[Use of non-mydriatic retinography to determine the prevalence of diabetic retinopathy in diabetic patients].
OBJECTIVE
To establish the prevalence and severity of diabetic retinopathy (DR) in a sample of patients from "Health Area 3" in the Community of Madrid using non-mydriatic retinography and telemedicine.


METHODS
All patients who had their ocular fundus examined due to one of the following conditions were included in the sample: type 1 diabetes (DM1), type 2 non- insulin-dependent diabetes (DM2NID), and type 2 insulin-dependent diabetes (DM2ID). In all cases, 3-field retinographies were taken of both eyes to be evaluated for the presence of DR, and its severity, by an ophthalmologist at the hospital.


RESULTS
No DR was observed in 79% of the patients examined, 9% had a mild non-proliferative DR, 9% had a moderate non-proliferative DR, and 1% had a severe non-proliferative DR. The estimated prevalence of DR in "Health Area 3" of the Community of Madrid was thus 21%. In 12% of the examinations the retinographies were considered "low quality", thus requiring a second evaluation at hospital.


CONCLUSIONS
The use of non-mydriatic retinography and telemedicine is an adequate method for the screening of DR among the diabetic population.
