Improvements in brain structure and function in cataract patients after visual restoration. Six months after cataract surgery, the GM volumes of the following regions were increased to various extents: 1-fusiform (L) (BA20/36, t = 4·928), 2-frontal. Inf. Orb (R) (BA38/47, t = 6·433), 3-frontal. Inf. Orb (L) (BA47, t = 6·062), 4-frontal. Med. Orb (L) (BA10, t = 5·317), 5-anterior cingulate gyrus (R) (BA9/32, t = 6·395), 6-middle frontal gyrus (L) (BA6/8/9, t = 6·395), 7-middle frontal gyrus (R) (BA6/8/9, t = 5·393), 8-middle cingulate gyrus (R) (BA31, t = 5·020), 9-precentral gyrus (L) (BA6, t = 5·429), 10-precentral gyrus (R) (BA4, t = 4·960), 11-postcentral gyrus (L) (BA4, t = 4·600), 13-calcarine (R) (BA18/30, t = 5·055), 14-calcarine (L) (BA18/19/30, t = 5·052) and 15-superior temporal gyrus (L) (BA21/22, t = 6·159). The fALFF of the 12-superior parietal lobule (L) (BA17/19, t = 4·566) was increased after surgery, whereas the fALFF of the 16-brainstem (t = −3·923) was decreased. Notes: The sizes of the spots represent the degree of quantitative changes; GM, grey matter; fALFF, the fractional amplitude of low-frequency fluctuations; frontal. Inf. Orb, inferior orbitofrontal cortex; frontal. Med. Orb, medial orbitofrontal cortex; R, right; L, left.
