The Neurological Pupil index, or NPi, is an algorithm developed by NeurOptics, Inc., that removes subjectivity from the pupillary evaluation. A patient's pupil measurement (including variables such as size, latency, constriction velocity, dilation velocity, etc.) is obtained using a pupillometer, and the measurement is compared against a normative model of pupil reaction to light and ...
Middle: Captured videos are ready for viewing, and the Pupil Reactivity (PuRe) score values are displayed. Right: The PuRe score quantifies pupil reactivity on a scale 0–5 (0, non-reactive pupil; 0–3, abnormal/“sluggish” response; 3–5, normal/brisk response). The app provides other pupillometry parameters, such as initial pupil size ...
Pupillometer, also spelled pupilometer, is a medical device intended to measure by reflected light the size of the pupil of the eye. [1] In addition to measuring pupil size, current automated pupillometers may also be able to characterize pupillary light reflex .
This type of instrument, which is commonly referred to as a pupillometer, albeit incorrectly, [11] may also be used to verify PD measurements taken with a PD stick. [12] As an alternative to having PD measured by an ECP, a variety of web and mobile (Android and iOS) apps are now widely available. Web apps are used by a variety of online sellers ...
