Disclaimer:
LIOR™ is currently in pre-prototype development. We are not claiming to match the capabilities of the Neuroptics NPi-300 or any existing commercial device. These research studies support the clinical value of Quantitative Pupillometry (QP) over manual assessment. LIOR™ uses a distinct logic system and user interface designed for simplicity, portability, and frontline use.
Current Renderings Gallery
Flip through the various current renderings to get an inside view of how LIOR is put together!
LIOR™ Designed with Simplicity in Mind.
LIOR™ is approximately 170 mm long end to end. There are nine individual white LED lights that represent the measured pupil size captured at baseline by the IR camera and will stay illuminated next to its appropriately sized textured black disc.
Red, Yellow and Green Reactivity LEDs
Side View of LIOR™. The White LED pupil size array is shown clearly marked 1-9 mm and the Reactivity lights are clearly visible in Green, Yellow and Red, each representing reactivity according the PLR-3 alogrithim.
Activation Button and Toggle switch
This is an exploded view of the UI; simple and straight forward, one button to activated either the flashlight function or to put the device into search mode for its designed pupillometry function.
USB and Charging Lights
LIOR™ has a USB-C charge port along with two LEDs that indicate charging status, Red indicates charging is required and Green indicates a full charge. One charge with average use can last up to 8 days! (This is an estimate in when used in pupillometer mode.)
Inside LIOR™
This exploded view of LIOR™ shows the various internal components that are integral to making the device easy to use but also incredibly accurate. The MCU, the PCB the IR camera and the Light Burst Ring are all connected for real time neurological feedback on the Pupillary Light Reflex.
IR Camera and Light Burst Ring
LIOR™ is equipped with an infrared camera that is surrounded by 10 LED lights. The lumens delivered to the patient is safe at 150 lm to prevent the aversion reflex, but strong enough to illicit the Pupillary Light Reflex in any type of ambient light. In Flashlight mode, the lumens increase to 300 lm.

NPi-300™
Larger handheld device
High cost, limited to large hospitals, specialty units
Gold-Standard accuracy with full NPi algorithm, research backed dependability
Hospital-grade, but bulky, less portable not ideal for “out of hospital” use.
Requires Training, more complex UI, and ongoing purchase of consumables.
Full NPi Scoring with 8+ parameters, excellent for trending recovery and deterioation
Large Academic Hospitals and neurocritical care ICUs and specialty Stroke Centers.
FDA approved and cleared, CE marked
Reflex™ App
Smartphone app (uses phone camera)
Low cost, but requires ongoing subscription
Variable phone cameras and lighting can limit accuracy
Dependent on User’s smartphone, not medical-grade
Simple to use app, dependant on smartphone compatibility, patient privacy difficult to maintain
Pupil size and and PLR detail, used primarily in clinic.
Concussion and Neurology Clinics, Resource limited sites. other opthamolgical clinicians.
Currently not FDA or Health Canada approved as a medical device.
How Does LIOR™ Stack Up?
LIOR™ offers objective, reliable, and confidential pupillometry in a portable, affordable device.
Neuroptics NPi-300 remains the gold standard, but its cost and bulk limit accessibility.
Reflex App is inexpensive, but lacks reliability, durability, and confidentiality safeguards.
