Abstract :

 Background and objectives: There is a gap in knowledge in Saudi literature about the prevalence of diabetic retinopathy (DR) and its risk associated factors. This cross–sectional study aimed to assess the prevalence of DR in diabetic patients and its associated risk factors. Materials and Methods: The present study analyzed data from 103 diabetic patients attending Prince Abdul–Aziz bin Majed Diabetes care centre, Madinah, KSA in the period from January to June 2015. Diagnosis of DR in the studied patients was established by ophthalmologists through history and ophthalmic examination. The data were analyzed by appropriate statistical methods, and multivariate logistic regression analyses were used to estimate the risk. Results: The prevalence of DR among the studied diabetic subjects was 16.5% (95% CI= 9.33–23.67%). The risk of DR were positively associated with patients� age > 60 years (odds ratio (OR)= 8.10; 95% confidence interval (CI)= 1.40–12.0), poor control of diabetes (OR= 17.5; 95% CI=1.65–26.93), > 5 years duration of diabetes (OR= 6.50; 95% CI= 0.60–13.69), and associated severe hypertension (OR= 4.30; 95% CI= 1.4–13.04), and to less extent type II of DM, female sex, smoking and obesity. A significant reduced risk, however, was found among married patients and those with high level of education. Conclusion: The study revealed a relatively high prevalence of DR in the studied diabetic patients. The study suggested some risk factors to influence the development of DR among the studied patients. Large sample studies are needed to confirm these findings
