Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: Patients with clinical suspicion of NO who must perform an MRI for the diagnosis of NO. A control group will also be set up to compare the visual functional networks of patients with NO with those of a sample of subjects free from NO.

Who may be able to join

  • Patients over 18 years of age
  • Clinical suspicion of optic neuritis
  • Benefiting from an MRI for exploration of optic neuritis
  • Affiliate or beneficiary of a social security scheme
  • Having received informed information about the study and having given their express consent to participate in the study

Who cannot join

  • Contraindication to absolute or relative MRI (in particular, pregnant or breastfeeding women)
  • History of amblyopia
  • Any pre-existing pathology leading to a decrease in vision (e.g. retinitis pigmentosa, AMD, etc.)

About this study

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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The ophthalmological functional recovery will be assessed by measuring the low contrast visual acuity on the Early Treatment Diabetic Retinopathy study scale (ETDRS scale).

    ETDRS charts presents a serie of 70 letters. The visual acuity letter score is equal to the total number of letters read correctly at 4.0 m. The score ranged to 20/10 (best visual acuity) to 20/20 000 (worst visual acuity).

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

An observational study of Neuritis, run by Fondation Ophtalmologique Adolphe de Rothschild at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 5 Jan 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The ophthalmological functional recovery will be assessed by measuring the low contrast visual acuity on the Early Treatment Diabetic Retinopathy study scale (ETDRS scale). (time frame: 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Jan 2026.
