Table 3. Locations of white matter regions with FA changes in adult strabismus.

Brain regions	Brodmann	Cluster	T	MNI coordinate
	area	size	score	x	y	z (mm)
Strabismus<Normal Control
Right middle occipital gyrus	19, 37	93	6.93	38	−70	6
Right supramarginal gyrus	40	77	5.00	52	−54	30
Left cingulate gyrus	31	26	4.05	−4	−36	38
Strabismus>Normal Control
Right inferior frontal gyrus	47	35	−3.54	58	22	6

There are several white matter regions with significantly lower FA in adult strabismus than that in normal controls by voxel-based analysis of DTI. These regions include the right middle occipital gyrus and right supramarginal gyrus. Region with increased FA in strabismus was found in the right inferior frontal gyrus.
