In neuroanatomy, the optic tract (from Latin tractus opticus) is a part of the visual system in the brain.

Each of these tracts is derived from a combination of temporal and nasal retinal fibers from each eye that corresponds to one half of the visual field.

[6] Lesions in the optic tract correspond to visual field loss on the left or right half of the vertical midline, also known as homonymous hemianopsia.

Peripheral prism expanders and vision restitution therapy may be employed in patients with visual field loss resultant of permanent optic tract damage.

[medical citation needed] In certain split-brain patients who have undergone a corpus callosotomy to treat severe epilepsy, the information from one optic tract does not get transmitted to both hemispheres.
