Optic neuritis is a broad term expressing inflammation, degeneration, or demyelination of the optic nerve. It includes:
The disc changes in papilloedema may closely resemble those of papillitis but visual acuity is reduced markedly in papillitis but not in papilloedema.
If a person has an episode of isolated, optic neuritis, confirmed by an ophthalmologist, refer them to a consultant neurologist for further assessment (1).
Diagnosis of neuromyelitis optica spectrum disorder should be made by an appropriate specialist based on established up-to-date criteria (1).
