Diabetic retinopathy screening guidelines for Physicians in India: position statement by the Research Society for the Study of Diabetes in India (RSSDI) and the Vitreoretinal Society of India (VRSI)-2023

Abstract

Diabetic retinopathy (DR) is a leading cause of blindness among working-age adults worldwide. India is the diabetes capital of the world and one in five adults is said to have diabetes in India. With the increase in diabetes, there is an increasing burden of diabetic retinopathy (DR). All patients with diabetes have a risk of losing vision due to DR. The prevalence of diabetic retinopathy is 12.5%; out of which, 4% are said to have vision-threatening diabetic retinopathy (VTDR) The early stages of DR are symptomless, necessitating a proactive screening for an early detection of DR in all people with diabetes before they develop VTDR. This is a position statement jointly developed by RSSDI (Research Society for the Study of Diabetes in India) and VRSI (Vitreo Retinal Society of India) to provide guidelines for Physicians on DR screening in India. These guidelines emphasize the need for regular DR screening of all people with diabetes. It is recommended that the Physicians establish an effective DR screening model in their clinics, eg., a non-mydriatic fundus camera utilizing artificial intelligence (AI) algorithms for fundus photography to identify referral or non-referral DR. This will facilitate early detection and timely referral to an ophthalmologist thereby preventing VTDR. The need to create public awareness regarding blindness due to DR and a collaboration between Physicians and ophthalmologists for the management of diabetes, opportunistic screening of DR, and timely management of DR may play a crucial role in decreasing the burden of blindness secondary to diabetes.
