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 ...

Understanding the effects of mild traumatic brain injury on the pupillary light reflex
Concussion, 2017 The pupillary light reflex represents an optimal visual system to investigate and exploit in the mild traumatic brain injury (mTBI) population. Static and dynamic aspects of the pupillary light reflex were investigated objectively and quantitatively in ...

Pupillary light reflex in ethambutol-induced optic neuropathy [PDF]
Scientific Reports, 2020 We evaluated changes in the pupillary light reflex (PLR) of ethambutol (EMB)-induced optic neuropathy and analyzed the correlations between PLR parameters and other structural changes in EMB-induced optic neuropathy.

A Novel Method for Measuring the Pupil Diameter and Pupillary Light Reflex of Healthy Volunteers and Patients With Intracranial Lesions Using a Newly Developed Pupilometer [PDF]
Frontiers in Medicine, 2021 Background: Physicians currently measure the pupil diameter and the pupillary light reflex with visual observations using a ruler and a traditional penlight, leading to possibly inaccurate and subjective assessments.

Pupillary light reflex of lamprey Petromyzon marinus. [PDF]
Curr Biol, 2021 The discoveries of the photopigment melanopsin and intrinsically photosensitive retinal ganglion cells (ipRGCs) have revealed novel mechanisms of light detection now known to control several kinds of non-image-forming vision, including regulation of mood, the circadian rhythm, and the pupillary light reflex (PLR). These remarkable discoveries have been

The effect of opioids on the light-off pupillary reflex
Journal of Anesthesia, Analgesia and Critical CareObjective We examined the relationship between modeled opioid concentration and quantitative pupillary measures during remifentanil infusion sequences with particular attention to the “light-off” (LO) reflex. Methods Ten volunteer subjects were recruited
