Genetics and development of the optic chiasm [PDF]

Frontiers in Bioscience, 2008
In animals with binocular vision, retinal fibers either project across the midline or they remain on the same side of the ventral diencephalon, forming an X-shaped commissure known as the optic chiasm. The correct formation of the optic chiasm during development is essential to establish a fully functional visual system.

Paramagnetic Rim Lesions Are Associated With Trans‐Synaptic Degeneration of the Visual Pathway in Multiple Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives Retrograde trans‐synaptic degeneration (rTSD) from posterior visual pathway lesions in multiple sclerosis (MS) is characterized by hemi‐macular ganglion cell‐inner plexiform layer (GCIPL) thinning and contralateral visual field loss.

Technical note: Endoscopic resection of a dermoid cyst anchored to the anterior optic chiasm

Interdisciplinary Neurosurgery, 2014
Introduction: Supratentorial dermoid cysts arise due to the misplacement of embryonic inclusions in the vicinity of the developing neural tube up to the third week of life, when the neural groove begins to close.

Anterior interhemispheric approach for microsurgical resection of an optic chiasm cavernoma

Interdisciplinary Neurosurgery, 2020
Background: Optic chiasm cavernoma (OCC) is an uncommon lesion. A limited number of case reports have been published. We report a case of OCC with 48 months follow-up after complete microsurgical resection. Additionally, we provide a pertinent literature

Zebrafish Slit2 and Slit3 Act Together to Regulate Retinal Axon Crossing at the Midline

Journal of Developmental Biology, 2022
Slit-Robo signaling regulates midline crossing of commissural axons in different systems. In zebrafish, all retinofugal axons cross at the optic chiasm to innervate the contralateral tectum.
