Physiological measurements in amblyopic macaques. (A) Eye dominance distributions from 5 populations of macaque monkeys raised either normally or with different forms of abnormal visual experience, as indicated at the top of each histogram. The normal control data and those from the anisometropic and strabismic groups are from Kiorpes et al. (61); data from the atropine-treated group are from Movshon et al. (60); data from the deprived group are from LeVay, Wiesel, and Hubel (16). (B) Comparison of interocular differences in performance as measured physiologically and behaviorally in individual amblyopic macaques. Data are represented as the ratio of performance between the amblyopic and fellow eye on each of the indicated metrics of the contrast sensitivity function. Data are from Kiorpes et al. (61) and Movshon et al. (60). Reprinted with permission from ref. 64, The Visual Neurosciences, © 2004 Massachusetts Institute of Technology.
