Case Series: Ocular Trauma Secondary to Masks during the COVID-19 Pandemic.

SIGNIFICANCE

Previously, people had only recognized the discomfort of masks, and no one had ever realized the risk of ocular trauma associated with masks. We classify the causes of injuries into two categories and emphasize the importance of using masks properly.

PURPOSE

This study aimed to characterize and classify ocular injuries caused by masks.

CASE REPORTS

With the increase in the number of masks used during the coronavirus disease 2019 pandemic, we have seen a rise in mask-related ocular injuries. This is a single-center retrospective case series of patients presenting to the Peking University Third Hospital Ophthalmology Department emergency department with ocular injuries secondary to masks from February to August 2020. Nine patients (six males, three females) were reviewed. All patients had a unilateral injury (four right eyes, five left eyes). The most frequently injured site was the cornea, which was seen in five patients. Some patients were injured in more than one area. Seven patients were injured by metal nose wires or other rigid, sharp parts of masks. The other two patients were injured by elastic mask straps.

CONCLUSIONS

Masks can cause two types of ocular injuries that may require surgical intervention. One kind is metal nose wires or other rigid, sharp parts of masks causing lacerations or abrasions. The other is recoiling elastic mask straps snapping into the eyes and causing contusions. Our report emphasizes the importance of using masks properly.
