ARIA-stroke provides real-time probability of the stroke risk before symptoms occurs. ARIA automatically analyzes in the cloud server the retinal blood vessels to infer vital information regarding vascular-related health with great confidence in a non-invasive, fast, and convenient way with a very reasonable cost. The sensitivity and specificity of the module is over 95% and has obtained USA, China and Taiwan region patents. The technology aims to make contribution to health promotion and disease prevention, and consequentially reduce healthcare expenditure to community. ARIA-stroke is suitable for health-conscious individuals aged 18 or over with no previous stroke/ TIA. We have over 20 service partners currently available in Hong Kong. Our current and potential service partners include corporate groups, facilities with evidence-based health promotion programs, health check centers, optometric shops, NGO, and health nutrition and food companies with evidence-based supplement products.
