三维双目视觉有两个核心过程。第一种是双眼组合/求和过程，将来自两个眼睛通道的相似特征信号整合在一起，形成双眼表征。第二，双眼抑制过程，抑制眼间冲突信号或错误匹配的双眼表征以建立单一视觉。在一个或两个过程中存在内在的眼间不平衡可导致感觉眼优势（SED），与组合（SEDcombo）和/或抑制（SEDinhibition）的不平衡有关。虽然最近有很多关于SEDcombo和SEDinhibition的发现，但它们之间的关系仍然未知。我们分别用一对不同相位的二元水平正弦波光栅和垂直和水平光栅的双眼竞争刺激测量了观察者中央凹的SEDcombo和se抑制。然后，我们使用正弦光栅刺激测量水平和垂直单眼对比度阈值，使用随机点立体图测量立体阈值。SEDcombo与sedinhition之间存在很强的相关性。观察者的眼间对比阈值差异并不总是与他/她的SEDcombo和SEDinhihition一致，提示潜在失衡的部分双目起源。我们还发现立体阈值随着SEDcombo的强度和sedinhition的强度而显著增加。我们的研究结果表明，在两种不同的双眼过程中，眼间失衡有一个共同的起源，两种类型的感觉眼优势都是阻碍立体视觉的重要因素。
Two core processes underlie 3-D binocular vision. The first, a binocular combination/summation process, integrates similar feature signals from the two eye channels to form a binocular representation. The second, a binocular inhibitory process, suppresses interocular conflicting signals or falsely matched binocular representations to establish single vision. Having an intrinsic interocular imbalance within one or both processes can cause sensory eye dominance (SED), related to imbalances of combination (SEDcombo) and/or inhibition (SEDinhibition). While much has recently been revealed about SEDcombo and SEDinhibition, the relationship between them is still unknown. We measured observers' foveal SEDcombo and SEDinhibition, respectively, with a pair of dichoptic horizontal sine wave gratings with different phases and binocular rivalry stimulus with vertical and horizontal gratings. We then measured horizontal and vertical monocular contrast thresholds using sinusoidal grating stimuli, and stereo thresholds using random-dot stereograms. There exists a strong correlation between SEDcombo and SEDinhibition. An observer's interocular difference in contrast threshold was not always consistent with his/her SEDcombo and SEDinhihition, suggesting a partial binocular origin for the underlying imbalances. We also found stereo thresholds significantly increased with the magnitudes of SEDcombo, as well as with the magnitude of SEDinhibition. Our findings suggest a common origin for interocular imbalance in the two different binocular processes and that both types of sensory eye dominance are significant factors in impeding stereopsis.
