Quantitative assessments of pupillary light reflexes in hospital-onset unresponsiveness
Background Patients who develop hospital-onset unresponsiveness should be promptly managed in order to avoid clinical deterioration. Pupillary examination through pupillary light reflex is the gold standard method in the initial evaluation of ...

The Pupillary Light Reflex in Borderline Diabetics
Computerized IR videopupillography, using an open-loop photic stimulator, was used to compare the reflexes of borderline diabetics with overt non-insulin-dependent diabetics and with age- and sex-matched non-diabetic healthy controls. The patients were all male, aged 41–59 years.

Pupillary Size and Light Reflex in Premature Infants [PDF]
The authors examined pupillary light reflexes to both red and blue stimuli using infrared video-pupillography in premature infants. Pupillary light reflexes were obtained in response to 470 nm blue and 635 nm red stimuli with varying intensities of 10 cd/m2 and 100 cd/m2. Red stimuli did not evoke a pupillary response in premature infants.

Regulatory effects of blood constituents on the function and metabolism of the cat brain in perfusion ezperiments. Brain perfusion with artificial blood containing low molecular dextran and amino acids [PDF]
As a link in a series of studies on the effects of blood constituents on the brain function by means of brain perfusion, we used four kinds of artificial blood; namely, the blood containing a low molecular dextran, one containing glutamic acid, one ...

Quantitative Assessment of the Canine Pupillary Light Reflex [PDF]
To develop instrumentation and methods for thorough quantitative assessment of the pupillary light reflex (PLR) in dogs under varying stimulus conditions.The PLR was recorded in normal Dachshunds using a custom system allowing full user control over stimulus intensity, color, and duration.

Consensual pupillary light reflex in the pigmented rat [PDF]
We measured the pupillary light reflex (PLR) in 5 pigmented, Long Evans rats (under urethan sedation) in three conditions: direct stimulation, consensual stimulation, and a control condition designed to measure the effects of stray light. The average constriction (maximal amplitude) produced by a ganzfeld stimulus delivering 1.6 log quanta absorbed per

Pupil light reflex evoked by light-emitting diode and computer screen: methodology and association with need for recovery in daily life [PDF]
Objectives: Pupil light reflex (PLR) has been widely used as a method for evaluating parasympathetic activity. The first aim of the present study is to develop a PLR measurement using a computer screen set-up and compare its results with the PLR ...

Reduced pupillary light reflexes in diabetic autonomic neuropathy [PDF]
Infrared television pupillometry was performed in 71 healthy and 66 insulin-treated diabetic subjects. Resting pupil diameter and the amplitude of the reflex response to standard light flashes were measured in background darkness. In the healthy subjects with small pupils (less than 6 mm) the size of the light reflex was found to depend on the diameter

ABSTRACT Neuromyelitis Optica Spectrum Disorder (NMOSD) is a chronic autoimmune neuroinflammatory disease, typically characterized by antibodies against aquaporin 4 (AQP4‐IgG) or myelin oligodendrocyte glycoprotein (MOG‐IgG). Simultaneous seropositivity for both antibodies in a single patient is exceedingly rare.
