[Abstract] Objective To study the changes of percentage fluctuation amplitude (PerAF) in patients with primary angle-closure glaucoma (PACG) at rest using resting-state functional magnetic resonance imaging (rs-fMRI) technique.Materials and Methods A total of 31 cases of PACG patients diagnosed in the ophthalmology department of Jiangxi Provincial People's Hospital were included. During the same period, 31 sex, age, and duration of education-matched healthy controls (HC) were included in the control group. Whole-brain rs-fMRI scans were performed on each subject to collect PerAF signals. One-sample t-test and two-sample t-test were used to compare PerAF data across and between groups, respectively.Results Compared with HC group, subjects in the PACG patient group had significantly lower PerAF in the left supraparietal gyrus (t=-3.9421, P<0.001), orbital (t=-3.4619, P<0.001), left orbital median frontal gyrus (t=-3.6709, P<0.001), bilateral right median frontal gyrus (t=-3.8257, P<0.001), right inferior frontal gyrus deltoid (t=-3.6708, t=-4.0375, P<0.001); left supramarginal gyrus (t=-3.9570, P<0.001), inferior parietal marginal angular gyrus (t=-3.8230, t=-3.8730, P<0.001), right superior parietal gyrus (t=-4.4581, P<0.001), postcentral gyrus (t=-3.7825, P<0.001), and paracentral lobule (t=-4.0816, P<0.001); right middle temporal gyrus (t=-3.8402, P<0.001); left lingual gyrus (t=-3.5758, P<0.001); left anterior cingulate and paracingulate cingulate gyrus (t=-3.4718, P<0.001), supplementary motor area (t=-3.7209, P<0.001), and right inferior cerebellar area 7b (t=-3.9479, P<0.001) (P<0.001 at voxel level, P<0.05 at cluster level, Gaussian random field corrected).Conclusions Patients with PACG have abnormal PerAF values in multiple brain regions involving primary and higher visual cortex and brain regions associated with visual, emotional, and cognitive regulation. |
