Optic Neuritis

Optic neuritis is an inflammation of the optic nerve, the nerve that carries visual information from the eye to the brain. It can cause sudden, painless vision loss in one eye.

The exact cause of optic neuritis is unknown, but it is thought to be an autoimmune condition. This means that the body's immune system attacks the optic nerve by mistake.

If you have questions about optic neuritis, it is important to seek care with an eye care professional.
