Diabetic retinopathy (DR) is one of the leading causes of preventable blindness in working-age adults. The aim of this study was to determine the prevalence of DR and its association with hypertension (HTN) in patients with diabetes mellitus (DM). A cross-sectional, analytical, observational study was conducted using a 2024 database from Fundación Visión, Paraguay. A total of 6,445 patients aged ≥18 years with a diagnosis of DM were included. The variables analyzed were age, sex, origin, diagnosis of HTN, allergies, and ocular pathologies (DR, cataracts, glaucoma, and macular degeneration). Statistical analysis was performed using Stata SE, applying descriptive statistics, the chi-square test, and calculation of odds ratios (OR) with 95% confidence intervals (CI). A p-value <0.05 was considered statistically significant. The general prevalence of DR was 27.51%, with a higher frequency in women (55.19%). The population's mean age was 64.56 ± 11.69 years. HTN was present in 72.92% of patients with DR, and cataracts in 52.62%. Both conditions showed a statistically significant association with DR (HTN: OR=1.8; 95% CI 1.5–2.0; cataracts: OR=1.3; 95% CI 1.1–1.4). In conclusion HTN and cataracts were significantly associated with the presence of DR. These findings highlight the importance of ophthalmological screening and comprehensive management of risk factors in patients with DM.
