The impact of prolonged face mask use on ocular surface health during COVID-19 pandemic: a clinical, and conjunctiva impression cytology study.

Publication date: Feb 12, 2024

To investigate the relationship between prolonged face mask use and ocular surface health utilizing conjunctival impression cytology, the Schirmer test, the tear break-up time (TBUT) test, and the ocular surface disease index (OSDI) questionnaire. In this cross-sectional prospective study, individuals who used face masks for at least eight hours per day for at least six months were compared to healthy volunteers who used face masks for no more than one hour per day. Each participant completed an OSDI questionnaire. The Schirmer test (under anesthesia), the TBUT test, and conjunctiva impression cytology analysis according to the Nelson classification method were performed on each participant. This study included 102 (49 male, 53 female) face mask users with an average age of 33. 29 +/- 7. 71 years and 110 (60 male, 50 female) healthy controls with an average age of 32. 96 +/- 7. 10 years (p = 0. 746). The total OSDI score was significantly higher in face mask users than the control group (25. 18 +/- 3. 54 vs 9. 46 +/- 2. 13, p
