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 ...
The NeuroLight pupillometer (IDMED), on the other hand, provides this pupillary unrest in ambient light (PUAL) function, which is described as a consistent indicator of opioid effect and is the gold standard in this field of research.
The NeuroLight and NPi pupillometer are both device for measuring pupils but differ significantly in terms of ergonomics and functionality. The main distinction lies in the NPi’s use of a transparent eyecup that contains an electronic component for patient identification and results recording, making it unique to each patient.
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 ...
Eckhard Heinrich Hess (27 September 1916 – 21 February 1986) [1] was a German-born American psychologist and ethologist, known for his research on pupillometry and animal imprinting.

Overview of the retina photoreceptors. ipRGCs labelled at the top-right. Intrinsically photosensitive retinal ganglion cells (ipRGCs), also called photosensitive retinal ganglion cells (pRGC), or melanopsin-containing retinal ganglion cells (mRGCs), are a type of neuron in the retina of the mammalian eye.
Optogenetics is a biological technique to control the activity of neurons or other cell types with light.This is achieved by expression of light-sensitive ion channels, pumps or enzymes specifically in the target cells.
