Inter-device reliability of the NPi-200 and NPi-300 pupillometers

Impact of acute intoxication on quantitative pupillometry assessment in the emergency department

“…Therefore, QP may fill an unmet need, if future work confirms its utility as an early diagnostic tool for other pathologies unrelated to alcohol or other substance use. Quantitative measures may also provide added value in terms of data standardization and reduce variability in interpretation across medical teams and shift changes during longitudinal care of patients with brain injuries, as shown in prior work 11–15 …”

“…The device is positioned at a consistent distance from the subject, after which a beam of light is administered over a 3‐second interval during which images of the pupil are captured at a rate of more than 30 frames per second and subsequently analyzed. The device has been well evaluated for the replicability, precision, and accuracy of its measurements in various settings 11–15 …”
