>Optic Neuritis | Johns Hopkins Medicine
Optic neuritis is a condition that affects the eye and your vision. It occurs when your optic nerve is inflamed. The optic nerve sends messages from your eyes to your brain so that you can interpret visual images. When the optic nerve is irritated and inflamed, it doesn't carry messages to the brain as well, and you can't see clearly.
