This project aims to implement smartphone-based screening for early detection of diabetic retinopathy (DR) in India, Bangladesh, Nigeria, and Ghana, targeting regions served by partner organizations. By increasing detection rates of this common yet often undiagnosed diabetes complication, the project seeks to prevent avoidable blindness. A total of 572 mobile screening camps will be conducted by trained healthcare personnel using cost-effective smartphone retinal imaging. The approach is enhanced with telemedicine, AI-assisted image analysis, and scientific evaluation to assess scalability, efficiency, and sustainability. The project builds on extensive prior work and clinical partnerships, focusing on the third phase for expansion and evaluation.
