Retinal differences between multiple sclerosis and neuromyelitis optica spectrum disorder

Takeaway

  • Dysfunction of the outer retina was observed using multifocal electroretinography (mf-ERG) in individuals with multiple sclerosis (MS) but not in individuals with neuromyelitis optica spectrum disorder (NMOSD).

Why this matters

    It is well documented that damage to the inner retinal layer occurs in MS and NMOSD. The results of this study suggest that outer retinal structure abnormalities can be used to help with differentiating and diagnosing MS versus NMOSD.
