Abstract
PURPOSE: Diabetes-related retinopathy is the leading cause of blindness in India. The study was carried out with the purpose of studying the association of sight-threatening diabetic retinopathy (STDR) with socioeconomic factors and demonstrating the impact of STDR on the affected individual. METHODS: A mixed methods (quantitative and qualitative) research design was used. The study participants were divided into two groups for quantitative analysis. The control group consisted of non-sight-threatening diabetic retinopathy, whereas the study group consisted of sight-threatening diabetic retinopathy. Apart from demographics, data on comorbidities, type and duration of diabetes mellitus (DM), health insurance status, and socioeconomic data were collected from each individual. A statistical test (Chi-square) was performed to study the association between socioeconomic (SE) classes and STDR. For the qualitative part, a few people were chosen. Face-to-face interviews were conducted in depth. RESULTS: A total of 207 individuals, were recruited, of which 69 had STDR and the remaining 138 had non-STDR. The incidence of STDR was high among patients with lower socioeconomic class (SEC) (upper lower and lower), and univariate analysis revealed a strong association between STDR and SEC, the presence of comorbidities, presence of health insurance, type and duration of DM, and P value <0.05. SEC, in contrast, emerged as an independent risk factor for STDR in multivariate analysis. STDR had a devastating effect on all patients interviewed. The financial impact was most likely the most severe. CONCLUSION: People with lower SEC are more likely to suffer from STDR-related vision loss. The impact of such vision loss on individuals is multifaceted, including a negative impact on social and work life, psychological well-being, and, most importantly, a significant financial impact.
