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.

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).

Archives of Ophthalmology, 1943
In 1939 one of us (Lowenstein1) described a pupillary reflex which he called the "reflex to darkness." In order to elicit this reflex both eyes of the subject tested are adapted to a constant level of illumination in which darkness is a periodic stimulus.

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 ...

Monocular Blindness With Preserved Pupillary Reflexes
Archives of Neurology, 1985To the Editor. —In their article Lhermitte et al 1 failed to mention the possibility of the most likely cause of monocular failure of light perception with relatively intact pupillary reflexes, namely, a functional elaboration of what presumably was a partial visual loss due to an episode of opticneuritis in this patient.

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.

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, 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.

Critical Duration for the Pupillary Light Reflex*
Journal of the Optical Society of America, 1969Light 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 ...
