ICAS Screen Based on RIC

Intracranial atherosclerosis stenosis (ICAS) is a leading cause of ischemic stroke worldwide and increase the global burden of stroke, especially in the Asian population. Compared with the other stroke subtypes, patients with ICAS had more severe stroke, stayed longer in the hospital and higher risk of recurrent ischemic events. Thus, early screening and effective intervention for intracranial atherosclerotic stenosis can improve the level of early warning and prevention of stroke, decrease the incidence and mortality of stroke, which is of vital significance. Although digital subtraction angiography (DSA), computed tomography angiography (CTA) and magnetic resonance angiography (MRA) have a high diagnostic value for ICAS, it is invasive and not available for mass population screening due to expertise, expensive cost, and poor economic performance. Potential screening tools such as transcranial doppler sonography (TCD) are promising but limited by temporal bone window quality and highly depends on operators' experience. Therefore, it is imperative to explore a novel, non-invasive, economic and complementary screening method for identifying the subjects with ICAS in mass populations such as primary health-care institutions and physical examination centers. The retina develops from the diencephalon, shares the same embryological origin, anatomic features and physiological properties with brain, including blood supply via the internal carotid artery.
