[Optic neuritis in children]

Abstract

Study of 40 children who presented a first episode of idiopathic optic neuritis. A mean follow-up of more than 8 years revealed only 15% of multiple sclerosis. This frequency is much lower than in adults. The visual outcome is also better. Significant factors are: absence of papilloedema, unilaterality, recurrence, HLA B7 and DR2, oligoclonal cerebrospinal fluid, anomalies of the VEPs.
