Data are expressed as mean ± standard deviation (SD). One-way ANOVA was used. The mean IOP, VCDR, and MD were the lowest in the mild PACG group, followed by the moderate and then the severe one. However, the AL was found significantly different in the female subgroup but not male subgroup regarding the three severity groups

IOP intraocular pressure, VCDR vertical cup-disc ratio, CCT central corneal thickness, AL axial length, ACD anterior chamber depth, MD mean deviation values for the visual field, MS mean sensitivity values for the visual field, PACG primary angle closure glaucoma, n the number of eyes

aP < 0.05 for the difference between mild PACG and severe PACG (one-way ANOVA with the LSD post hoc test)

bP < 0.05 for the difference between mild PACG and moderate PACG (one-way ANOVA with the LSD post hoc test)

cP < 0.05 for the difference between moderate PACG and severe PACG (one-way ANOVA with the LSD post hoc test)
