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).

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 ...

Pupillary light reflex in borderline diabetes mellitus
Diabetes Research and Clinical Practice, 1989It is well known that in diabetes mellitus the early phase insulin release response to glucose becomes blunted. Besides, autonomic neuropathy develops frequently. The autonomic nerve function is related to insulin release in normal subjects. Therefore, in the present study the autonomic function was investigated in different degrees of the early phase ...

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.

The influence of iris color on the pupillary light reflex
Graefe's Archive for Clinical and Experimental Ophthalmology, 1998This study was carried out to investigate the effect of iris color on the pupillary light reflex (PLR) in normal healthy volunteers.Pupil perimetry was performed on 50 healthy volunteers with the Octopus 1-2-3 automated perimeter. Within the 30-deg visual field, 33 test locations were investigated four times. Stimulus parameters were Goldmann size V (1.

Adrenergic Mechanisms in the Pupillary Light‐Reflex Path
Acta Physiologica Scandinavica, 1964AbstractOn the basis of the known effects of reserpine on the eye, the presence of monoaminergic mechanisms in the light‐reflex path of the rat was studied with the use of a fluorescence method for the localization of catecholamines and 5‐hydroxytryptamine at the cellular level.

The cerebellar control of the pupillary light reflex in the cat
Brain Research, 1977The effect of cerebellar lesions upon the pupillary light reflex was examined in anesthetized cats. The pupillary response elicited by a step and sinusoidally modulated light stimulus was used. In acute cerebellectomized cats, the high frequency cutoff of the frequency response of the pupillary reflex was moved to a lower level after cerebellar lesions.

Pupillary light reflex and circadian synchronization in the elderly
PsyCh Journal, 2017AbstractMost elderly lack a synchronized circadian rhythm and often cannot benefit from light therapy. Non‐visual effects of light are mediated through intrinsic photosensitive retinal ganglion cells (ipRGCs). With chromatic pupillometry, the functionality of ipRGCs and their functional circuit in the brain can be tested.
