Diurnal Modulation of Pupillary Light Reflex

Light & Engineering, 2023
Pupillary light reflex is mediated by intrinsic photosensitive retinal ganglion cells (ipRGCs) and the midbrain in human brain. The cells ipRGCs are highly sensitive to blue light (~ 480 nm). In this study, we evaluated diurnal changes in chromatic sensitivity of ipRGCs by measuring pupillary light reflex.

Gamma-Movement and the Pupillary Reflex

The American Journal of Psychology, 1965
Bartley distinguished six different kinds of gamma-movement and attributed all of them to a spatio-temporal distribution of the retinal image resulting from differences in reaction-time of rods and cones and differences in intensity of stimulation from the center toward the periphery of the retina.1 He purported to discredit earlier theories which ...

VER and Pupillary Reflex

1981
Visual evoked responses and pupillary reflex have been recorded simultaneously with the automatic perimeter PERIMATIC. Results are reported from normal patients and several cases of visual pathway disturbances. These results are compared to the subjective responses obtained with the same instrument.

The pupillary light reflex pathway

Neuro-Ophthalmology, 1997
Since 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.

Saccadic suppression of the pupillary light reflex

Experimental Neurology, 1966
Abstract 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.

Pupillary light reflex in borderline diabetes mellitus

Diabetes Research and Clinical Practice, 1989
It 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 ...

Critical Duration for the Pupillary Light Reflex*

Journal of the Optical Society of America, 1969
Light reflexes of the eye pupil are measured with an infrared scanning pupillometer in response to a 74-deg field. At threshold, the pupillary system responds to stimulus energy for short flashes and stimulus magnitude for long flashes. On a plot of log-flash magnitude vs log-flash duration, the intersection of the constant-energy asymptote and the ...
