Monochromatic pupillometry in unilateral glaucoma discloses noadaptive changes subserved by the ipRGCs

Frontiers in Neurology, 2014
Purpose: to detect signs of a possible adaptive mechanism of the intrinsic photosensitive ganglion cells in unilateral glaucoma. Method: 11 patients with unilateral glaucoma, classified by automated perimetry (glaucoma: MD< 0), were studied by ...

The Normal Pupillary Light Reflex

, 2002
The normal pupillary light reflex is initiated following exposure to light. After a brief latency, both the right (solid line) and left (broken line) pupil constrict, then undergo a small amount of redilation (escape), followed by oscillations (hippus ...

Case report: Unilateral papilledema in a dog with a large suprasellar mass and suspected intracranial hypertension: insights from funduscopy, optical coherence tomography, and magnetic resonance imaging

Frontiers in Veterinary Science
A spayed, 8-year-old female Poodle, weighing 5.7 kg, was presented with the chief complaint of vision impairment. Vision assessment, including pupillary light reflexes, menace response, dazzle reflex, and maze navigation in photopic and scotopic ...

Pharmacological Isolation of Cognitive Components Influencing the Pupillary Light Reflex

Journal of Ophthalmology, 2015
Cognitive operations can be detected by reduction of the pupillary light response. Neurophysiological pathways mediating this reduction have not been distinguished.

Association between pupillary examinations and prognosis in patients with out-of-hospital cardiac arrest who underwent extracorporeal cardiopulmonary resuscitation: a retrospective multicentre cohort study

Annals of Intensive Care
Background In some cases of patients with out-of-hospital cardiac arrest (OHCA) who underwent extracorporeal cardiopulmonary resuscitation (ECPR), negative pupillary light reflex (PLR) and mydriasis upon hospital arrival serve as common early indicator ...

Modulation of physiological reflexes by pain: role of the locus coeruleus

Frontiers in Integrative Neuroscience, 2012
The locus coeruleus is activated by noxious stimuli, and this activation leads to inhibition of perceived pain. As two physiological reflexes, the acoustic startle reflex and the pupillary light reflex, are sensitive to noxious stimuli, this sensitivity,

Inhibition of the Pupillary Light Reflex by Transcranial Magnetic Stimulation

, 1996
To investigate modulation of the pupillary light reflex by visual cortex using transcranial magnetic stimulation in humans. Transcranial magnetic stimulation was applied to the occipital cranium with and without light stimulation while recording pupil ...
