MRI Versus Ocular UltraSonography for a Non Contact Evaluation of Ocular Layers

Sponsor

Fondation Ophtalmologique Adolphe de Rothschild

Enrollment

30 participants

Start Date

Jan 23, 2024

Study Type

OBSERVATIONAL

Conditions

Describe Ultrasound Matches and Disagreements Ocular and MRI

Summary

D0: inclusion visit * information * Realization of the ocular ultrasound (care) * Collection of consent * Realization of high resolution MRI with injection of contrast product (duration of 30 minutes) For the realization of the MRI, the contrast product used is the gadobutrol. The dose, the lowest allowing an enhancement of sufficient contrast for diagnostic purposes (0.1 mmol/kg body mass body), is administered as a bolus intravenously in the lying patient. The MRI examination can begin immediately after injection. The patient should be monitored for at least half an hour after this, the majority of undesirable effects occurring at the during this period. The indication of ocular ultrasound and ophthalmological follow-up of the patient up to 1 month after inclusion will be collected at from their medical records.

  • Absolute or relative contraindication to the injection of gadolinium (history of an allergic reaction to a product of contrast, bronchial asthma, allergic terrain, renal failure with serum creatinine clearance <30 mL/min)
  • Patient benefiting from a legal protection measure
