Clinical factors affecting pupillary light reflex parameters: a single‐centre, cross‐sectional study
Ophthalmic & physiological optics, 2021To evaluate the effects of stimulus intensity, aging, sex, smoking and eye symmetry on pupillary light reflex (PLR) parameters.

The pupillary light reflex in migraine
Ophthalmic and Physiological Optics, 2005Abstract The literature suggests that there may be pupil size and response abnormalities in migraine headache sufferers. We used an infra‐red pupillometer to measure dynamic pupil responses to light in 20 migraine sufferers (during non‐headache periods) and 16 non‐migraine age and gender matched controls.

Lateralization of Pupillary Light Reflex Parameters
Klinische Neurophysiologie, 2004The aim of this study was to determine differing reactions of the left and right eyes with regard to pupillary light reflex (PLR) parameters.All together 90 healthy subjects were included. In the first test series, 34 subjects were investigated on both eyes (left eye was tested first, three tests per day and one reliability test).

Multisensory signals inhibit pupillary light reflex: Evidence from pupil oscillation.
Psychophysiology, 2021Multisensory integration, which enhances stimulus saliency at the early stage of the processing hierarchy, has been recently shown to produce a larger pupil size than its unisensory constituents.

An impaired pupillary light reflex indices in Orbital Apex Syndrome - A rare case report.
Journal Francais d'Ophtalmologie, 2021BACKGROUND The clinical presentation of reduced pupillary responses in orbital apex syndrome is currently not well understood clinically. The pupillary light reflex (PLR) is determined using dynamic pupillometry.

Saccadic suppression of the pupillary light reflex
Experimental Neurology, 1966Abstract The visual threshold is known to be elevated by as much as one or two log units just before and during both voluntary and involuntary saccadic eye movements (saccadic suppression). Experiments were carried out to discover whether or not the direct pupillary reflex is suppressed in association with saccadic suppression.

Current Opinion in Ophthalmology, 1995
A wealth of new information has recently come to light concerning the pupillary response to various types of visual input. Much of this information is recent, and has either been published in the last year, is in press, or has just been reported at meetings.

QUANTITATIVE PUPILLARY LIGHT REFLEX
Archives of Neurology And Psychiatry, 1928The instrument here presented is one that measures accurately the intensity of light, designated in candle power, and is intended as an aid in determining quantitatively the pupillary response to light. In is an improvement on a similar instrument, containing only a hand battery, which was exhibited to the Section on Ophthalmology of the College of ...

The pupillary light reflex pathway
Neuro-Ophthalmology, 1997Since Wernicke1 publicized the matter in the 1880s, it has been considered practically a ‘law of nature’ that the pupillary light reflex pathway is a simple brainstem reflex.
