Results are presented as mean (95% confidence interval) or count (percentage). Sex was compared using Fisher's exact test. Continuous variables were compared using two-sample t-tests (for age) or linear mixed models (for eye level data).
ALCSD, anterior lamina cribrosa surface depth VF MD, visual field mean deviation; SE, spherical equivalent; AL, axial length; IOP, intraocular pressure; CCT, central corneal thickness.
Bold P values are significant.
