Face Mask-Associated Recurrent Corneal Erosion Syndrome and Corneal Infection.

Tang, Yi Fan; Chong, Elaine W T

ABSTRACT In the current coronavirus disease 2019 (COVID-19) pandemic, important public health measures such as the utilization of face masks has been widely enforced, including community-wide mandatory face mask use. During this period, there have been observations of an increasing number of patients presenting with dry eye symptoms among regular mask users with no history of ocular surface pathology. Individuals have reported being aware of air blowing upward from the mask into their eyes that is likely to increase the evaporation of their tear film leading to ocular irritation. Although face mask use is essential in combatting the COVID-19 pandemic, it is important to recognize the potential effects it may have on ocular health. We report a case of face mask-associated ocular complication. After an initial cornea abrasion from mask use, the patient developed recurrent corneal erosion syndrome that was complicated by microbial keratitis after the enforcement of mandatory mask use in public areas.
