Decussating axons segregate within the anterior core of the primate optic chiasm
Jonathan C Horton, Mikayla D Dilbeck, John R Economides
doi : 10.1136/bjo-2022-322235
Background The axons of ganglion cells in the nasal retina decussate at the optic chiasm. It is unclear why tumours cause more injury to crossing nasal fibres, thereby giving rise to temporal visual field loss in each eye. To address this issue, the course of fibres through the optic chiasm was examined following injection of a different fluorescent tracer into each eye of a monkey.
