Normal retinal correspondence (NRC) is a binocular condition in which both foveas work together as corresponding retinal ponts, with resultant images fused in the occipital cortex of the brain[1].
Abnormal retinal correspondence (ARC) is binocular sensory adaptation to compensate for a long-standing eye deviation (i.e. strabismus. The fovea of the straight (non-deviated) eye and non-foveal retinal point of the deviated eye work together, sometimes permitting single binocular vision[1].
