Optic neuritis

Overview

If you have pain in the eye and temporary loss of vision, wake up as you may be suffering from optic neuritis, an inflammation of the bundle of nerve fibers that transmit visual information to your brain from your eye. The condition is generally associated with an autoimmune disorder caused by an infection. In some people, the symptoms of optic neuritis could indicate multiple sclerosis, a disease that damages the nerves in your brain and spinal cord.If you have suffered just one episode of optic neuritis then chances are that you will recover your vision, especially with the support of steroid medications. Although the exact cause is unknown, it is believed to develop when the immune system mistakenly targets the substance (myelin) covering your optic nerve, resulting in inflammation and damage to the myelin, which helps electrical impulses travel quickly along the optic nerve, from the eye to the brain. In the brain, those electrical impulses are converted into visual information.
