Figure 5

Comparisons of the logarithm contrast sensitivities against the spatial frequency of the sinusoidal grating pattern display between normal monocular viewing of the display with the better or non-amblyopic eye and foveal viewing of the green LED in the other eye (○ in A-D) and monocular viewing of the display with the better or non-amblyopic eye and foveal viewing of the green LED together with eccentric viewing of the grating display by the other eye (▴ in A-D). The percentage difference as a result of additionally viewing the eccentric display (ECC) is given for each subject. A, normal subject: ECC = +2 % (not significant). B, anisometropic amblyope: ECC = −1 % (not significant). C, esotropic amblyope with anomalous BSV: ECC = −25 % (P < 0.01). D, esotropic amblyope without BSV: ECC = −33 % (P < 0.01). The s.e.m. is smaller than the symbol size and symbols falling on the x axis denote that that spatial frequency was not detected.
