Automatic Retinal Image Analyzer (ARIA): A Glimpse of Our Health

Project Description

Division of Biostatistics, Jockey Club School of Public Health and Primary Care


Retinal vessels are the only visible vessels accessible by simple fundus photography. Retinal vessels have the same embryo origin and histological structure with cerebral vessels. It provides us a convenient way to assess the cardiovascular condition and reflects pathological change caused by diabetes and hypertension.

ARIA, developed by CUHK, is an algorithm built on the cloud internet platform. Standard retinal images can be transmitted through internet to server installed with the computer algorithm, which uses advanced biostatistics method to read pixel-by-pixel the retinal images and analyze these pixels to come up with measurements on exudates, hemorrhages, new vessels etc.. Finally, an overall rating will be given on several different diseases, which include: Diabetic Retinopathy (DR), Age-related Macular Degeneration (AMD) and Cardiovascular Diseases such as Stroke.

Uniqueness and Competitive Advantages:

  1. Fully automatic
  2. No specialist needed
  3. Non-invasive
  4. No radiation
  5. No side effects
  6. Fast
  7. Accurate
  8. Can be done as frequently as one likes
  9. Convenient



ARIA is fast and easy to use:

Step 1 – Capture image

Operator can use a widely available general fundus camera to capture the retinal image, which usually takes less than 5 minutes.

Step 2 – Upload image

A personal computer with wireless internet is connected to the fundus camera. Captured images will be encrypted and transferred to a cloud server platform for analysis and reporting.
Step 3 – Analysis

ARIA automatically analyzes the uploaded fundus photo without any human intervention. The analysis process takes less than one minute.

Step 4 – Report

A report will be sent back to the site within minutes. The results will be stored in the main server so that subjects, doctors and other authorized person can access them anytime and anywhere.
