(A) Altered ALFF in NAION patients in comparison with normal controls. Compared with NCs, the ALFF in patients with NAION were lower in the right insula, right inferior frontal gyrus, bilateral middle frontal gyrus and higher ALFF value in the right precuneus. (B) Correlations between the RNFL in the right eye and ALFF values in right middle frontal gyrus (n = 31; r = 0.42, P = 0.02). ALFF: Amplitude of low-frequency fluctuation; NAION: Non-arteritic anterior ischemic optic neuropathy; NCs: Normal controls; r: Pearson correlation coefficient; RMFG: Right middle frontal gyrus; RNFL: Retinal nerve fiber layer.
