[Diabetic retinopathy].

Diabetic retinopathy remains the most frequent cause of blindness in the active population of industrialized countries. However, decreased vision and blindness can efficiently be reduced by good metabolic control, yearly retinal examination since onset of diabetes from puberty onwards, and timely laser photocoagulation. Increased frequency of retinal controls, in case of retinal or general risk factors, enables to detect and to treat threatening lesions early, leading to reduction of decreased vision and blindness.
