The Effect and the Mechanism of Comprehensive Treatment on the Ocular Surface and the Visual Quality of Online Teachers with a Mild-to-Moderate Dry Eye Condition During the Early Phase of Coronavirus Disease 2019.

Objective To investigate the effect of comprehensive treatment on ocular surface function and the visual quality of online teachers with a mild-to-moderate dry eye condition during the early phase of coronavirus disease 2019 (COVID-19). Methods Secondary school online teachers diagnosed with a mild-to-moderate dry eye disease in our outpatient clinic from February to May 2020 were enrolled in this retrospective cross-section study, and all patients received dry eye comprehensive treatment. A questionnaire survey on eye-use habits, visual quality and dry eye-related indicators was collected before and after treatment (2 and 4 weeks). The changes and the correlations between indicators before and after treatment were compared. Results A total of 30 patients (15 females and 15 males) were included. After comprehensive treatment, patients had significantly higher central tear meniscus height (TMH), non-invasive first tear film breakup time (NIBUTf) and non-invasive average tear film breakup time (NIBUTav) than those before with statistical significance (P 0.05). Conclusion Comprehensive treatment could effectively improve the symptoms and visual quality of online teachers with a mild-to-moderate dry eye condition during the early stage of COVID-19 pandemic.
