PupiLUX:Pupillary Light Reflex

Quantitative bilateral pupillary light reflex measurement on iPhone. On-device AI analysis. Pro Report PDF for clinical documentation. Not a diagnostic device.

PupiLUX transforms your iPhone into a quantitative pupillometer. Perform bilateral pupillary light reflex (PLR) tests in under 60 seconds — no additional hardware, no consumables, no training required.

WHAT IT MEASURES — Baseline Pupil Diameter (BPD) — Constriction Percentage (CP) — Latency (LAT) — Maximum Constriction Velocity (MCV) — Average Dilation Velocity (ADV) — 75% Recovery Time (T75) — Relative Afferent Pupillary Defect (RAPD) — Anisocoria (baseline asymmetry)

HOW IT WORKS

1. Position the iPhone rear camera facing the patient (~12 inches)
2. Voice-guided bilateral recording captures both eyes simultaneously
3. On-device analysis measures pupil dynamics frame-by-frame
4. PupiLUX Pro Report generated with reference ranges

USE CASES — Neuro-ICU: quantitative pupil monitoring between examination rounds — Emergency: rapid pupil assessment for trauma triage and documentation

KEY FEATURES — Bilateral simultaneous testing — one recording, both eyes — All analysis on-device — no images leave your iPhone — PupiLUX Pro Report (PDF) with reference ranges and status indicators — No subscription — pay per test with prepaid credits — 100 free tests on install, no card required
