Stroke Risk Analysis

Automatic Retinal Image Analysis (ARIA)

ARIA was developed by the Chinese University of Hong Kong. Since the blood vessels in the back of the eye (retina) are the only directly visible vessels in the whole body that share similar histological structure and pathological patterns with blood vessels in the brain (cerebral), they can provide an estimate of the cardiovascular health.

At iSight, we use ARIA to provide fast and convenient risk assessment for stroke. This technology can be used by individuals with diabetes, hypertension (high blood pressure), hypercholesteremia, and coronary heart disease.

Compared with traditional method of detecting stroke using MRI, CT scans, or angiography, ARIA can provide a risk assessment of stroke in the next five years within minutes. And this test is completely non-invasive.

ARIA involves taking a fundus photo from our digital fundus camera at iSight, then we send the photos for analysis. And the results will return to iSight within 10 minutes.
