Abstract
To determine the frequency of diabetic retinopathy and its risk factors in diabetic patients attending the eye clinic at the University Hospital of the West Indies (UHWI). This was a prospective cohort study of diabetic outpatients attending the Eye Clinic at the UHWI. Data were collected on age, gender, type of diabetes mellitus (DM), type of diabetic retinopathy, other ocular diseases, visual acuity, blood glucose and blood pressure. There were 104 patients (208 eyes) recruited for this study. There were 58.6% (61/104) females (mean age 53.6 ± 11.9 years) and 41.4% (43/104) males (mean age 61.7 ± 12.1 years). Type II DM was present in 68.3% (56% were females) of the patients and Type I DM was present in 31.7% (69.7% were females). Most patients (66%) were compliant with their diabetic medications. The mean blood glucose was 11.4 ± 5.3 mmol/L. Elevated blood pressure (<130/80) was present in 82.7% of patients. The mean visual acuity was 20/160 (logMAR 0.95 ± 1.1). The frequency of diabetic retinopathy was 78%; 29.5% had background retinopathy, and 50.5% of eyes had proliferative diabetic retinopathy (PDR) of which 34% had tractional retinal detachments. The odds ratio of developing PDR was 1.88 (95% confidence intervals (CI): ...Continue Reading
