The optic nerve is also called Cranial Nerve II (CN II) or the second Cranial Nerve. It is located at the back of the eye and is responsible for transmitting visual information. The eyes work like the windows to the world with the brain processing the visual information transferred. This is made possible by electric impulses.
The optic nerve can be damaged easily like other parts of the human body. This can be because of trauma, eye disease, shock, injury, radiation, and toxins. Optic nerve damage is also possible because of diseases of the central nervous system.

Common Causes for Optic Nerve Damage
Optic nerve can be damaged due to the diseases of the brain, eye, and the central nervous system. It may happen because of shock, injury, trauma, and overexposure to radiation as well.
Other diseases, such as Leber Hereditary Optic Neuropathy, Anterior Ischemic Optic Neuropathy, Optic Nerve Head Drusen, Optic Neuritis, Multiple Sclerosis, Optic Neuropathy, Glaucoma, and Optic Nerve Hypoplasia may also damage the optic nerve.
Optic Neuritis is an inflammatory condition that causes swelling in the optic nerve. This condition is usually accompanied by other diseases, such as Multiple Sclerosis. The nerve fibers become affected because the disease causes communication issues between the body and the brain.
Optic Neuropathy is caused when there is damage to the optic nerve that results in the loss of vision. A common occurrence with this condition is the loss of color.
Glaucoma refers to a set of eye conditions which result in optic nerve damage. The intraocular pressure builds up in glaucoma that affects the optic nerve. The nerve eventually gets damaged because of the buildup of pressure and may even lead to blindness.
Optic Nerve Damage Symptoms
Many people experience tremendous pain because of optic nerve damage. People with this condition may also lose their vision. This is because the optic nerve links the eyes to the brain. Another common occurrence is loss of color vision. People tend to suffer from partial loss of color vision.
It is possible for loss of visual perception to occur as well. This is true when the damage to the optic nerve is severe.
Other symptoms of optic nerve damage include:
- Distorted vision
- Decline in vision field
- Eye inflammation
- Permanent or temporary loss of vision
Weakness of the limbs and numbness in the extremities are other symptoms. However, these are rare symptoms and may be linked to a neurological disorder.
