The AI brain.
In your pocket.
Beyond the fundus.
Inside your visual cortex.
Every finding traces back to the brain regions it would impact. You and your clinician see not just what the eye saw — but what the brain would lose.

Microvascular ischemia stops upstream signal — V1 receives fewer photoreceptor packets.
Two brains.
One vision.
Memory pattern-matches what you've seen. Cortex reasons from first principles. Together they decide.
AMD · DR · Glaucoma · Cardiovascular.
Purpose-built pathways.
OCTON runs a dedicated deep-scan pipeline for each — evidence-graded staging, imaging protocols, and a same-day referral packet if it matters. The retina reveals not just eye disease, but the silent onset of cardiovascular risk and glaucoma long before symptoms appear.
Drusen morphology, RPE changes, subretinal fluid. 5-stage classification from none to late wet.
- Home-monitoring Amsler grid guidance
- Auto-referral to macula specialist
- AREDS-2 supplementation triggers
Microaneurysms, dot-blot heme, IRMA, venous beading, DMO. Full R0–R4 severity + M (maculopathy).
- Type-1 / type-2 diabetes screening
- Anti-VEGF pathway triggers for DMO
- Same-week urgency for proliferative
OCTON reads the optic nerve head like a specialist — C:D ratio, neuroretinal rim thinning, disc haemorrhage.
- Detects pre-clinical damage silently
- Reads RNFL asymmetry OD vs OS
- Sub-mm optic disc cupping quantified
Arteriovenous ratio, arteriolar narrowing, AV nicking — mapped to 10-year MACE risk (Poplin-style DL).
- Predicts BP, smoking, HbA1c from fundus
- Flags hypertensive retinopathy stages
- 10-yr major-adverse-cardiac-event risk score
Reasoning grounded in peer-reviewed neuroscience and ophthalmology.
OCTON's Hippocampus module performs fast pattern encoding; its Neocortex module performs deep, schema-aware reasoning. This is a direct implementation of the complementary-learning-systems framework that has dominated memory neuroscience for three decades. The retinal AI literature establishes smartphone-grade fundus screening for sight-threatening and systemic disease.

OCTON AI is a screening companion — it does not replace formal clinical evaluation. All findings should be confirmed by a licensed ophthalmologist. Citations are provided for transparency; clinical decisions should be made in accordance with your local standard of care.
