Co-occurrence of Acute Retinal Artery Occlusion and Acute Ischemic Stroke: Diffusion-Weighted Magnetic Resonance Imaging Study

Abstract

In their article, “Co-occurrence of acute retinal artery occlusion and acute ischemic stroke: Diffusion-weighted magnetic resonance imaging study,” Lee and associates recommend emergent evaluation of patients with suspected brain or retinal ischemia. 1 Lee J.

Concerning the recommendations of the American Heart Association and American Stroke Association guidelines, we admit that the referenced journals provide insufficient information. However, according to the newly proposed definition by the American Heart Association (AHA), transient neurological dysfunctions caused by retinal ischemia are considered as a transient ischemic attack (TIA) and the guideline recommends undergoing similar processes of evaluation in patients with retinal ischemia as in those with focal brain ischemia.
