我们询问弱视的抑制是否可以通过正常人中描述的双眼分视掩蔽来解释，在双眼之间存在对比度阈值差异的情况下操作。本研究采用双眼分视掩蔽实验范式，探讨混合弱视组的双眼交互作用。在大多数受试者中，在考虑了双眼之间的阈值差异后，未观察到正常的分视掩蔽。我们发现，双眼功能障碍并不仅仅是作为已知的单眼丧失的结果，它取决于弱视的病因和刺激的空间频率。
We asked whether suppression in amblyopia could be accounted for by dichoptic masking as described in normals, operating in the presence of a contrast threshold difference between the two eyes. A dichoptic masking paradigm was employed to investigate binocular interaction in a mixed group of amblyopic subjects. Normal dichoptic masking was not seen after threshold differences between the two eyes were accounted for in the majority of subjects studied. We found that the binocular dysfunction did not merely follow as a consequence of the known monocular loss and that it depended upon the aetiology of the amblyopia and the spatial frequency of the stimulus.
