Statistical analysis
VF
REFRACTIVE ERROR, PGA
All statistical analyses were performed using SPSS (SPSS for Windows, V. 26.0). Parameters with the data that followed a normal distribution were presented as standard ± deviation. Parameters with a skewed distribution of their data were presented as median and quartiles. The data with normal distribution were examined using the Shapiro–Wilk’s W test. Parameters of uncorrected visual acuity (UCVA), best-corrected visual acuity (BCVA), CCT, vertical cup-to-disc ratio, refractive error, RNFL thickness, disc area, VF MD, or VF pattern standard deviation (PSD) had skewed distributed, so a nonparametric Mann–Whitney test was used to compare these parameters. Pearson's chi-squared test was used to analyze categorical variables such as gender and TM pigmental grading. 24-h IOP characteristics (mean, peak, and fluctuation of IOP) obtained at diagnosis and different follow-up times were analyzed using a 2-way repeated-measures analysis of variance (ANOVA) with a group (SLT group and PGA group) as a between-subjects factor and different follow-up times as within-subjects factor. Greenhouse Geisser correction was applied whenever the sphericity assumption was violated. Multivariate analysis of variance process and Bonferroni correction for multiple comparisons were used to detect significant differences between groups and different measurement times for each group.
