Abstract

Objective: To estimate the prevalence of diabetic retinopathy among patients with type 2 diabetes mellitus (DM) who attended the National Center of Diabetes, Endocrinology and Genetics (NCDEG) in Jordan, and to determine the relationship between duration of DM, hyperglycemia, smoking, hypertension, age, gender, body mass index (BMI) and diabetic retinopathy.

Methods: This is a cross-sectional study that investigates a sample of 1000 diabetic patients suffering from type 2 DM who attended the NCDEG between September 2006 and January 2007. Eye examination by an ophthalmologist under adequate dilatation was performed in all patients. Socio-demographic, clinical and laboratory data were obtained. Diabetic Retinopathy was defined according to the International Clinical Diabetic Retinopathy Severity Scale adopted by American Academy of Ophthalmology (AAO) and the International Council of Ophthalmology (ICO). Statistical analysis was carried out using the Statistical Package for Social Sciences (SPSS, version 11.5).

Results: Out of 1000 patients; 51 percent were male, 49 percent were female. The mean age and duration of diabetes were 57.8 and 9.6 years, respectively. The prevalence of diabetic retinopathy in patients was 34.1 percent. Non-proliferative diabetic retinopathy was documented in 24.5 percent, while 9.6 percent had proliferative diabetic retinopathy. Duration of DM and hyperglycemia, as measured by HbA1C, were statistically significantly associated with diabetic retinopathy.

Conclusion: Diabetic retinopathy is highly prevalent among Jordanian patients with type 2 DM. Serious national efforts should be directed towards increasing primary prevention through regular ophthalmic examinations and strict glycemic control in patients with type 2 DM.
