Automatic Detection of Driver Impairment Based on Pupillary Light Reflex
IEEE transactions on intelligent transportation systems (Print), 2019The main objective of this paper is to determine the feasibility of designing a driver drunkenness detection system based on the dynamic analysis of a subject’s pupillary light reflex (PLR).

The pupillary light reflex as a point-of-care test for suicide risk: Preliminary results.
Psychiatry Research, 2020The pupillary light reflex (PLR) reflects physiologic arousal, and a potential point-of-care biomarker of suicide risk. We collected data from 9 healthy controls, 6 non-suicidal depressed patients, 7 with prior suicide attempts but not presently suicidal,

Neuroticism and the Effect of Stress on the Pupillary Light Reflex
Perceptual and Motor Skills, 1979The pupillary light reflex was recorded under control, stress and fatigue conditions for 30 subjects equally divided into groups low, moderate, and high in Neuroticism. The effects of stress were distinguished by a decrease in both latency and extent of pupillary constriction during the initial light stimulation trials, as well as by a greater ...

Characteristics of a Brisk or Sluggish Pupillary Light Reflex: A Nursing Perspective
Journal of Neuroscience Nursing, 2020Supplemental digital content is available in the text. ABSTRACT BACKGROUND Pupillary light reflex (PLR) has traditionally been assessed using a pen torch (light). Although the terms “brisk” or “sluggish” are often used, it is unclear what characteristics

The Pupillary Light Reflex Effects of Anesthetics and Hyperthermia
Anesthesiology, 1993The pupillary light reflex often is evaluated in the perianesthetic period to assess drug effects and brainstem function. Mild hypothermia alone or combined with isoflurane does not impair pupillary responses. Although perioperative hyperthermia is less common than hypothermia, abnormal increases in core temperature remain an important thermal ...

Response anisocoria in the pupillary light and darkness reflex
European Journal of Neuroscience, 2018AbstractThe pupil constricts or dilates in response to a luminance increase or decrease, and these transient pupillary responses are controlled by the parasympathetic and sympathetic pathways. Although pupillary responses of the two eyes are highly correlated, they are not always identical (referred to as anisocoria).

Pupillary Light Reflex Variability as a Predictor of Clinical Outcomes in Subarachnoid Hemorrhage
Journal of Neuroscience Nursing, 2019Supplemental digital content is available in the text. ABSTRACT BACKGROUND: A change in the pupillary light reflex (PLR) is a sensitive indicator for detecting expanding intracranial lesions.
