The optic tract is a part of the visual system in the brain.

It is a continuation of the optic nerve and runs from the optic chiasm (where half of the information from each eye crosses sides, and half stays on the same side) to the lateral geniculate nucleus.

Right vs. left

The relationships of the retinal fibers to the optic tracts are as follows:

|- 
| right optic tract  

|- 
| left optic tract  

Pathology

A lesion in the left optic tract will cause right-sided homonomous hemianopsia.
