An Innovative Technique to Evaluate Quantitative Pupillary Light Reflex by Dynamic Pupillometry using Infrared Videography [PDF]
Journal of Clinical and Diagnostic Research, 2019 Introduction: An innovative approach was designed to quantify the pupillary light reflex using infrared and white light illumination. This method is convenient to detect pupil edges, area and the diameter of pupil contour recorded in different ambient ...

RdgB2 is required for dim-light input into intrinsically photosensitive retinal ganglion cells. [PDF]
, 2015 A subset of retinal ganglion cells is intrinsically photosensitive (ipRGCs) and contributes directly to the pupillary light reflex and circadian photoentrainment under bright-light conditions.

The pupillary light reflex distinguishes between circadian and non-circadian delayed sleep phase disorder (DSPD) phenotypes in young adults. [PDF]
PLoS ONE, 2018 This study investigated the utility of the pupillary light reflex as a method of differentiating DSPD patients with delayed melatonin timing relative to desired/required sleep time (circadian type) and those with non-delayed melatonin timing (non ...

Estimation of operators’ fatigue using optical methods for determination of pupil activity
International Journal of Occupational Medicine and Environmental Health, 2015 Introduction The purpose of this study was to develop and initially validate an objective, yet quick, method for assessment of human fatigue. This aim can be achieved by the use of an optical, non-contact method of analysis of pupil activity.

Cortical modulation of pupillary function: systematic review [PDF]
PeerJ, 2019 Background The pupillary light reflex is the main mechanism that regulates the pupillary diameter; it is controlled by the autonomic system and mediated by subcortical pathways.

The Pupillary Light Reflex as a Biomarker of Concussion [PDF]
Life, 2021 The size of our pupils changes continuously in response to variations in ambient light levels, a process known as the pupillary light reflex (PLR). The PLR is not a simple reflex as its function is modulated by cognitive brain function and any long-term changes in brain function secondary to injury should cause a change in the parameters of the PLR. We
