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 .
