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 ...
In 2019, the first smartphone based pupillometer was released as an accurate and economical way to determine pupil size and dynamic response objectively. [8] However, another study has shown the necessary use of an opaque eyecup as pupillary light reflex is affected by ambient light. [ 7 ]
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 ...
Outside the United States, the standard chart distance is 6 metres (20 ft), and normal acuity is designated "6/6". Other acuities are expressed as ratios with a numerator of 6. Some clinics do not have 6-metre eye lanes available, and either a half-size chart subtending the same angles at 3 metres (9.8 ft), or a reversed chart projected and ...

Dog anatomy comprises the anatomical study of the visible parts of the body of a domestic dog. Details of structures vary tremendously from breed to breed, more than in any other animal species, wild or domesticated, [ 1 ] as dogs are highly variable in height and weight.
