Disparity is the depth cue that arises from the slight difference that exists between the images that both eyes receive of an object placed at different distances. When the muscles of one eye are paralyzed, the eye cannot change the point of focus, and disparity as a cue for depth perception becomes unavailable. This is because the two eyes are not seeing different images of the same object anymore, so the visual system cannot use the differences between them to infer depth information.
