Pupillometry in perioperative medicine: a narrative review.
TL;DR: Pupillometry is a technique for objective quantification of nociception that takes into account the central processing of noxious stimuli and its sympathetic response as discussed by the authors, which has the potential to personalize pain management in perioperative and intensive care unit environments.
