What is optic neuritis?
Also known as: ON.
The optic nerve is the nerve pathway that connects the eye to the brain, sending visual messages to the brain for interpretation. Optic neuritis is an inflammation of the optic nerve, which becomes swollen, doesn’t function normally and results in loss of vision. It can occur in one or both eyes.
