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.
