Abstract

This paper describes a general practice based diabetic retinopathy screening service employing a technician trained in direct and indirect ophthalmoscopy and taking photographs with a Canon CR3 45 NM non-mydriatic polaroid camera analysed by a consultant ophthalmologist to provide a comparison with the screener's opinion. Prospective data is presented from the first 1050 patients screened for diabetic retinopathy in the Exeter Health Authority area. Analysis of data collected showed a prevalence of diabetic retinopathy in the screened population of 27%, 14% previously undetected with a 0.5% prevalence of sight-threatening retinopathy. There was almost complete agreement between ophthalmoscopy findings and the consultant analysis of photographs. Screening costs were calculated at 10.38 pounds per patient screened. A specially trained non-medically qualified technician can provide a good quality cost-effective screening service for diabetic retinopathy within a primary care setting.
