A follow-up study on 50 adults investigated the impact of PM2.5 exposure on ocular health. Samples were collected before and after the high PM2.5 season, utilizing data from the Thung Satok monitoring station. Participants completed an ocular symptom questionnaire, and PM2.5 concentrations were measured using HPLC-FLD. Logistic regression indicated that PM2.5 exposure significantly increased the risk of ocular redness (adjusted OR: 12.39), watering (adjusted OR: 2.56), and dryness (adjusted OR: 5.06), with symptoms worsening during high PM2.5 seasons. An exposure-response relationship was noted, with lymphocyte counts correlating to ocular symptoms. The study concludes that higher PM2.5 exposure significantly alters ocular surfaces.
