Do inferior nasal fibers travel more anteriorly or posteriorly in the chiasm?

Explanation:
The fibers in the optic chiasm are organized by retinal quadrant along an anterior-posterior axis. The inferior retinal fibers, particularly from the nasal half, occupy the most anterior position as they decussate. Because these inferior nasal fibers are destined to cross and contribute to the contralateral tract, they pass through the chiasm in a more anterior location than fibers from other quadrants. So, inferior nasal fibers travel more anteriorly in the chiasm.
