PUPILLARY REFLEX AT EASE: A new instrument for the demonstration of Pupillary reflex [PDF]
Indian Journal of OphthalmologyAs ophthalmologists, we often come across a lot of patients with neuro-ophthalmological disorders that show no positive examination findings except for subtle abnormalities in the pupillary light reflex. However, these subtle changes are often overlooked

Sonographic Consensual Pupillary Reflex [PDF]
Western Journal of Emergency Medicine, 2012 Patients suffering from severe orbital trauma are at risk for numerous complications, including orbital compartment syndromes. This can result in an afferent pupillary defect, which must be evaluated for on physical examination.

The effect of opioids on the light-off pupillary reflex [PDF]
Journal of Anesthesia, Analgesia and Critical CareObjective We examined the relationship between modeled opioid concentration and quantitative pupillary measures during remifentanil infusion sequences with particular attention to the “light-off” (LO) reflex. Methods Ten volunteer subjects were recruited

Quantitative assessments of pupillary light reflexes in neurocritically ill patients [PDF]
Journal of Neurocritical Care, 2022 The pupillary light reflex is a component of bedside neurological examinations in neurological intensive care units (neuroICUs). A quantitative pupillometer provides a non-invasive and objective pupil reactivity parameter clinically significant for ...

Pupil tracks statistical regularities: behavioral and neural implications [PDF]
Journal of Integrative Neuroscience, 2020 Pupillary light reflex adjusts the amount of light reaching the retina. Recent work suggests that the brainstem pupillary light reflex pathway is controlled by the environment's internal models derived from higher-order temporal statistics.

Gaze-contingent flicker pupil perimetry detects scotomas in patients with cerebral visual impairments or glaucoma [PDF]
, 2018 The pupillary light reflex is weaker for stimuli presented inside as compared to outside absolute scotomas. Pupillograph perimetry could thus be an objective measure of impaired visual processing.

Fixed Pupillary Light Reflex due to Peripheral Neuropathy after Liver Transplantation [PDF]
Korean Journal of Critical Care Medicine, 2015 A 46-year-old female patient was admitted to the intensive care unit (ICU) after liver transplantation. About an hour later after the ICU admission, she had no pupillary light reflex. Both pupils were also fixed at 5 mm.

A high-resolution binocular video-oculography system: assessment of pupillary light reflex and detection of an early incomplete blink and an upward eye movement [PDF]
, 2015 Background: The pupillary light reflex characterizes the direct and consensual response of the eye to the perceived brightness of a stimulus. It has been used as indicator of both neurological and optic nerve pathologies. As with other eye reflexes, this

Understanding the effects of mild traumatic brain injury on the pupillary light reflex
Concussion, 2017 The pupillary light reflex represents an optimal visual system to investigate and exploit in the mild traumatic brain injury (mTBI) population. Static and dynamic aspects of the pupillary light reflex were investigated objectively and quantitatively in ...
