Pupillometry in neurocritical care
Nursing, 2022Abstract: Though pupillometer use is becoming more widespread, there is a lack of evidence on its use by nurses in the neurosurgical ICU. This article explores the use of the pupillometer among neurocritical care nurses to better understand their experience and the device's clinical utility.

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 ...

Pupillometry in clinically sleepy patients
Sleep Medicine, 2002Investigators have suggested using pupillometry to assess alertness in hypersomnolent patients. In this study we assessed hypersomnolent patients and normal volunteers by using pupillometry and examined the usefulness of this technique for the diagnosis of pathologic sleepiness in individual patients.Forty-nine patients were examined by pupillometry ...

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.

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 ...

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 ...

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 ...

A Low Cost Pupillometry Approach
International Journal of E-Health and Medical Communications, 2015The need for low-cost health monitoring is increasing with the continuous increase of the elderly population. In this context, unobtrusive audiovisual monitoring methods can be of great importance. More particularly, the diameter of the pupil is a valuable source of information, since, apart from pathological cases, it can reveal the emotional state ...

Pupillometry of Grapheme-Color Synaesthesia
Cortex, 2006Pupil diameters of color-grapheme synaesthetes were measured with an infrared eye-tracker while Stroop-like alphanumeric symbols were passively viewed. Pupils dilated more when synaesthetes viewed incongruently-colored symbols than congruently-colored symbols or symbols printed in the standard black ink.
