Aravind works with various diabetes care centres to screen diabetic retinopathy cases through teleconsultation with the help of Aravind Diabetic Retinopathy Evaluation Software (ADRES). Fundus image of the patient with diabetes is captured at the diabetes clinic using a fundus camera which is sent immediately to the Aravind Eye Hospital, where a retina specialist or a trained grader reviews the images and sends a report back regarding the presence or absence of DR within an hour.
