PupiLUX:Pupillary Light Reflex

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

— All analysis on-device — no images leave your iPhone

— PupiLUX Pro Report (PDF) with reference ranges and status indicators
