Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

When patients arrive in the waiting room of the MRI department, patients will be given the briefing note explaining the purpose of the study and how it is going. During the consultation, the radiologist will check the inclusion and non-inclusion criteria, and will take the time to answer all of the patient's questions about the study. If the patient agrees to participate in the research, the investigating doctor will obtain his consent.

The MRI examination will be performed on a 3T multi-parametric MRI. Compared to the standard protocol, patients will benefit from an additional sequence of f-mRI, called resting state, and performed before injection of gadolinium contrast agent.

A consultation with an ophthalmologist will also be carried out the same day, at the Adolphe de Rothschild Foundation. During this visit, an OCT examination (optical coherence tomography), a visual field as well as the measurement of visual acuity will be carried out, in accordance with the treatment usually practiced at the Adolphe de Rothschild Foundation.

The subjects of the control group who agreed to participate will benefit from an MRI examination which will include, in addition to the sequences planned for these patients according to their indications, the two non-injected sequences which will be performed on patients with suspected NO.

The possible existence of visual problems in the subjects of the control group will also be asked to them by interrogation. No eye exams or follow-up visits are planned, and control group participation will end after the MRI scan.

Patients with NO will be seen in consultation by an ophthalmologist during a follow-up visit approximately 6 months after diagnosis. During this consultation, an OCT, a visual field and the measurement of visual acuity will be performed. This visit and the examinations carried out correspond to the usual care of patients suffering from NO and followed at the Adolphe de Rothschild Foundation Hospital.
