Note. n (%), number of patients with glaucoma; %, ratio of the patients. SD = standard deviation. The independent-sample t-test (a) and Pearson’s chi-square test (b) were used to test the difference between COVID-19 positive and COVID-19 negative groups. AACG, acute angle-closure glaucoma; N-AACG, nonacute angle-closure glaucoma.
