在交替注视下，对斜视患者视野中不同位置的光栅敏锐度、眼间抑制和双眼相互作用进行了评价。在所有情况下，斜视眼的抑制在与注视眼的中央凹对应的区域中是最强烈的，但在周边减少或不存在。在注视眼的部分周边视野中发现抑制。对于大多数受试者，双眼的单眼特性正常。对于1名受试者的强烈偏好之一的眼睛，视力和亮度检测选择性受损的慢性抑制区域的非首选的眼睛。无论当前使用哪只眼睛进行注视，受试者可用的视觉信息都来自双眼。在部分视野中，双眼有相互替代的趋势。在远周边，特别是在上半野和下半野，从2只眼睛的信号往往结合在一个双眼的深度知觉。
Grating acuity, interocular suppression and binocular interaction were evaluated at different positions in the visual field of strabismic humans with alternating fixation. In all cases, the suppression of the deviated eye was most intense in a region corresponding to the fovea of the fixating eye, but reduced or absent in the periphery. Suppression was found in part of the peripheral visual field of the fixating eye. For most subjects, the monocular properties of both eyes were normal. For 1 subject with a strong preference for 1 of the eyes, visual acuity and luminance detection were selectively impaired in the chronically suppressed regions of the non-preferred eye. Regardless of which eye was currently used for fixation, the visual information available to the subject came from both eyes. In parts of the visual field, the 2 eyes tended to replace each other. In the far periphery, and especially in the upper and lower hemifield, signals from the 2 eyes were often combined in a binocular perception of depth.
