Description ackground:Diabetic retinopathy (DR) is the fourth leading cause of blindness and is a major contributor to visual impairment after cataract, glaucoma and age-related macular degeneration. Globally, 55% of patients with diabetes are likely to suffer from DR.Aim: To determine the prevalence and risk factors associated with DR amongst type II diabetic patients.Setting: The study was conducted at a non-governmental eye clinic between March and December 2017 in the eThekwini district of KwaZulu-Natal.Methods: Patients’ demographic and clinical data were obtained through randomised systematic sampling from the medical records of 298 patients. Univariate analysis followed by multivariate logistical analysis was used to test the associations.Results: In all, 42% of the sampled patients had DR, with 98% (122 patients) displaying DR in both eyes. The mean age of DR patients was 64 years (standard deviation [SD]: 9.34), with a female (n = 97) predominance. Patients with diabetes for 10 years (odds ratio [OR]: 2.53; 95% confidence interval [CI]: 1.39–4.62), comorbidity with hypertension (OR: 7.43; 95% CI: 1.57–35.28), and presence of cardiovascular diseases (OR: 4.3; 95% CI: 2.49–7.44) were significant risk factors for DR, whilst an elevated cholesterol level showed an increased but non-significant risk.Conclusion: Diabetic retinopathy was higher in this study than the global estimated prevalence. Lifestyle diseases and its associated modifiable risk factors are important contributors to the development of DR. A holistic approach towards diabetes, which includes primary prevention and aggressive management and control of hypertension, diabetes, elevated cholesterol, and cardiovascular diseases, is required to reduce the incidence of diabetes retinopathy.
