Quick answer
What is Optic neuritis?
Optic neuritis is inflammation of the optic nerve, which carries visual signals from the eye to the brain. It typically causes fairly sudden blurring or loss of vision in one eye over hours to days, often with pain that is worse on moving the eye, and colours may appear washed out.
- How it is treated: Vision usually recovers substantially over weeks to months, often without specific treatment.
- Self-care: There are no specific lifestyle measures for the episode itself, but where an associated condition such as multiple sclerosis is found, its own management and general healthy-living measures apply.
- When to seek help: Sudden loss or blurring of vision in one eye, or eye pain with reduced vision, needs urgent (same-day) assessment to find the cause.
What it is
Optic neuritis is inflammation of the optic nerve, which carries visual signals from the eye to the brain. It typically causes fairly sudden blurring or loss of vision in one eye over hours to days, often with pain that is worse on moving the eye, and colours may appear washed out. It is more common in younger adults and can occur on its own or as an early feature of, or in association with, conditions such as multiple sclerosis. Because vision changes have several causes, prompt assessment is important. Diagnosis is clinical, often with an eye and neurological examination and sometimes an MRI scan.
How it is treated
Vision usually recovers substantially over weeks to months, often without specific treatment. A course of steroids may be used to speed recovery in some cases, decided after assessment, though it does not change the final outcome for most people. Just as important is investigating for any associated condition, particularly multiple sclerosis, so that appropriate follow-up or treatment can be arranged. Because sudden vision loss has other, sometimes serious, causes, it is assessed urgently rather than waited on.

Answers
Optic neuritis: frequently asked questions
Does vision recover after optic neuritis?
For most people vision recovers substantially over weeks to months, often without specific treatment. Steroids may speed recovery in some cases but do not usually change the final outcome.
Is optic neuritis linked to multiple sclerosis?
It can be an early feature of, or associated with, multiple sclerosis, which is why assessment includes looking for an underlying cause. Not everyone with optic neuritis develops MS.
