Overview
The Rothschild Foundation A Hospital follows a cohort of approximately 300 patients with hereditary retinal dystrophy. These patients are followed in ophthalmology consultation every year. In order to plan the MRI on the day of the annual consultation and to avoid additional travel for patients, patients will be informed of the study before the consultation (transmission of an information letter and the information note from study). If patients agree to participate in the study, rMRI will be scheduled. During the follow-up ophthalmologic consultation, after checking the inclusion and non-inclusion criteria, the study information will be repeated, and patients who still agree to participate will sign the study consent.
