Fixed Pupillary Light Reflex due to Peripheral Neuropathy after Liver Transplantation [PDF]
Korean Journal of Critical Care Medicine, 2015 A 46-year-old female patient was admitted to the intensive care unit (ICU) after liver transplantation. About an hour later after the ICU admission, she had no pupillary light reflex. Both pupils were also fixed at 5 mm.

PUPILLARY REFLEX AT EASE: A new instrument for the demonstration of Pupillary reflex
Indian Journal of OphthalmologyAs ophthalmologists, we often come across a lot of patients with neuro-ophthalmological disorders that show no positive examination findings except for subtle abnormalities in the pupillary light reflex. However, these subtle changes are often overlooked

Relationship between Human Pupillary Light Reflex and Circadian System Status. [PDF]
PLoS ONE, 2016 Intrinsically photosensitive retinal ganglion cells (ipRGCs), whose photopigment melanopsin has a peak of sensitivity in the short wavelength range of the spectrum, constitute a common light input pathway to the olivary pretectal nucleus (OPN), the ...

Enhanced pupillary light reflex in infancy is associated with autism diagnosis in toddlerhood [PDF]
Nature Communications, 2018 Previous studies showed that children with autism spectrum disorder (ASD) have atypicalities in the pupillary light reflex (PLR). This study uses longitudinal monitoring of infants at risk for ASD to show that PLR magnitude at 10 months of age is ...

Pupil tracks statistical regularities: behavioral and neural implications [PDF]
Journal of Integrative Neuroscience, 2020 Pupillary light reflex adjusts the amount of light reaching the retina. Recent work suggests that the brainstem pupillary light reflex pathway is controlled by the environment's internal models derived from higher-order temporal statistics.

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 ...

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 ...
