The optic nerve is the nerve that transmits visual information from the retina to the brain. The optic nerve is composed of retinal ganglion cell axons and support cells. It leaves the orbit (eye) via ...

Automated perimetry demonstrated bitemporal hemianopic defects (Figure 1). Contrast-enhanced magnetic resonance imaging (MRI) of the brain with attention to the optic chiasm revealed a 3.2-cm sellar ...

Using an injectable peptide—a small piece of a larger protein—the team managed to get nerve cells in the severed optic nerves of mice to regrow from the damaged area all the way to the optic chiasm in ...

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 ...
