Regions of the cerebral GM where NTG patients showed significant volume difference with respect to NC and POAG at FSL‐VBM analysis across the whole brain

GM regions of the visual cortex (local maxima)	Side	MNI X, Y, Z (mm)	Cluster size (voxel no.)	P‐value
Volume: NTG < NC
TOFC	R	32,–54,–10	46	0.002
Volume: NTG > POAG
LOC	L	−38,–80,2	34	<0.001
GM regions outside the visual cortex (local maxima)
Volume: NTG < NC
IFG	L	−46,24,14	88	0.003
Precentral gyrus	L	−44,–8,46	224	0.001

GM regions are ordered according to increasing Z values. See text for details (including values of GM volumes) and abbreviations.
