Macular nasal fibers in the chiasm travel in which direction?

Explanation:
Signals from the nasal retina cross at the optic chiasm and then become part of the contralateral optic tract, which runs toward the brain to reach the lateral geniculate nucleus. So the macular nasal fibers travel in a posterior direction as they pass through the chiasm and onward.
