New eye test could spot retinal disease earlier than ever before

This study aims to see if a device called microperimetry can detect early changes in the central retina (macula) of people with dry age-related macular degeneration or diabetic retinopathy. Researchers will measure how sensitive the macula is to light and compare it with standard eye scans. 200 participants will be tested at the start, 6 months, and 12 months. No treatment is given; the goal is to improve future detection and understanding of these eye diseases.
