Visual acuity (VA) of EAE mice (n = 8) from baseline, pre-onset (time 1 of eye 2), onset (time 1 of eye 1 and time 2 of eye 2), and post-onset (time 2 of eye 1). Eye 1 = filled symbols; eye 2 = open symbols. The dotted line indicates VA = 0.25 c/d, which was the threshold of defined onset of optic neuritis. The results indicated that there was no visual acuity difference between eye 1 and eye 2 at time 2 (p = 0.15)
