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 ...

With optic nerve involvement, as in this case, myelin oligodendrocyte glycoprotein optic neuritis should be part of the differential diagnosis.

T1-weighted coronal MRIs. Note the diffuse enlargement of both optic nerves, the optic chiasm and both optic tracts. One can easily appreciate the infiltration of these structures, especially when ...

Neuroscientists have identified a small molecule that can effectively stimulate nerve regeneration and restore visual functions after optic nerve injury.

Traumatic injury to the brain, spinal cord and optic nerve in the central nervous system (CNS) are the leading cause of disability and the second leading cause of death worldwide.

Cavernous malformations of the optic pathway are rare vascular anomalies defined by clusters of dilated, thin‐walled capillaries that may develop along the optic nerve, chiasm, or tract. These ...

A picture of the human optic nerve chiasm and associated optic nerve sheath that covers it. Purple highlights the optic nerve tissue and the white vasculature surrounding it highlights the lymphatic ...

A midline intracranial tumor often presents with a bitemporal visual field defect because of its ability to encroach or invade the optic nerve chiasm. Neuroimaging is key to determining the cause ...

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.
