Clinical and Economic Burden of Visual Impairment in an Aging Society of South Korea

Whereas the incidence of visual impairment and blindness (VI&B) is decreasing, the total number of VI&B is increasing due to the growth of elderly population. To compare the clinical and economic outcomes of patients with and without VI&B (ie, cases and controls) in Korea, a case–control study was performed using the Health Insurance Review and Assessment Service–National Patients Sample data. Cases had higher prevalence for all of the Charlson Comorbidity Index components, depression, fracture, and injury as well as eye diseases compared to age- and sex-matched controls. In regression after adjustment of concomitant diseases, cases had 2.7 times (95% confidence interval = 2.3-3.2) higher medical expenditure than controls. The results of this study confirm that patients with VI&B have significantly higher direct medical expenditures and concomitant diseases than those without VI&B and highlight the need for a public health strategy to reduce potentially avoidable costs attributed to VI&B.
