The correlation between peripapillary vessel density and glaucomatous related factors

	Peripapillary vessel density
	r	P
Age (year)	-0.213	0.181
Sex	0.092	0.569
IOP (mmHg)	-0.178	0.264*
Mean OPP (mmHg)	0.098	0.544
RNFL thickness (μm)	0.753	<0.001
VF MD (dB)	0.691	<0.001*

Unless otherwise illustrated, correlation analysis was made by using Pearson correlation test

IOP intraocular pressure, OPP ocular perfusion pressure, RNFL retinal nerve fiber layer, VF MD visual field mean deviation

^*Correlation analysis was made by using Spearman correlation test
