Spatial analysis between particulate matter and emergency room visits for conjunctivitis and keratitis

BACKGROUND: The concentration of particulate matter in the air varies depending on the region because it is lightweight and generated from a variety of sources. To assess the relationship between particulate matter and eye disease, this study analyzes the concentration data obtained from spatial analysis of particulate matter and emergency visit data. METHODS: concentration were mapped for comparison, and their relationship was examined using scatter plot, regression analysis, and the independent sample t-test. RESULTS: and the number of patients showed a dose-response relationship. When the concentrations of other air polluta9nts were controlled for, the numbers of conjunctivitis and keratitis patients were 0.04 per 1000 ER patients and 0.10 per 1000 ER patients, respectively. CONCLUSION: is associated with the prevalence of conjunctivitis and keratitis, measures to reduce particulate matter through environmental methods are needed.
