Consensual pupillary light reflex in the pigmented rat [PDF]
Vision Research, 1989 We measured the pupillary light reflex (PLR) in 5 pigmented, Long Evans rats (under urethan sedation) in three conditions: direct stimulation, consensual stimulation, and a control condition designed to measure the effects of stray light. The average constriction (maximal amplitude) produced by a ganzfeld stimulus delivering 1.6 log quanta absorbed per

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 ...

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 ...
