pose a public health burden in India; hence routine retinal examination is mandatory to detect this case in the early
