Studies published in peer-reviewed journals continue to demonstrate the effectiveness of NeurOptics' NPi in helping clinicians improve patient outcomes. The NPi and automated pupillometry such as NeuroLight (QPi) have also recently been included in the updated 2020 American Heart Association (AHA) Guidelines for Cardiopulmonary Resuscitation (CPR) and Emergency Cardiovascular Care (ECC) as an objective measurement supporting brain injury prognosis in patients following cardiac arrest. On the other hand, NeuroLight features a touchscreen display and utilizes a reusable opaque eyecup that isolates from ambient light. This consumable allows ambient light to pass through, which can lead to data reproducibility issues. The main distinction lies in the NPi’s use of a transparent eyecup that contains an electronic component for patient identification and results recording, making it unique to each patient. The NeuroLight and NPi pupillometer are both device for measuring pupils but differ significantly in terms of ergonomics and functionality. Neurological assessment with NeuroLight pupillometer (IDMED, IDMED Corp.) NPi-300 automated infrared pupillometer (NeurOptics, Inc.)Īnother automated pupillometer named NeurOptics' Neurological Pupil index (NPi) can offer a consolidated parametric approach to mitigate subjectivity. Abnormalities in pupillary responses can be indicative of underlying neurological disorders, such as traumatic brain injury, stroke, cardiac arrest or certain neurodegenerative diseases. They are essential in the clinical monitoring and neurological assessment of the patient. The pupil size and reactivity are daily measurements and part of the protocol for critically injured or ill patients. Pupil data can be uploaded to the patient record, eliminating the possibility of data entry errors. Īutomated pupillometry removes subjectivity from the pupillary evaluation, providing a more accurate trend of pupil data, and allowing earlier detection of changes for more timely patient treatment. It displays through a qualitative scale a quantitative interval for each color associated with its number. Moreover, the index of Neurolight pupillometer is color-coded for a quick clinical interpretation. Its quantitative nature provides objective and more reliable assessment. It provides objective data and can detect subtle changes that might not be apparent to the naked eye. With an automated pupillometer and an algorithm analyzing the pupil continuously for 5 seconds, the Quantitative Pupillometry Index (QPi) can measure pupillary reactivity and provides a numerical value. It involves the automatic constriction and dilation of the pupils in response to changes in light intensity or accommodation. The pupillary light reflex is the constriction of the pupils when exposed to bright light, protecting the retina from excessive light exposure. An automated pupillometer also provides a reliable and effective way to quantitatively classify and trend the pupil light response. Independent of examiner, an automated pupillometer offers reproducible and precise measurements by eliminating variability and subjectivity, expressing pupil reactivity numerically so that both pupil size and reactivity can be trended for changes, just like other vital signs. qPLR corresponds to the percentage of pupillary constriction to a calibrated light stimulus. sPLR is opposed to quantitative PLR (qPLR) that is provided by an automated pupillometer. PLR is historically assessed by a nurse or a clinician using a manual flash lamp (sPLR, “s” stands for standard). Automated Pupillometry Īn automated pupillometer is a portable, handheld device that provides a reliable and objective measurement of pupillary size, symmetry, and reactivity through measurement of the pupillary light reflex (PLR). The most common type is the Haab scale, or Haab's pupillometer, which is a series of graduated filled circles on a slide ruler. There are several types of manual pupillometers. Manual pupillometry Ī manual pupillometer measures pupil size via a comparison chart method. Some instruments for measuring pupillary distance (PD) are often, but incorrectly, referred to as pupilometers. In addition to measuring pupil size, current automated pupillometers may also be able to characterize pupillary light reflex. Pupillometer, also spelled pupilometer, is a medical device intended to measure by reflected light the size of the pupil of the eye.
