The anterior angle. Lesions that involve the anterior angle of the chiasm, the point at which the optic nerve passes into and forms the chiasm, may show a junctional scotoma (Traquair, 1949) since there is at this point separation of the crossing and uncrossed fibers.
1 Damage to the optic tract, which is behind (posterior) to the chiasm, causes loss of the entire visual field from the side opposite the damage (so if the left optic track is cut, there is a loss of vision from the entire right visual field).s a consequence, the fibers of the optic nerve are covered with myelin produced by oligodendrocytes, rather than Schwann cells of the peripheral nervous system, and are encased within the meninges. Peripheral neuropathies like Guillain-Barre barrÃ© syndrome do not affect the optic. nerve
