We evaluated a diabetic retinopathy screening program in a community health center using single images taken with a nonmydriatic retinal camera and primary care clinicians trained to read retinal images. METHODS This study was conducted from 2001 to 2004 in a multisite community health center staffed by family physicians, advanced practice nurses, and physician’s assistants. The clinic serves a primarily low-income, Hispanic population. Clinic clinicians were trained to read the retinal photographs. All images were overread by an ophthalmologist. Patients were referred to eye care specialists for severe diabetic retinopathy, unknown or other abnormality, or inadequate photographs. We analyzed agreement between the clinicians and the ophthalmologist in recognizing diabetic retinopathy and in determining which patients needed referral. We also analyzed overall screening rates based on clinic access to the camera. RESULTS One thousand forty diabetic patients were screened for diabetic retinopathy at the health center. One hundred thirteen (10.9%) were found to have diabetic retinopathy, 46 severe enough to warrant referral to an ophthalmologist. The clinicians failed to refer 35 (10.2%) of the 344 patients the ophthalmologist believed needed referral. Most cases of missed referral were due to failure to recognize an inadequate photograph or for abnormalities other than diabetic retinopathy. Screening rates were better in the clinic with a permanent camera. CONCLUSIONS Primary care clinicians trained to read single images from a retinal camera have acceptable accuracy in screening for diabetic retinopathy. Further training may be necessary to recognize other common abnormalities.
