The optic chiasm and the corpus callosum: their relationship to binocular vision in humans.

The semidecussation of the optic nerve fibers in humans serves to facilitate the motor coordination of the two eyes. The Corpus Callosum in humans serves to facilitate the integration of stimuli from opposite cerebral hemispheres. Stereopsis and motor fusion are two distinct and separate qualities of binocular vision, and each alone can indicate central and/or peripheral binocular vision. Stereopsis is not an indicator for binocular stability.
