Diabetic retinopathy (DR) is the most frequent microvascular complication of diabetes mellitus (DM). DR remains a leading cause of blindness, currently accounting for 4.8% of the world's 37 million blindness cases. DR is one of the critical preventable causes of blindness. In Bangladesh, the number of studies reporting the prevalence and risk factors of DR in type 2 DM (T2DM) is limited. We conducted this cross-sectional study in a tertiary hospital in Bangladesh from March 2017 to August 2019 among 200 patients with T2DM for the presence and severity of DR by using color fundus photography in a dilated pupil. The diagnosis and grading of DR were made using the Early Treatment of Diabetic Retinopathy Study (ETDRS) Chart. Out of 200 subjects with T2DM, 35.5% had DR; the frequencies of NPDR and PDR were 19.0% and 16.5%, respectively. The mean age, diabetes duration, FPG, HbA1c, TG, TC, LDL-C, and serum creatinine were statistically higher, and eGFR was lower in the study subjects with DR than those without DR; BMI and HDL-C were indifferent in the two groups. The frequencies of males, subjects having monthly income of 10,000 Bangladeshi Taka (BDT) or more, smokers, hypertensives, and subjects having uncontrolled diabetes (HbA1c ≥7%), were higher in the DR group than the no DR group. Higher age (≥50 years), higher monthly income (≥10,000 BDT), urban residence, smoking, uncontrolled diabetes, and high LDL-C (≥100mg/dL) were found to be independent risk factors of DR in the study subjects. A large-scale nationwide study is needed to find out the actual prevalence of DR in Bangladesh. |
