Abstract

Background and purpose: The lack of surrogates of clinical progression has limited the design of neuroprotection trials in multiple sclerosis (MS). Our aim was to study the association between time-domain optical coherence tomography measures and clinical and magnetic resonance imaging outcomes in early MS. Methods: Forty-three relapsing-remitting MS patients within 1 year of onset were followed for up to 3 years. Results: The peripapillary retinal nerve fiber layer (RNFL) decreased annually by 2 μm (95% confidence interval -3.89, -0.11; P = 0.038). The RNFL tended to be associated with normalized normal appearing white matter volume in cross-sectional (P = 0.08) and longitudinal analyses (P = 0.06). Conclusions: There is substantial RNFL loss even in very early MS. Our data suggest that retinal axonal atrophy is associated with atrophy in global white matter volume in early MS.
