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.
Within the middle cranial fossa, the optic nerves from each eye unite to form the optic chiasm. At the chiasm, fibres from the nasal (medial) half of each retina cross over, forming the optic tracts: Left optic tract â contains fibres from the left temporal (lateral) retina, and the right nasal (medial) retina.
