  1. Significant values are in bold.
  2. CCT = central corneal thickness; BCVA = best-corrected visual acuity; ACD = anterior chamber depth; SE = spherical equivalent; AL = axial length; IOP = intraocular pressure; SAP = standard automated perimetry; MD = mean deviation; PSD = pattern standard deviation; VFI = visual field index; PACG = primary angle closure glaucoma; NTG = normal tension glaucoma.
  3. *Statistical significance was tested by generalized estimating equation (for continuous variables) or chi-square test (for categorical variables).
