Low Grade Glioma of the Optic Nerves, Chiasm and Tracts. T1-weighted coronal MRIs. Note the diffuse enlargement of both optic nerves, the optic chiasm and both optic tracts. One can easily appreciate ...

Dil was injected into the left retina, and RGC axons were traced to the optic chiasm. In the wild-type animal, a subset of RGC axons is repelled at the midline and to the binocular pathway (top ...

It leaves the orbit (eye) via the optic canal, running postero-medially towards the optic chiasm where there is a partial decussation (crossing) of fibers from the temporal visual fields of both eyes.

The optic chiasm and infundibulum (pituitary stalk) could not be identified on coronal or sagittal images (Figure 1). Visual field on confrontation suggested lateral field deficits ...

Williams, S. E. Ephrin-B2 and EphB1 mediate retinal axon divergence at the optic chiasm. Neuron 39 , 919–935 (2003) Article CAS Google Scholar ...

(Left) T1-weighted sagittal MRI; (Right) T1-weighted with gadolinium sagittal MRI. Note the large enhancing mass in the region of the sella that is growing up into and displacing the optic chiasm and ...

Pituitary tumors are common intracranial neoplasms that can cause significant morbidity due to hormonal dysregulation and compression of surrounding structures. Despite advancements in surgical ...

Strikingly, most of the regenerating axons of M1-treated mice reached 4mm distal to the crush site (i.e. near optic chiasm), while no regenerating axons were found in vehicle-treated control mice.

Band optic atrophy is described as a horizontal band of optic disc pallor, often associated with a contralateral optic tract lesion and bilateral hemianopic visual field defects.

When OSK was expressed in damaged retinal ganglion cells for up to 12 to 20 weeks, their axons partially regenerated, with some axons extending as far as the optic chiasm.
