Neuromyelitis Optica (NMO) is an uncommon disease in which there is inflammation in the optic nerves (optic neuritis) and the spinal cord (transverse myelitis). NMO leads to a loss of myelin, the fatty substance that surrounds nerve fibers (much like insulation), and helps nerve signals travel from cell to cell.

NewYork-Presbyterian Hospital neurologists are experts in the diagnosis of NMO and the management of patients' symptoms.
