title: Cortical oscillopsia without nystagmus, an isolated symptom of neuromyelitis optica spectrum disorder with anti-aquaporin 4 antibody.
abstract: Neuromyelitis optica (NMO), mainly affecting optic nerve and spinal cord, can also manifest diverse ocular symptoms due to brain abnormalities. We present a cortical oscillopsia without nystagmus or head tremor in a patient with neuromyelitis optica spectrum disorder (NMOSD) with anti-aquaporin 4 antibody. This rare ocular manifestation, which is easily underestimated owing to absence of the typical nystagmus, can be an initial manifestation of NMOSD.
