Moderate myopia	0.282 (0.193–0.411)	0.001 †
Marked myopia	0.425 (0.292–0.620)	0.023 †
After excluding the extent of myopia
VCDR (per 0.1 larger)	2.595 (0.972–6.927)	0.001 ‡
Axial length (per mm longer)	0.796 (0.731–0.868)	0.008 ‡

MD = mean defect, OR = odds ratio, CI = confidence interval, VCDR = vertical cup-to-disk ratio.

^†Candidate risk factors included: age, gender, right/left eye, central corneal thickness, BCVA (logMAR), vertical cup-to-disk ratio, baseline IOP, mean follow-up IOP, IOP reduction, IOP reduction percentage, initial MD, follow-up period, spherical equivalent, axial length, and the extents of myopia;
