The solution will help prevent and cure diabetic retinopathy which has been increasingly spreading across the country

Kolkata: IIT, Kharagpur has developed a software for early-detection of diabetic retinopathy. This is a diabetes-related problem that could lead to blindness. Patients suffering from diabetes for more than 10 years are susceptible to this disease.

Funded by IBM India, the software would also help in risk categorisation of the disease. Titled Computer Vision Approach to Diabetic Retinopathy Screening, the project is now being used on a pilot basis at a hospital in the city with encouraging results, Chandan Chakrabarty of IIT Kharagpur, who is principal coordinator of the project, said.

The software uses data analytics capabilities to automatically compare and analyse retina images of the patient. It not only detects whether the patient has diabetic retinopathy, but also provides risk categorisation ranging from low to medium and high, Chakrabarty said.

DR is an ocular manifestation of systemic disease, which affects up to 80 percent of all patients who have had diabetes for 10 years or more.

The project was initiated March 2011 by the IIT Kharagpur, in association with IBM India and Susrut Eye Foundation and Research Centre (SEFRC), Kolkata.

“The solution is being used in our clinic and the results are very encouraging, in fact, the accuracy level is as high as 92 percent,” said Anirudh Maity of SEFRC, where the project is being used on a pilot basis.
