Data are expressed as mean ± standard deviation (SD). One-way ANOVA was used
PACG primary angle-closure glaucoma, RDW red blood cell distribution width, 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
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)
