Portable Infrared Pupillometry
Anesthesia & Analgesia, 2015Portable infrared pupillometers provide an objective measure of pupil size and pupillary reflexes, which for most clinicians was previously only a visual impression. But despite the fact that pupillometry can uncover aspects of how the human pupil reacts to drugs and noxious stimulation, the use of pupillometry has not gained widespread use among ...

Perspectives on Psychological Science, 2012
The measurement of pupil diameter in psychology (in short, “pupillometry”) has just celebrated 50 years. The method established itself after the appearance of three seminal studies ( Hess & Polt, 1960 , 1964 ; Kahneman & Beatty, 1966 ). Since then, the method has continued to play a significant role within the field, and pupillary responses ...

Automated pupillometry in intensive care
Intensive Care Medicine, 2022Background. In critically ill patients, pupillary light reflex (PLR) is commonly used to explore brainstem dysfunction. Standard PLR assessment using a penlight is simple and inexpensive, but qualitative and prone to subjectivity. Automated pupillometry (AP) standardises the intensity, the distance from the eye, and duration of the light stimulus and ...

Validation of a Smartphone Pupillometry Application in Diagnosing Severe Traumatic Brain Injury
Journal of Neurotrauma, 2023The pupillary light reflex (PLR) is an important biomarker for the detection and management of traumatic brain injury (TBI). We investigated the performance of PupilScreen, a smartphone-based pupillometry app, in classifying healthy control subjects and ...

Artifact Management in Pupillometry
Nursing Research, 1994A detailed analysis of pupillometry data collection and handling procedures in the initial study uncovered a number of problems that threatened the integrity of the data, including improper procedures, lack of adherence to data collection rules, and inaccurate mathematical calculation of results.

Attachment is in the eye of the beholder: a pupillometry study on emotion processing
Scientific ReportsEarly attachment relationships exert lasting effects on psychophysical health across the lifespan. Limited behavioral evidence suggests that these effects stem from how individuals perceive, interpret, and respond to their environment.

Automated pupillometry in space neuroscience
Life Sciences in Space Research, 2023Modern pupillometers are automated, thereby providing an objective, accurate, and reliable evaluation of various aspects of the pupillary light reflex at precision levels that were previously unobtainable. There are many gaps in knowledge regarding pupil size and pupillary light reflex in nervous system changes related to space travel given the ...
