Diabetic retinopathy screening using tele-ophthalmology in a primary care setting.

We evaluated tele-ophthalmology for diabetic retinopathy screening in a primary care setting. Four general practitioners (GPs) were taught to assess non-mydriatic retinography images of patients with diabetes. After training, a total of 1223 patients were screened using this method: 926 (76%) did not have diabetic retinopathy and 297 (24%) were referred for an ophthalmologic assessment.
