The optic chiasm is an X-shaped structure formed by the crossing of the optic nerves in the brain. The optic nerve connects the brain to the eye. To biologists, the optic chiasm is thought to be a ...

Optic nerve gliomas develop anywhere between the optic nerve head next to the retina and the optic chiasm, where the left and right optic nerves partially cross. The optic nerves transmit visual ...

Optic nerve hypoplasia occurs when the optic nerve is underdeveloped. Learn more about this illness, including what to look for, what to expect, and more.

The optic chiasm senses light and controls daily body rhythms. It is the first place in the brain the optic nerve touches. It took the severed nerve cells about six weeks to regrow to the optic ...

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. CNS injuries ...

Optic nerve gliomas arise from astrocytes and form low-grade masses similar to pilocytic astrocytomas of the inferior fossa. 12 More than 90% of optic nerve gliomas occur in persons younger than ...

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. In ...

An optic nerve that has an injury cannot be fixed, so usually, if there is vision loss from ischemic optic neuropathy, it is permanent. Those with badly damaged optic nerves usually can still see ...
