Prospective Cohort Study on Predicting the Progression of Diabetic Microangiopathy Using Multimodal Eye Imaging
China250 participantsStarted 2025-01-01
Plain-language summary
To develop an artificial intelligence (AI) model to predict DR progression based on a prospective cohort database.With use of an innovative AI model and a validated machine learning algorithm, based on multimodal vascular and neuro imaging of the eye, the progression of diabetic microangiopathy especially the DR could successfully be predictse and fundamentally facilitate diabetes management.
