Prevalence of diabetic retinopathy in Peruvian patients with type 2 diabetes: results of a hospital-based retinal telescreening program.
Objective. To estimate the prevalence of diabetic retinopathy (DR) in patients with type 2 diabetes and to determine any association with clinical factors. Methods. This hospital-based screening project was designed to prospectively detect the presence of DR in patients with type 2 diabetes by gradi...

To estimate the prevalence of diabetic retinopathy (DR) in patients with type 2 diabetes and to determine any association with clinical factors. Methods. This hospital-based screening project was designed to prospectively detect the presence of DR in patients with type 2 diabetes by grading images acquired with a digital retinal camera. Results. Of 1 311 patients screened, appropriate retinal images were obtained in 1 222 subjects (93.2%). DR was detected in 282 patients (23.1%) [95% confidence interval (CI): 20.71--25.44]; 249 patients (20.4%) (95% CI: 18.1--22.6) had nonproliferative DR and 33 (2.7%) (95% CI: 1.8--3.6) had proliferative DR. In 32 patients (11.3%), DR was unilateral. The frequency of DR was the same in both sexes. Prevalence of blindness was twice as frequent in patients with DR as in those without it (9.4% and 4.6%, respectively) (P = 0.001). The frequency of DR at diagnosis was 3.5% and it increased with the duration of diabetes. DR was more frequent in patients with arterial hypertension, macrovascular or microvascular complications, and hemoglobin A1c (HbA1c) ≥ 7.0% and in those treated with insulin or sulfonylureas. It was less prevalent in those with HbA1c < 7.0%, with greater body mass index, and who had been treated with metformin. Conclusions. The prevalence of DR in these patients with type 2 diabetes was 23.1%. Nonproliferative retinopathy accounted for 77.0% of cases. Although less prevalent than in a previous report, it doubled the frequency of blindness in the people affected. A national screening DR program should be considered in order to detect this prevalent condition early and treat it in a timely fashion. pubtype: Academic Journal doctype: Article src: R language: English refInfo: copyright: @attributes: flag: N holdings: @attributes: islocal: N |
