Pupilometer

Pupilometer, also spelled pupillometer, is a name for two different devices—one used in critical care medicine, which measures reactivity through measurement of the pupil light reflex, and the other used in ophthalmology, which measures the distance between pupils through visual stimuli. Pupilometer, also spelled pupillometer, is a name for two different devices—one used in critical care medicine, which measures reactivity through measurement of the pupil light reflex, and the other used in ophthalmology, which measures the distance between pupils through visual stimuli. An automated pupillometer is a portable, handheld infrared device that provides a reliable and objective measurement of pupillary size, symmetry, and reactivity through measurement of the pupil light reflex. Independent of examiner, an automated pupillometer eliminates variability and subjectivity, expressing pupil reactivity numerically so that both pupil size and reactivity can be trended for changes, just like other vital signs. An automated pupillometer also provides a reliable and effective way to quantitatively classify and trend the pupil light response. Automated pupillometry removes subjectivity from the pupillary evaluation, providing more accurate trend of pupil data, and allowing earlier detection of changes for more timely patient treatment. Pupil data can be automatically uploaded to the patient record, eliminating the possibility of data entry error.
