On World Diabetes Day, India unveiled updated national guidelines for the prevention and management of diabetic retinopathy (DR), a leading cause of vision impairment among adults with diabetes. The guidelines, released at a National Summit in New Delhi, are designed to strengthen early detection, standardize diagnosis and treatment, and integrate DR care into the broader health system. With over 101 million people living with diabetes in India and numbers projected to rise, the new recommendations mark a critical step in addressing the growing threat of diabetes-related blindness.

The Scope of Diabetic Retinopathy in India

Diabetic retinopathy is a complication of diabetes that damages the blood vessels in the retina, potentially leading to vision loss or blindness if left untreated. Recent studies estimate that about 12.5% of people with diabetes in India have some form of DR, with approximately 4% experiencing vision-threatening diabetic retinopathy (VTDR). The prevalence is similar across urban and rural areas, though it increases with age and duration of diabetes. With India’s diabetes population expected to reach 109 million by 2035, the burden of DR is set to grow, making early intervention essential.

Key Features of the New Guidelines

The updated guidelines emphasize several critical actions:

Annual retina screening for all individuals with diabetes, regardless of symptoms, to detect DR at its earliest stages.
Standardized protocols for diagnosis and treatment, ensuring consistent care across different regions and healthcare settings.
Integration of DR screening into primary healthcare, making it easier for patients to access timely eye exams.
Use of digital technologies such as teleophthalmology and AI-based screening tools to improve access, especially in underserved areas.

Dr. Rajesh Saini, President of VISION 2020 India, highlighted the importance of these guidelines: “Diabetic retinopathy is silently threatening the vision of millions. These new guidelines—rooted in expert consensus and aligned with current best practices—will enable earlier detection and intervention, particularly in underserved communities”.

Expert Perspectives and Global Context

Experts agree that early detection and timely treatment can prevent most cases of diabetes-related vision loss. Dr. Praveen Vashist, Secretary of VISION 2020 India, noted that “these guidelines are catalysts for systemic change. Our aim is to ensure that every individual at risk receives timely screening, diagnosis and care, regardless of geography or socioeconomic status”.

Globally, the World Health Organization (WHO) recommends regular DR screening for all people with diabetes, alongside prompt treatment for those who need it, as an effective intervention to prevent vision impairment and blindness. The new Indian guidelines align with these international standards, emphasizing the importance of multidisciplinary care and patient education.

Practical Implications for Patients

For individuals living with diabetes, the most important takeaway is the need for regular eye check-ups. Annual retina screenings can detect DR before symptoms appear, allowing for timely intervention and reducing the risk of vision loss. In addition to screening, maintaining good control of blood sugar, blood pressure, and cholesterol levels is crucial for preventing the progression of DR.

Limitations and Challenges

Despite the promise of these guidelines, challenges remain. Awareness about DR and the importance of screening is still low among both patients and some healthcare providers. Access to specialized eye care is limited in rural and underserved areas, and integrating DR screening into primary care will require sustained investment and training. Furthermore, while the guidelines provide a strong framework, their effectiveness will depend on implementation and ongoing monitoring.

Conclusion

The release of new national guidelines for diabetic retinopathy represents a significant advancement in India’s efforts to combat diabetes-related vision loss. By promoting early detection, standardized care, and greater access to screening, these guidelines have the potential to protect the vision of millions of people with diabetes. However, continued efforts are needed to raise awareness, improve access, and ensure that all individuals at risk receive the care they need.
