This analysis included only perimetric glaucoma (n = 164). * Variables that were significantly associated with optic disc tilt ratio were considered confounding factors and were included in the multivariable model. Statistically significant values are shown in bold. OR = odds ratio; CI = confidence interval; CRVT = central retinal vessel trunk; IOP = intraocular pressure; SEQ = spherical equivalent; AXL = axial length; CCT = central corneal thickness; RNFLT = retinal nerve fiber layer thickness; MD = mean deviation; PSD = pattern standard deviation.
