Retinal correspondence

Retinal correspondence is a relationship between paired retinal visual cells in the two eyes. Images from an object stimulate both cells, which transmit the information to the brain, permitting a single visual impression localized in the same direction in space.

Normal retinal correspondence (NRC) is a binocular condition in which both foveas work together as corresponding retinal points, with resultant images fused in the occipital cortex of the brain.
