Associations between air pollution and daily outpatient visits for dry eye disease and the effect modification of temperature.

ABSTRACT:

Background

Dry eye disease (DED) is one of the most common ocular surface disorders caused by various contributors. Air pollutants are considered a risk factor for ocular surface diseases. We aimed to investigate the associations between air pollutants (PM_2.5, PM₁₀, NO₂, SO₂, CO and O₃) and PM_2.5 constituents and daily outpatient visits for DED, as well as the modifying effect of temperature on the associations.

Methods

Daily data on DED outpatient visits and environmental variables during 2014-2019 were collected in Hangzhou, China. Distributed lag nonlinear models (DLNM) combined with time-stratified case-crossover design were utilized to evaluate the effects of air pollutants and PM_2.5 constituen
