Diabetic Retinopathy

Diabetes is becoming increasingly common in industrialized and even developing countries.  A serious and irreversible complication of diabetes--diabetic retinopathy (DR)--could impact as many as 191 million people around the globe by 2030. Despite the fact that DR is a leading cause of vision loss around the world, as many as 50% of people with diabetes are not getting regular eye exams, or are diagnosed too late for treatment to be effective.  The diabetic retinopathy fact sheet was released on May 19th during a webcast.  Click here to read the transcript, see the slides, and listen to the webcast audio.
