BACKGROUND: Since December 2022, China has eliminated the compulsory nucleic acid screening, which led to a new pandemic of Omicron. We observed a surge of primary angle-closure glaucoma (PACG) at a largest tertiary hospital in Shanghai. We evaluated the potential relationship between the infection of Omicron and the occurrence of PACG. METHODS: In this retrospective cross-sectional study, we identified 41 patients diagnosed with PACG from 523 individuals registered in ophthalmic emergency from December 2022 to January 2023. We compared the proportion of PACG patients in all the patients registered at the ophthalmic emergency department in the corresponding period (December and January) from 2018 to 2023. RESULTS: The proportion of PACG patients rose to 6.74% and 9.13%, nearly a five-fold increase compared to the previous 1.90%. The proportion of PACG patients throughout 2022 also increased in the recent 2 months. All PACG patients in our center from Dec. 21st 2022 to Jan. 27th 2023 had positive nucleic acid tests at their initial visits. The peak of glaucoma came around Dec. 27th 2022, while the peak of the internal medicine emergency came around Jan. 5th 2023. CONCLUSIONS: The behavior pattern of the infected people and anxiety mood would induce the PACG attack. Some ophthalmic advice should be added to the Chinese treatment guidelines for COVID-19. Also, a shallow anterior chamber and narrow angle need to be ruled out when necessary. Further studies on larger populations are needed to explore the relationship between PACG and Covid.
