Quantitative assessments of pupillary light reflexes in neurocritically ill patients

The pupillary light reflex (PLR) is a component of bedside neurological examinations in intensive care units (neuroICUs). A quantitative pupillometer provides non-invasive and objective pupil reactivity parameter clinically significant for changes PLR neuroICUs. This article reviews the physiology importance parameters pupillometers. Moreover, this review discusses clinical applications pupillometers post-cardiac arrest prognostication monitoring elevated intracranial pressure worsening stroke, seizures, other diseases neuroICU. Quantitative pupillometry routine part an important tool
