Predictive Value of the Optic Nerve Involvement in Clinically Isolated Syndrome
Evaluation of the Predictive Value of the Optic Nerve Involvement at the Stage of Clinically Isolated Syndrome, for the Diagnosis of Clinically Definite Multiple Sclerosis and the Delay of Second Relapses' Occurrence
About This Trial
Optic neuritis (ON) represents around 30% of clinical presentation of clinically isolated syndrome (CIS). Asymptomatic optic nerve involvement is very frequent in all stage of multiple sclerosis (MS) disease including the CIS. However, optic nerve is still not part of MS diagnosis criteria. The main objective of our regional and multicenter study is to evaluate the prognostic value of optic nerve involvement at the earliest clinical stage of MS (=CIS) for the diagnosis of clinically definite MS (2nd clinical relapse) and the delay until the 2nd relapse.

Optic nerve MRI sequence
Systematic optic nerve MRI sequence during the CIS diagnosis work-up. This sequence is not done systematically and not recommended for now (except in case of acute ON). The interventional nature of the study remains minimal
