Rectal gyrus	47	0	21	−24	−4.8377
Left inferior frontal gyrus	18	−51	27	−9	−4.9389
Right inferior temporal gyrus	37	48	−42	−33	−4.8183
Right superior temporal gyrus	49	66	−30	15	−5.2981
POAG > NC
Right angular	29	39	−54	33	4.3347

Note: GRF correction voxel Z>3.090232, cluster P＜0.05, cluster size 18 voxels.

FCS: functional connectivity strength; CBF: cerebral blood flow; POAG: primary open angle glaucoma; NC: normal controls; GRF: Gaussian random field theory.
