Correlation between air pollutant NO2 and dry eye disease
Journal Title: Eye Science (Yanke Xuebao) - Year 2021, Vol 36, Issue 4
Abstract
[Objective:] To investigate the correlation between NO2 levels in air pollutants and dry eye. [Methods:] The clinical data of 75 279 patients with dry eye from January 2014 to January 2018 were selected and summarized. The air quality and weather data were from the daily ambient air quality data of Xi'an Meteorological Bureau from 2014 to 2018. Environmental air pollutants NO2 was included in the analysis. All data were collected on an hourly basis. We calculated the daily average for each variable and then calculated the weekly average used in this study. All patients in this study volunteered to participate., and this study was approved by the Medical Research Ethics Committee of the First Affiliated Hospital of Nanchang University. [Results:] We found that the number of outpatient visits for dry eye was significantly correlated with NO2 levels. Our study found that people of different ages were affected by different parameter changes. The concentration of NO2 in the environment was significantly correlated with dry eyes in all age groups, and is not selective for gender. Both men and women could develop dry eyes due to different levels of NO2 in the environment. Our results showed that higher levels of environmental NO2 increased the chances of dry eyes in outpatients. By analyzing the correlation between the cumulative number of patients and the NO₂ concentration in the environment, we found that the correlation was significant. Therefore, ambient air pollution and weather changes may lead to the deterioration of dry eye. [Conclusion:] There is a significant correlation between atmospheric pollutant NO2 and dry eye disease.
