Prevalence and risk factors of diabetic retinopathy in rural population of Belgaum district

Abstract

BACKGROUND: Rural population is highly underprivileged in terms of access to tertiary eye care facilities. AIMS: The aim of the study was to determine the prevalence of diabetic retinopathy (DR) and associated risk factors among known diabetics in the rural population of Belgaum district. SETTINGS AND DESIGN: A cross-sectional population-based study was carried out from January 2018 to December 2018. METHODOLOGY: Three hundred and forty patients underwent a detailed ocular examination. Clinical grading was based on early treatment of DR study guidelines. Random blood sugar, blood pressure, height, weight, hemoglobin, serum creatinine, and glycated hemoglobin (HbA1c) were measured. STATISTICAL ANALYSIS: Chi-square and analysis of variance tests were used to assess risk factors. RESULTS: The prevalence of DR was found to be 23.82%. Of this, 19.11% had nonproliferative DR (PDR) and 3.53% had PDR. Nearly 1.18% had clinically significant macular edema. A statistically significant association was found between DR and duration of diabetes, HbA1c, smoking, and family history of diabetes. CONCLUSION: The significant prevalence of DR as per this study signifies the need for regular structured screening camps and the availability of basic vitreoretinal facilities at the primary level.
