Pupillary Dilation as an Index of the Orienting Reflex
Psychophysiology, 1982ABSTRACTThe effects of tone intensity (60, 75, or 90 dB) on the amplitude and habituation of the pupillary dilation response were investigated using a between‐groups design (N = 72). Although pupillary dilation responses were elicited in all intensity conditions, neither response amplitude nor habituation was influenced by differences in stimulus ...

IN 1936 Schubert and Burian1published their discovery of the pupillary fusion reflex (Fusionreaktion), which was defined as a dilatation of the pupil with a disruption of fusion and, conversely, a constriction of the pupil with its resumption. This reflex was stated to be not evanescent but lasting.

Gamma-Movement and the Pupillary Reflex
The American Journal of Psychology, 1965Bartley 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 ...

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).

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.

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.
