Neuromyelitis optica (NMO) is a rare disorder in children
with variable presentation. We report a 7-year-old boy who
presented with bilateral retrobulbar optic neuritis and
responded very well to treatment. He was also positive for
aquaporin 4 (AQP4) antibodies, which is part of an emerging
endophenotype within autoimmune neurological disorders
in childhood.
