ARIA-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.


  • Non-invasive

  • Fast result

  • Accurate

  • No radiation

  • No side effects

ARIA- cognitive health risk


What does Automatic Retinal Image Analysis (ARIA) do for me?

Provide fast and convenient risk assessment of cognitive health.

Use by those who are health conscious and would benefit from an initial cognitive health risk assessment.

No blood sample is needed.

How does ARIA works?

1.Capture retinal images with a fundus camera.

2.Upload encrypted images for analysis and reporting.

3.Analysis of images by ARIA.

4.Report ready for review.

The entire process take just 5-10min

ARIA-eWMH was developed to assess the risk of severe age-related white matter hyperintensities (ARWMH) in the brain based on automatic retinal images analysis (ARIA), using cerebral magnetic resonance imaging (MRI) as gold standard and achieved more than 90% sensitivity and specificity.

Who would benefit from ARIA-eWMH?

Age 50 or above and, Those who have not diagnosed of dementia or mild cognitive impairment and,

Willing to learn or establish a healthy lifestyle and,

Able to obtain a set of clear retinal images on both eyes for the analysis.
