Although optic neuritis is a common clinical feature of multiple MS, it is also a common feature of the “MS variant” Neuromyelitis Optica (NMO). NMO affects the eye and the spinal cord and can be more disabling than MS. Since prognosis and treatment for MS and for NMO are different, it is crucial to differentiate between these conditions. The authors found that optical coherence tomography, a diagnostic tool used to quantify the thickness of the optic nerve, can differentiate whether optic neuritis occurs in the context of MS or NMO: the optic nerve seems to be less thick in people with NMO than people with MS.
