• To provide an overview of the accuracy of these new instruments.
• To explore the potential applications of pupillary assessment in critical care.

Main Methods:

• Review of the development of infrared pupillometry technology.
• Analysis of studies documenting inter-observer agreement for pupillary measurements.
• Comparison of infrared pupillometry with standard pen-light examinations.

Main Results:

• Portable infrared pupillometry instruments have recently become available for clinical settings.
• Studies indicate acceptable accuracy and inter-observer agreement for these devices.
• The pupil's function offers valuable insights into patient status.

Conclusions:

• Portable infrared pupillometry devices are a validated tool for clinical use.
• These devices can aid in the assessment and management of critically ill patients.
• Pupillary reflex monitoring holds significant promise for enhancing patient care in critical illness.
