AI-driven eye screening aims to close the diabetic vision gap in community clinics

A new trial will evaluate whether integrating autonomous AI screening for diabetic retinopathy into U.S. federally qualified health centers can boost screening completion and accelerate early detection. The DRES-POCAI protocol tests a real-world, point-of-care model that links FDA-cleared AI with electronic health records to close gaps in diabetes eye care.

AI algorithm proves more accurate than experts in glaucoma detection

While artificial intelligence (AI)-powered screening has been validated for diabetic retinopathy, applying the technology to glaucoma has proved more challenging because glaucoma is not one disease. A glaucoma diagnosis is based on a constellation of symptoms, diagnostic tests, and longitudinal data.
