Improvement in the CSF after perceptual learning.

(a) Pre- (dashed curve and open circles) and post-training (solid curve and circles) CSFs for amblyopic eyes with AO correction (n = 26). (b) Average improvements in CSF with AO correction (dB) as a function of pre-training amblyopic VA (logMAR) (n = 26, circles). (c) The learning effect with AO correction is maintained under the condition without AO correction for the amblyopic eyes (n = 26, pre-training CSF: dashed curve and open squares, post-training CSF: solid curve and squares). (d) The learning effect with AO correction is transferred to the untrained fellow eyes (n = 9, pre-training CSF: dashed curve and open triangles, post-training CSF: solid curve and triangles). The error bars indicate the standard errors across observers.
