Definition and causes
Optic nerve runs from the eye to the brain and send information about what the eye sees. This information is then sent quickly to record the image in the brain immediately after the light frames retina. If the optic nerve is exposed to an inflammation, it would not be able to send images as quickly as usual. If inflammation is severe, it may perhaps do not send pictures at all.
Inflammation is usually caused by the body's own immune system attacks the nerve protective fat. This is also the fat that provides for the rapid dissemination of information, rather like insulation of wires. That is when the following symptoms.
Symptoms of inflammation of the optic nerve
The sight becomes blurred or disappearseither in a part of the visual field, or the entire eye. In light cases surveyed do not disappear completely, but only weakened. This is experienced only as aafblegning of the color red. Survey deficiency can occur suddenly (overtime), and vision may be gone within a few days. There may also bepain at the movement of the eye.

Complications of inflammation in the optic nerve
In about. half of the cases is inflammation of the optic nerve first signs of multiple sclerosis. In the second half of the cases are no cause for the disease. Often found characters in the past inflammation of the optic nerve in people with multiple sclerosis, without the label has something for the disease. An MRI scan of the brain might be. say something about this risk.
Treatment of inflammation of the optic nerve
Inflammation of the optic nerve treated as a rule do not. Binyrebark-given hormone in the blood speeds up or recovery, but the doses must be so great that there are many side effects. Most cases of inflammation of the optic nerve will also go down by themselves after weeks to months, and the survey will come back. However, there is increased risk of developing the disease again, if necessary. in the opposite eye.
