A diagnostic tool to differentiate neuromyelitis optica spectrum disorder from multiple sclerosis

Takeaway

  • The thickness of the retinal nerve fiber layer (RNFL) and the high contrast visual acuity (HCVA) were significantly different following a single attack of optic neuritis (ON) in individuals with neuromyelitis optica spectrum disorder (NMOSD) compared with multiple sclerosis (MS) in the early stage of the disease.

Why this matters

    The presentation of an episode of ON is often reported in both MS and NMOSD. The results of this study will help distinguish NMOSD from MS in the early phase of the disease by increasing the accuracy of diagnosis which could lead to early treatment.
