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