What indoor environmental factors can affect dry eye?

Editor's Note Due to the widespread use of electronic products, as well as people's poor eye environment and behavioral habits, the incidence of dry eye is increasing year by year, which has attracted great attention from ophthalmologists. In addition to exploring the diagnosis and treatment of dry eye, many scholars have also carried out research on the relationship between environmental factors and dry eye. However, previous studies mostly focused on the relationship between outdoor environment and dry eye, and lacked the relationship between indoor environment and dry eye. This information is complemented by an article published in JAMA Ophthalmol by Amy Huang et al. Why study the link between indoor environment and dry eye? Most environmental studies related to dry eye have studied the link between the outdoor environment and dry eye. Few studies have focused on the impact of indoor environment (such as particulate matter, etc.) on dry eye, but humans spend 90% of their time indoors. It is necessary to supplement the research data on the influence of indoor environment on dry eye. It is not that there is no research in this area in the past, but the existing research is to evaluate indoor conditions in the form of self-report. In order to make up for this deficiency, Amy Huang et al. A study of the correlation between humidity and particulate matter amount, count) and symptoms and signs of dry eye. Study Design and Evaluation Metrics The sample of this prospective cross-sectional study was obtained from the Miami Veterans Medical Center in 97 veterans who were evaluated for dry eye indicators in the clinic and then at home using a handheld particle counter for one week. Evaluation of environmental indicators. Dry eye symptoms were assessed by standardized questionnaires, dry eye signs were assessed by standard examinations, and indoor environmental indicators included temperature, humidity, and particulate matter quality and count. The data analysis period was from October 19, 2017 to August 30, 2018. RESULTS: Of the 97 participants analyzed, 81 (84%) were male, with a mean age of 58.2 years, with moderate dry eye symptoms and a mean Ocular Surface Disease Index (OSDI) score of 31.2. Humidity was positively correlated with the severity of dry eye manifestations, possibly because higher humidity affects microbial growth and particle size and quality. Increased exposure to particulate matter was associated with more severe dry eye manifestations when humidity was adjusted. Summary of Correlation Coefficients Between Indoor Environment and Dry Eye Indicators During Aerocet Count Measurements This study concluded through objective measurement and assessment that indoor environment is associated with dry eye. Unlike outdoor air pollution, one can improve the indoor environment by regulating humidity, temperature, and the quality and count of air particles, which provides a potential treatment option for improving symptoms and signs of dry eye. Although this study did not provide direct causal evidence that this option improves dry eye, the fact that interventions such as improved ventilation and HEPA filters have been shown to reduce asthma symptoms and reduce asthma hospital admissions Research in this area is worthy of further in-depth exploration, and future research may continue to explore whether interventions are beneficial in improving symptoms and signs of dry eye.
