Initial Pattern of Optic Nerve Enhancement in Korean Patients with Unilateral Optic Neuritis.

Abstract The purpose of this study was to demonstrate whether the pattern of optic nerve enhancement in magnetic resonance imaging (MRI) can help to differentiate between idiopathic optic neuritis (ON), neuromyelitis optica (NMO), and multiple sclerosis (MS) in unilateral ON.

AB  - PURPOSE: The purpose of this study was to demonstrate whether the pattern of
      optic nerve enhancement in magnetic resonance imaging (MRI) can help to
      differentiate between idiopathic optic neuritis (ON), neuromyelitis optica (NMO),
      and multiple sclerosis (MS) in unilateral ON. METHODS: An MRI of the brain and
      orbits was obtained in patients with acute unilateral ON. Patients with ON were
      divided into three groups: NMO, MS, and idiopathic ON. The length and location of
      the abnormal optic nerve enhancement were compared for ON eyes with and without
      NMO or MS. The correlation between the pattern of optic nerve enhancement and the
      outcome of visual function was analyzed. RESULTS: Of the 36 patients with ON who 
      underwent an MRI within 2 weeks of the onset, 19 were diagnosed with idiopathic
      ON, 9 with NMO, and 8 with MS. Enhancement of the optic nerve occurred in 21
      patients (58.3%) and was limited to the orbital segment in 12 patients. Neither
      the length nor the location of the optic nerve enhancement was significantly
      correlated with visual functions other than contrast sensitivity or the diagnosis
      of idiopathic ON, MS, or NMO. Patients with greater extent of optic nerve sheath 
      enhancement and more posterior segment involvement showed higher contrast
      sensitivity. CONCLUSIONS: Our data revealed that the pattern of optic nerve
      enhancement was not associated with diagnosis of idiopathic ON, NMO, or MS in
      Korean patients with unilateral ON. We believe further studies that include
      different ethnic groups will lead to a more definitive answer on this subject.
