[Screening for diabetic retinopathy].

Photographic screening for diabetic retinopathy has been carried out for 40 months in an Eye Department. The results are described, with particular emphasis on cost-benefit. It is shown that the procedure finances itself with a wide margin. It probably provides better control of retinopathy than traditional clinical procedures. There may thus be a potential to reduce human suffering and the cost to society of visual impairment. The screening also provides the Department with better photographic services in general.
