ABSTRACT
Background:
We present a series of patients with diabetes mellitus (DM) who attended an eye hospital in Sana, Yemen during 2004.Aim:
To determine the magnitude and risk factors of diabetic retinopathy (DR).Design:
Cross-sectional study. Materials andMethods:
Ophthalmologists assessed vision, ocular pressure, ocular media and posterior segment to note ocular manifestations among patients with DM. DR was graded by using bio-microscope and Volk lens. The prevalence and 95% confidence interval of ocular complications of DM were calculated. Risk factors of DR like age, sex, duration of diabetes and hypertension were evaluated. StatisticalAnalysis:
Univariate and multivariate analysis.Results:
Our series comprised 350 patients suffering from DM. The duration of diabetes was ≥15 years in 101 (29%) patients. Physician was treating 108 DM patients with insulin. The prevalence of DR was 55% (95% CI 49.6–60.1). The proportions of background diabetic retinopathy (BDR), preproliferative diabetic retinopathy (PPDR), proliferative diabetic retinopathy (PDR) and diabetic macular edema were 20%, 13%, 17% and 22% respectively. The prevalence of blindness among DM patients was 16%. The prevalence of cataract and glaucoma was 34.3% and 8.6%. Duration of DM was the predictor of DR. One-fifth of the patients had sight-threatening DR and needed laser treatment.Conclusions:
DR was of public health magnitude among our patients. An organized approach is recommended to address DR in the study area.
