PERERA MINIET, Elianne et al. Clinical and epidemiological behavior of diabetic retinopathy in Marianao municipality, august-november, 2007. Rev Cubana Oftalmol [online]. 2011, vol.24, n.2, pp. 287-298. ISSN 0864-2176.

Objective: To describe the clinical and epidemiological behavior of diabetic retinopathy in Marianao municipality in the period of August to November, 2007 Methods: A single-phase, descriptive and cross-sectional study of 7693 diabetic adults was carried out from August 2007 to November 2007 in Marianao municipality. The sample of 150 adults with diabetes was questioned and examined from the ophthalmological viewpoint. Additionally, funduscopy, fluorescein angiography and optical coherence tomography were performed on those patients who required so. Results: Diabetic retinopathy prevalence was 16,0 % and it was more frequent in patients aged from 55 to 64 years (20,0 %) and in patients suffering from diabetes type 1 (28,6 %). The length of time suffering from diabetes mellitus had an impact on the increased diabetic retinopathy. There was a tendency toward less severe forms of the disease, although more severity was found in patients who had had this disease for 21 years or more. About 4,7 % and 4 % of the patients presented macular diabetic edema and legal blindness respectively. Diabetic retinopathy and cataract were the most frequent causes of blindness (1,3 % both). Conclusions: The prevalence of diabetic retinopathy and blindness caused by this illness showed figures lower than those collected in previous studies. The longer the time of evolution of diabetes, the more severe forms of diabetic retinopathy and diabetic macular edema found.

Keywords : Diabetic retinopathy; non proliferative diabetic retinopathy; proliferative diabetic retinopathy; diabetic macular edema; legal blindness.
