NeruroLight pupillometer
Quantitative Pupillometry Index

The QPi is the score allowing a quick interpretation of the pupillary light reflex of patients.

Pupil reactivity

>> Automated Quantitative Pupillometry <<

  • Precise measurement of pupil size (miosis/mydriasis)
  • Quantitative measurement of the Quantitative Pupillary Light Reflex (QPi Score)
  • Detection of anisocoria
  • Visualisation of trends for early change detection

>> Beyond Pupil Examinations <<

  • Neurological diagnosis of critically ill patients
  • Monitoring after primary and secondary brain injuries
