We studied OCT in subjects with MS of varying disease durations and with no exposure to DMTs to test the hypothesis that in untreated MS, RNFLt loss occurs both over the course of disease and in parallel with corticospinal tract dysfunction reflecting CNS neurodegeneration.
To our knowledge, such regrowth through the injured corticospinal tract has not previously been documented in the scientific literature.
