Optic neuritis has several causes. These include:
- Multiple sclerosis (MS)—most common cause
- Neuromyelitis optica (NMO, Devic’s disease)
- Autoimmune disorders, such as Systemic lupus erythematosus (SLE)
- Exposure to toxic substances—this may be associated with optic neuropathy (injury to the optic nerve)
- Some medications
In some cases, the cause of optic neuritis may be unknown.
