Visual field defects of optic neuritis in neuromyelitis optica compared with multiple sclerosis
Background Neuromyelitis optica (NMO) is an inflammatory demyelinating disease that predominantly affects the optic nerves and the spinal cord, and is possibly mediated by an immune mechanism distinct from that of multiple sclerosis (MS). Central scotoma
