Pupillometry

Neurological Monitoring

The portable NeuroLight provides an absolute measurement of the pupil size and the photomotor reflexes of patients.

Healthcare professionals have access to reproducible and precise measurements in order to establish a fast and objective assessment. The calibrated flash of light produces a controlled non-aggressive stimulation of the retina. The pupil size and reactivity are daily measurements and part of the protocol for the critically injured or ill patient. They are essential in the clinical monitoring and neurological assessment of the patient.

The NeuroLight charts the measurements taken for trend and variation analysis of the pupil size and reactivity.

NeuroLight incorporates an optical system that eliminates any calibration step before use.

Its reusable and autoclavable eyecups save any extra cost in use. Its design and the materials used provide ergonomics and absolute comfort for the patient while eliminating the influence of ambient light on measurement results.

The STA-W2 charging station makes it easy to recharge the NeuroLight at any time.

"Reliability of standard pupillometry practice in neurocritical care: an observational, double-blinded study"

Couret D, Boumaza D, Grisotto C, Triglia T, Pellegrini L, Ocquidant P, Bruder NJ, Velly LJ.

In critical care units, pupil examination is an important clinical parameter for patient monitoring. Current practice is to use a penlight to observe the pupillary light reflex. The result seems to be a subjective measurement, with low precision and reproducibility. Several quantitative pupillometer devices are now available, although their use is primarily restricted to the research setting. To assess whether adoption of these technologies would benefit the clinic, we compared automated quantitative pupillometry with the standard clinical pupillary examination currently used for brain-injured patients.

"Automated quantitative pupillometry for the prognostication of coma after cardiac arrest"

Suys T, Bouzat P, Marques-Vidal P, Sala N, Payen JF, Rossetti AO, Oddo M.

Sedation and therapeutic hypothermia (TH) delay neurological responses and might reduce the accuracy of clinical examination to predict outcome after cardiac arrest (CA). We examined the accuracy of quantitative pupillary light reactivity (PLR), using an automated infrared pupillometry, to predict outcome of post-CA coma in comparison to standard PLR, EEG, and somato-sensory evoked potentials (SSEP).
