Pre and Post-arterial Recanalization Imaging of Central Retinal Artery Occlusions (CRAO) — I-RECANAL  

Magnetic Resonance Imaging Clinical Trial

Official title:
Pre and Post-arterial Recanalization Imaging of Central Retinal Artery Occlusions (CRAO)

Clinical Trial Summary

Central retinal artery occlusions (CRAO) are the equivalent of an ischemic stroke at the retinal level. They share the same risk factors and common pathology. The diagnosis of a CRAO is clinically based on the sudden occurrence of a decrease in deep visual acuity with fundamentally signs of reactive ischemia. Small studies have highlighted the value of cerebral MRI (Magnetic Resonance Imaging) in CRAO with almost 25% of ischemic strokes found on diffusion sequences and the demonstration of a correlation between anomalies in diffusion sequence and the probability of a pathology with a high risk of recurrence (carotid stenosis or emboligenic cardiopathy). But there are usually few radiological signs that allow a direct positive diagnosis of CRAO, an etiologic diagnosis or a prognosis. This descriptive study will focus on CRAO at the diagnostic and post-treatment phases in the short and medium term, in order to (i) identify imaging etiologic signs of CRAO with specific sequences from a 3 Tesla MRI, (ii) identify positive diagnostic signs of CRAO with the same specific sequences, (iii) correlate these signs with the visual prognosis one month after the CRAO.
