[Screening for diabetic retinopathy]

Abstract

Concurrent with the increasing incidence of diabetes mellitus, the incidence of diabetic retinopathy is also rising. Timely recognition with the aid of screening, followed by laser therapy, can prevent the greater part of the resulting visual impairment and blindness. However, many patients with diabetes are not screened or not screened adequately. The necessary screening frequency is annually or biannually, depending on the degree of retinopathy and the presence of risk factors, of which glycaemic control, duration of diabetes, blood pressure, lipid profile, and race are the most important. Digital 2-field fundus photography, preferably in mydriasis, is of sufficient quality for routine screening. The impact of screening programmes can be further improved by applying the optimal method and by initiating an active implementation strategy.
