Correlation between ipVD and MBR-T or MBR-V in various layers

	RPCP		Outer layer of retina		Choroid		Lamina cribrosa
r	P	r	P	r	P	r	P
MBR-T	0.10	0.46	0.07	0.60	0.17	0.23	0.08	0.55
MBR-V	0.20	0.16	0.01	0.93	0.17	0.23	0.15	0.31

Notes: P-values and correlation coefficients (R) were calculated by univariate regression analysis.

Abbreviations: ipVD, intra-papillary vessel density; MBR-T, tissue mean blur rate; MBR-V, vascular mean blur rate; RPCP, radial peripapillary capillary plexus.
