Screening for intracranial atherosclerosis using fundus imaging

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study focuses on intracranial atherosclerosis stenosis (ICAS), a major cause of ischemic stroke, particularly in the Asian population. It aims to explore the effectiveness of fundus imaging as a non-invasive screening tool for early detection of ICAS, which could lead to timely interventions and improved patient outcomes. The study will include patients who have undergone recent imaging examinations like DSA, CTA, or MRA, and will assess their ability to cooperate with follow-up fundus examinations. By identifying patients at risk, the study seeks to enhance early warning and prevention strategies for stroke.
