In anomalous retinal correspondence (ARC), retinal points in the right and left eyes which receive stimuli from one object in space have the same visual direction despite a manifest motor deviation. The mode of cooperation of these anomalously corresponding retinal points depends on their relative eccentricity or their relative functional level. If there is a great difference, as for the most part in large angle strabismus, the retinal point with less eccentricity and better resolution will prevail, while the other will be suppressed. This leads to a second area of high resolution in the binocular visual field with a possibly irritating effect. In microtropia, anomalous corresponding retinal points have functionally different levels only in the very centre of the visual field. ARC provides in this case a binocular cooperation very similar to normal fusion. To an individually different degree, ARC can adapt to new squint angles, which makes squint surgery possible without postoperative diplopia, but a change to normal binocularity with stable interocular connections can not be achieved. ARC enables the heterotropic patient to see with both eyes simultaneously without diplopia by a regionally changing use of inhibition and anomalous fusion in the interest of the best possible perception.
在异常视网膜对应（ARC）中，尽管存在明显的运动偏差，但来自空间中一个物体的刺激所作用的右眼和左眼视网膜点具有相同的视觉方向。这些异常对应的视网膜点的协作模式取决于它们的相对偏心率或相对功能水平。如果存在很大差异，就像大多数大角度斜视那样，偏心率较小且分辨率较高的视网膜点将占主导，而另一个则会被抑制。这会在双眼视野中导致第二个高分辨率区域，可能会产生刺激作用。在微小斜视中，异常对应的视网膜点仅在视野的正中心具有功能上不同的水平。在这种情况下，ARC提供了一种与正常融合非常相似的双眼协作。ARC可以在不同程度上适应新的斜视角度，这使得斜视手术成为可能且术后不会出现复视，但无法实现具有稳定眼间连接的正常双眼视觉状态。ARC使斜视患者能够通过根据区域变化使用抑制和异常融合，以尽可能获得最佳感知的方式，双眼同时视物而不出现复视。
