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.

[Pupillometry as a method for monitoring of pupillary light reflex in ICU patients].
Voprosy neirokhirurgii imeni N N Burdenko, 2021This review is devoted to the modern method of monitoring of pupil diameter and reactivity in patients with acute brain injury. The authors present complete data on diagnostic and prognostic capabilities of automated infrared pupillometry, which should ...

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.

The Pupillary Light-Off Reflex in Acute Disorders of Consciousness
Neurocritical CareIn intensive care patients with disorders of consciousness, the pupillary light reflex is a measure of pupillary parasympathetic function. By contrast, the pupillary light-off reflex leads to pupil dilation in response to an abrupt change from light to ...

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.

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.

The pupillary light reflex in migraine
Ophthalmic and Physiological Optics, 2005AbstractThe 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. There was a significant increase in the absolute

Diurnal Modulation of Pupillary Light Reflex
Light & Engineering, 2023Pupillary 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.
