Understanding the Relationship Between the Neurologic Pupil Index and Constriction Velocity Values

Understanding the Relationship Between the Neurologic Pupil Index and Constriction Velocity Values

The pupillary light reflex (PLR) describes the response when light hits the retina and sends a signal (cranial nerve II) to the Edinger-Westphal Nucleus which via cranial nerve III results in pupillary constriction. The Neurological Pupil index TM (NPi) and pupil constriction velocity (CV) are two d...

Zusammenfassung:The pupillary light reflex (PLR) describes the response when light hits the retina and sends a signal (cranial nerve II) to the Edinger-Westphal Nucleus which via cranial nerve III results in pupillary constriction. The Neurological Pupil index TM (NPi) and pupil constriction velocity (CV) are two distinct variables that can be observed and measured using a pupillometer. We examine NPi and CV in 27,462 pupil readings (1,617 subjects). NPi values
