We investigated the possibility that the spatial imprecision of amblyopic eyes can be accounted for by the relative insensitivity to contrast that has been documented for these eyes. Thresholds for the discrimination of spatial misalignment, a measure of spatial uncertainty, were determined for three amblyopes and one normal for targets ranging in contrast from detection threshold to 99%. We found that spatial uncertainty was greater in amblyopic eyes than non-amblyopic eyes for targets equally above contrast threshold, and when the targets were presented at threshold contrast to the nonamblyopic eyes and at 99% contrast to the amblyopic eyes. Our results fail to support the possibility that the spatial imprecision of amblyopic eyes can, in general, be attributed to reduced contrast sensitivity. Different neural abnormalities are presumed to limit amblyopes' performance on different spatial tasks.
