Introducing the NPi-300 Pupillometer

Quantitative Pupil Reactivity – NPi®. 
Improve the quality of the neurological exam. 
Enhance clinical decision making and patient care.


The NeurOptics® NPi®-300 Pupillometer provides an accurate, reliable, and objective measurement of pupil size and reactivity as the Neurological Pupil index™, NPi®.

  • Manual pupillary assessment is subject to compounded sources of inaccuracies and inconsistencies and can result in as much as 39% inter-examiner variability and error.*
  • The NPi-300 Pupillometer enhances pupillary assessment to assist in detecting cerebral insult, guiding treatment, and informing prognosis.*
  • There are now over 100 peer-reviewed research articles and scientific abstracts supporting the value of pupillometry and NPi in improving the quality of the neurological exam and enhancing clinical decision-making and patient care.*
