Retinal morphology in eyes without previous ON.

Results of retinal OCT outcomes of NMOSD and MS patients’ eyes without history of optic neuritis and healthy controls; GEE results showing the differences between NMOSD-NON and MS-NON to healthy controls. Outer retinal layers include outer plexiform layer, outer nuclear layer and inner photoreceptor layer segments.Abbreviations: NMOSD: neuromyelitis optica spectrum disorder; MS: multiple sclerosis; NON: eyes without history of optic neuritis; HC: healthy controls; OCT: optical coherence tomography; p/mRNFL: peripapillary and macular retinal nerve fiber layer; TMV: total macular volume; GCL: ganglion cell layer; IPL: inner plexiform layer; INL: inner nuclear layer; SD: standard deviation; Min: minimum; Max: maximum; B: coefficient estimate from generalized estimating equation models (GEE), SE: standard error from GEE coefficient estimates.
