The Challenge
India has one of the world’s largest diabetes burdens, with an estimated 101 million people living with diabetes, representing an overall weighted prevalence of 11.4%1. Diabetic retinopathy (DR), including diabetic macular edema (DME), is an important cause of vision impairment and blindness among people with diabetes. Early detection and timely treatment can help prevent irreversible vision loss2.
Screening for both DR and DME currently relies on retinal imaging and expert review by trained ophthalmologists—resource-intensive and difficult to scale uniformly, especially with a rural ophthalmologist-to-population ratio of 1:219,0003.
Our AI Solution
MadhuNetrAI is an AI-enabled screening solution designed to assist the health workforce- optometrists, Community Health Officers (CHOs) and medical officers- in early identification of DR and DME from fundus images.
How it works
01
Preparatory stage
the patient is informed about the procedure and moved to an environment suitable for fundus imaging.

AI assessment
the model assigns a DR grade based on severity — Grade 0 (No DR), Grade 1 (Mild), Grade 2 (Moderate), Grade 3 (Severe), Grade 4 (Proliferative) and presence or absence of DME.

Impact
MadhuNetrAI expands access to diabetic eye screening by enabling DR and DME assessment through portable retinal imaging and AI, including in settings where specialist availability is limited. By providing standardized, data-driven screening insights, it supports timely referral and helps healthcare providers prioritize patients requiring specialist attention. The solution demonstrates high diagnostic performance, achieving 96.9% sensitivity and 94.7% specificity, with a Cohen’s kappa of 0.91.
