Pupil reflex as a marker of activity and prognosis in heart failure: a longitudinal and prospective study

ESC Heart Failure
Aims Compensatory mechanisms in heart failure (HF) are triggered to maintain adequate cardiac output. Among them, hyperactivation of the sympathetic nervous system (SNS) is one of the main ones and carries a worse prognosis.

XR-Pupillometry: A novel approach to pupillometry for clinical care and beyond

The Pan-American Journal of Ophthalmology
Abstract Pupillometry is an emerging, noninvasive technique that measures pupil reactivity and provides deeper insights into ophthalmic and neurologic function. Extended reality (XR) technology has also emerged with powerful clinical capabilities in various medical specialties, particularly in neuro-ophthalmology functional testing.

Meaning and pupillometry

, 2017
The goal of the present dissertation is to examine the role of physiological arousal in meaning maintenance, using the Meaning Maintenance Model (MMM) as the guiding theoretical framework.The MMM is an integrative model in the existential psychology literature to explain both what meaning is and how people respond to lost meaning.
