Inflammatory optic neuritis (ON) represents a frequent clinical situation in
neurology and ophthalmology. When MRI and CSF analysis are normal, ON is
considered idiopathic with a suspected viral etiology. However, in several cases
either a recurrence or a myelitis may occur. In the first case, it is relapsing
inflammatory optic neuritis (RION) and in the second case it is neuromyelitis
optica (NMO). Nevertheless, predictive criteria of a recurrence or an extension
of the disease to spinal cord remains unknown, excepted for anti-NMO IgG
antibodies which are probably highly specific for a future evolution to NMO. In
the present paper, the authors successively present the two clinical situations
(RION and NMO) and attempt to summarize diagnostic and prognostic criteria.
