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 .
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 ]
An optical sensor converts light rays into electronic signals. It measures the physical quantity of light and then translates it into a form readable by an instrument. An optical sensor is generally part of a larger system that integrates a source of light, a measuring device, and the optical sensor. This is often connected to an electrical ...
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 ...
Continuous readings can be provided by wearable or adhesive thermometers but it is difficult to measure core body temperature in this way. Invasive sensors can be attached in a hospital setting such as intensive care or neonatal care. For more general use, form-factors such as arm bands and earbuds have been tried.
