India, often referred to as the “diabetes capital of the world,” is facing a pressing health crisis, with over 101 million people diagnosed with diabetes. The surge in diabetes cases has led to a corresponding increase in diabetes-related complications, particularly preventable vision loss. This alarming trend highlights the urgent need for comprehensive screening and management strategies to address diabetic retinopathy, a leading cause of blindness among working-age adults in the country.
Diabetic retinopathy (DR) is a complication of diabetes that affects the eyes and can lead to severe vision impairment or even blindness. The condition results from damage to the blood vessels in the retina due to prolonged high blood sugar levels. Unfortunately, diabetic retinopathy often goes unnoticed in its early stages, earning it the moniker “silent thief of sight.” By the time symptoms appear, significant damage may have already occurred, underscoring the importance of regular eye examinations.
Currently, India has a national prevalence rate of approximately 12.5% for diabetic retinopathy, with around 4% of individuals at risk of vision-threatening forms of the disease. This translates to nearly 3 million people who are at risk of vision loss due to this preventable condition. The implications of undiagnosed diabetic retinopathy extend beyond health; they pose a considerable economic burden as well, affecting individuals’ productivity and overall quality of life.
Early detection through regular screening is crucial for preventing irreversible vision loss. Timely intervention can significantly reduce the risk of complications and improve health outcomes. To this end, the Vitreo Retinal Society of India (VRSI) and the Research Society for the Study of Diabetes in India (RSSDI) have launched a groundbreaking initiative aimed at enhancing screening practices for diabetic retinopathy across the country.
The newly introduced Diabetic Retinopathy Screening Guidelines serve as a vital resource for healthcare professionals, particularly physicians and diabetologists, who are often the first point of contact for individuals living with diabetes. Here’s a closer look at the key recommendations outlined in the guidelines:
Initial Eye Examination: Individuals diagnosed with type 1 diabetes are recommended to undergo their first eye examination five years after their diagnosis. Early detection is critical, and a five-year wait is a precautionary measure to monitor potential developments.
Initial Eye Examination: For those diagnosed with type 2 diabetes, an eye examination is advised at the time of diagnosis. This early screening is essential, as many individuals may already have some degree of diabetic retinopathy at the time they are diagnosed with diabetes.
1. Eye Examination Prior to Conception: Women with diabetes should have their eyes examined before conception to establish a baseline for their eye health.
2. Early First Trimester Examination: A follow-up eye examination is recommended early in the first trimester of pregnancy.
3. Individualized Follow-Up: The need for additional follow-up examinations should be based on the severity of retinopathy and any recent changes detected.
No Apparent Diabetic Retinopathy (DR): Patients showing no signs of diabetic retinopathy should undergo annual fundus photo screening at their physician’s clinic. This preventive measure aids in early detection of any changes.
Evidence of DR or Diabetic Macular Edema (DME): If there is any evidence of diabetic retinopathy or diabetic macular edema, an immediate referral to an ophthalmologist is necessary for further assessment and management.
These guidelines emphasize the role of healthcare professionals in educating patients about the risks associated with diabetic retinopathy and the importance of regular screenings.
Dr. Sudha Chandrashekar, former Executive Director of the National Health Authority, highlighted that to protect the vision of millions of Indians living with diabetes, diabetic retinopathy screening has been integrated into the government’s Ayushman Bharat scheme. This national program aims to ensure that every individual, particularly those from economically disadvantaged backgrounds, has access to essential healthcare services.
By prioritizing early detection through national initiatives, the government seeks to preserve eyesight and improve overall health outcomes. The screening initiative is especially beneficial for beneficiaries of the Ayushman Bharat – Pradhan Mantri Jan Arogya Yojana (AB-PMJAY) scheme. By focusing on early detection, the program aims to reduce the financial burden associated with managing advanced stages of diabetic retinopathy, which often require costly interventions.
Dr. R. Kim, President of VRSI, emphasized the importance of collaboration between physicians, diabetologists, and ophthalmologists. The newly unveiled guidelines serve as a standard for diabetic retinopathy screening in India, encouraging a team-based approach to diabetes management. This collaboration is crucial for promoting better management of diabetes and reducing the incidence of preventable vision loss across the nation.
Dr. Manisha Agarwal, General Secretary of VRSI, pointed out that despite the increasing prevalence of diabetic retinopathy, there remains limited awareness among patients. Many individuals with diabetes are unaware of the importance of regular eye screenings, largely due to the often asymptomatic nature of the condition. Therefore, raising awareness about the risks of vision loss due to diabetic retinopathy and the necessity of timely screening is imperative.
Dr. Sanjay Agarwal, Secretary General of RSSDI, further highlighted that the growing number of diabetes patients in India necessitates not only monitoring glucose levels but also undergoing regular screenings for complications like diabetic retinopathy. Left untreated, this condition can lead to severe and often irreversible vision loss. The guidelines will play a pivotal role in increasing awareness among general physicians and diabetologists about the critical need for timely screening.
The launch of the Diabetic Retinopathy Screening Guidelines marks a significant milestone in India’s approach to diabetes management. By providing healthcare professionals with the necessary tools and knowledge to promote early detection and intervention, this initiative aims to reduce the risk of severe vision impairment and blindness caused by diabetic retinopathy.
As India grapples with a growing diabetes epidemic, awareness, education, and timely screening are vital in preventing vision loss and improving health outcomes for millions of individuals living with diabetes. By prioritizing eye health, the country can take significant strides toward safeguarding the vision of its population and alleviating the burden of diabetes-related complications.
