We report the frequency of longitudinally extensive lesions in children with first events of optic neuritis. Subjects had brain or orbit MRI within 3 months of onset and were evaluated at the University of California, San Francisco, Pediatric Multiple Sclerosis Center. Lesion length, determined by T2 hyperintensity or contrast enhancement, was blindly graded as absent, focal or longitudinally extensive (at least 2 contiguous segments of optic nerve). Of 25 subjects, 9 (36%) had longitudinally extensive optic neuritis. Extensive lesions were not associated with non\u2013multiple sclerosis versus multiple sclerosis diagnosis ( P = 1.00). No association between age and lesion extent was observed ( P = .26). Prospective studies are needed to determine if longitudinally extensive optic neuritis can predict visual outcome.<\/jats:p>","DOI":"10.1177\/0883073813520500","type":"journal-article","created":{"date-parts":[[2014,2,21]],"date-time":"2014-02-21T22:03:48Z","timestamp":1393020228000},"page":"120-123","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":11,"title":["Longitudinally
