A Japanese university developed an image-diagnosis support system using artificial intelligence by giving it 500,000 eye images. The system reduced the time needed for diagnoses to a third and helped with early detection of glaucoma and other diseases that can cause blindness if left untreated. Separately, a hospital that does about 8,000 eye surgeries annually has developed an AI system to prevent errors. We report on how AI is helping amid an increase in eye diseases as the population ages.
