Cranial Nerve
There are twelve different cranial nerves that emerge indirectly from the brain. Cranial nerves serve the purpose of relaying information between the brain and other body parts, mainly to and from the regions from the neck to the head. The optic nerve is among the twelve cranial nerves that transmit visual information to the brain from the retina that lays at the back of the eye CITATION Wil10 \l 1033 (Wilson, 2010).
The optic nerve can be damaged in various ways, consequently resulting to multifaceted consequences. Below is a table that analyzes common ways to damage the nerve with the respective consequences CITATION Wil10 \l 1033 (Wilson, 2010).
Ways to damage the nerve

Consequences of damage

Injury to the optic nerve as a result of edema or ischemia thus causing loss of blood supply to the nerve via the arteries that supply blood to the nerve.

Instant loss of vision

Infarction of the optic nerve or hematoma surrounding the nerve
