Note. n (%), Number of patients with glaucoma; %: ratio of the patients. SD = standard deviation. An independent-sample t-test (a) for age, Pearson’s chi-square test (b), and Fisher’s exact test (c) for categorical variables were used to test the difference between the AACG and N-AACG groups. AACG, acute angle-closure glaucoma; N-AACG, nonacute angle-closure glaucoma.
