Figure 4.

Interocular difference in saccadic latency plotted versus the interocular difference in log Pelli-Robson contrast sensitivity (the ratio of sensitivities). Anisometropic observers (green circles; n = 82); strabismic observers (red symbols; n = 39); and strabismic-anisometropic observers (blue symbols; n = 85). Inset shows mean values, ± one standard error, for the nonamblyopic and amblyopic members of these three subgroups plus the mean for normal observers. The interocular difference in log Pelli-Robson contrast sensitivity does not predict the interocular difference in latency.
