Application of Pupillometry in Neurocritical Patients

Journal of Personalized Medicine, 2023
Pupillary light reflex (PLR) assessment is a crucial examination for evaluating brainstem function, particularly in patients with acute brain injury and neurosurgical conditions. The PLR is controlled by neural pathways modulated by both the sympathetic and parasympathetic nervous systems.

Best Practices and Advice for Using Pupillometry to Measure Listening Effort: An Introduction for Those Who Want to Get Started

Trends in Hearing, 2018
Within the field of hearing science, pupillometry is a widely used method for quantifying listening effort. Its use in research is growing exponentially, and many labs are (considering) applying pupillometry for the first time.

Cortical synchrony is reduced in Alzheimer's disease and relates to arousal state. [PDF]

Alzheimers Dement
Abstract INTRODUCTION The brain is a complex dynamical system, influenced by arousal state. Cortical synchrony supports information processing and is disrupted in Alzheimer's disease (AD). Locus coeruleus (LC) integrity and pupillometry index arousal system structure and function.

Evaluation of static and dynamic pupil responses in patients with acromegaly with automatic pupillometer [PDF]

BMC Ophthalmology
Background Acromegaly is a chronic disorder caused by excessive secretion of growth hormone and IGF-I, usually from a benign pituitary adenoma, leading to systemic complications and increased mortality.

Effects of Digital Noise Reduction Processing on Subjective and Objective (Pupillometry) Assays of Listening Effort [PDF]

Audiology Research
Background/Objectives: Although research has demonstrated the positive impacts of hearing aid (HA) digital noise reduction (DNR), limited research is available on the impacts of the strength of DNR on listening effort. This study evaluated the effects of

Superior reproducibility and repeatability in automated quantitative pupillometry compared to standard manual assessment, and quantitative pupillary response parameters present high reliability in critically ill cardiac patients.

PLoS ONE, 2022
BackgroundQuantitative pupillometry is part of multimodal neuroprognostication of comatose patients after out-of-hospital cardiac arrest (OHCA). However, the reproducibility, repeatability, and reliability of quantitative pupillometry in this setting ...
