Dr. Noon HEART

Retinal-based cardiovascular 
risk assessment for earlier prevention

Clinically validated algorithm

CACS-aligned risk output

Three-level risk stratification

Predict & prevent

Detect cardiovascular risk early, when intervention can change lives

Cardiovascular risk often remains hidden until symptoms or acute events occur. For over 150 years, clinicians have recognised that the retina can reveal early signs of cardiovascular disease.

Dr. Noon HEART uses advanced AI to analyse subtle vascular patterns within standard retinal images, translating these biological signals into measurable cardiovascular risk indicators.

By identifying microvascular changes linked to cardiovascular disease before symptoms appear, Dr. Noon supports earlier triage, prevention planning, and timely clinical decision-making across routine care and screening settings.

Ocular signs of CVD

Retinal blood vessel changes

Ocular cholesterol deposits

Optic disc swelling

Diabetic retinopathy

Retinal vein occlusion

Validated cardiovascular risk stratification (CACS-predicted)

Built on clinically validated algorithms, Dr. Noon HEART draws on published evidence for deep learning models that predict CACS from retinal photographs to enable cardiovascular risk stratification. It supports more actionable risk assessment, with clearer separation into low, moderate, and high-risk groups to guide prevention and follow-up planning.

The Heart Score (CACS-aligned)

Dr. Noon HEART outputs a CACS-aligned heart risk score and places each patient into a clear risk band. This makes the result fast to interpret in-clinic and easy to use for triage, patient discussion, and next-step planning.

Output at a glance

AI-powered retinal screening for CVD risk detection

CVD risk summary

A clear snapshot of cardiovascular risk from the retinal scan, including key context to support a fast, confident interpretation.

Risk stratification

A CACS-aligned result that categorises risk (Low / Moderate / High) and shows age-group context, making it easier to triage quickly and explain results to patients.

Clinical recommendations

Guidance to support prevention planning and next steps, including risk-factor prompts and follow-up direction where appropriate.
