Videopupillometry
Videopupillometry is a non-invasive method used to measure the reflexes of the pupil in response to visual stimuli. The technique involves recording changes in pupil size and shape using a high-speed camera, typically at a rate of 30-60 frames per second. The recorded video is then analyzed to extract key parameters such as pupil diameter, area, and constrictory latency.
Videopupillometry is particularly useful in the assessment of autonomic nervous system function, particularly in the context
The technique relies on the principle that the pupil responds reflexively to changes in the intensity of
Videopupillometry presents several advantages over traditional pupilometry methods, which rely on static measurements of pupil size.
