Figure 4

Ipsilesional maximum SO muscle cross-sectional area (ipsilesional SO), size ratio of ipsilesional SO to ipsilesional IO muscle cross-sectional area (Ipsi SO/Ipsi IO), and size ratio of ipsilesional SO to contralesional IO muscle cross-sectional area (Ipsi SO/Contra IO) in subjects with clinically diagnosed SO palsy who did, or did not, exhibit SO muscle atrophy by MRI. All mean values were significantly larger in the group without SO atrophy. Statistical analyses comparing groups with versus those without atrophy were performed by Student’s t-test.
