What Is Optic Neuritis? Optic neuritis is an inflammation of the optic nerve, a bundle of nerve fibers that carry images from your retina to your brain. Each fiber carries part of the visual information to the brain. In optic neuritis, some or all of the nerve fibers become inflamed and do not function properly, and vision becomes blurred.
Optic neuritis is an inflammation that affects the myelin lining of the optic nerve, which transmits visual stimuli to the brain. The optic nerve is actually a nerve tract of axons that originate in the ganglion cells of the retina in the back of the eye. Nerve tracts are the information pathways in the brain. The optic nerves are the only nerve tracts not located entirely within the brain. The optic nerves carry visual information from the retina to the area of the brain that recognizes vision (the occipital cortex). Optic neuritis can occur in children or adults and may involve either one or both optic nerves.
