Neuroanatomy, Pupillary Light Reflexes and Pathway

Excerpt

The visual (retino-thalamocortical) pathway and pupillary light reflex pathway are the two essential ways through which the eye perceives and responds to changes in the environment. Multiple relays of information processing efficiently proceed from the cornea to the brain, and any lesion in the visual or the pupillary reflex pathway may result in visual pathology.
