Resultados de un cribado de retinopatía diabéticaAnálisis de marcadores de riesgo

Abstract

Objective To identify risk markers for retinopathy in patients from our geographic area, and to compare them with those published in other studies. To design a screening interval strategy, taking into account these results, and compare it with intervals suggested in published studies. Material and methods Cross-sectional observational study on 383 diabetic patients with no previous retinopathy diagnosis, who were screened for diabetic retinopathy. An analysis was made on the possible association between patient factors and presence of retinopathy. Results A greater probability for finding retinopathy in diabetic patients was associated to insulin treatment in our study, with a statistical significance level of 95%. In patients with less than 10 year onset of their diabetes, only mild retinopathy without macular oedema was found. Conclusions Insulin treatment and time of onset of diabetes should be taken into account when designing efficient screening strategies for diabetic retinopathy.
