Figure 1. Pre-training (baseline) correlations with interocular suppression.

(A). The relationship between pre-training IOR and pre-training AE visual acuity. Green symbols and red symbols show data for anisometropic and strabismic amblyopes respectively. The lines show linear regression fits to the data (green – anisometropic; red – strabismic; gray –all amblyopes). The gray vertical lines at abscissa values of 0 and 1 represent complete suppression and no suppression respectively. (B). The relationship between pre-training IOR and pre-training stereo sensitivity (1/stereo threshold in arc sec). Note that many strabismic amblyopes had no stereovision prior to training, hence some of the red symbols overlap on the figure. Blue arrows along the ordinate show the upper and lower limits of the test at 20 (top arrow) and 400 arc sec (lower arrow) respectively. The asterisks indicate significance level. * = p < 0.05; ** = p < 0.01.
