Typical optic neuritis is a demyelinating inflammation of the optic nerve, often associated with multiple sclerosis and with a relatively good prognosis. A small percentage of optic neuritis cases have divergent clinical characteristics and a different underlying aetiology. These atypical cases of optic neuritis must be treated more intensively and followed up more closely in order to preserve visual function. It is important to be aware of the atypical features, so that correct assessment and treatment is initiated.
