Figure 1. Scatterplots showing the association between serum neurofilament light chain (sNfL) and peripapillary retinal nerve fiber layer thickness (pRNFLT) in nonoptic neuritis (n-ON) (A) eyes (top left) and in (C) relapsing-remitting MS (RRMS) n-ON (bottom left), and the association between sNfL and macular ganglion cell and inner plexiform layer thickness (mGCIP), in (B) MS n-ON eyes (top right), and in (D) RRMS n-ON (bottom right).
