The accessory optic system: the fugitive visual control system in infantile strabismus.

Infantile strabismus inaugurates a constellation of dissociated eye movements that correspond to visuovestibular reflexes in lateral-eyed animals. These visual reflexes are generated by subcortical visual pathways that use binocular visual input to modulate central vestibular tone. In this article, I present evidence that the accessory optic system is uniquely suited to provide an innervational substrate for visuovestibular eye movements in humans with infantile strabismus.
