  2. Pupillometry - Wikipedia

    en.wikipedia.org/wiki/Pupillometry

    Pupillometry, the measurement of pupil size and reactivity, is a key part of the clinical neurological exam for patients with a wide variety of neurological injuries. It is also used in psychology . [ 1 ] [ 2 ]

  3. Pupilometer - Wikipedia

    en.wikipedia.org/wiki/Pupilometer

    Automated pupillometry removes subjectivity from the pupillary evaluation[5], providing a more accurate trend of pupil data, and allowing earlier detection of changes for more timely patient treatment. Pupil data can be uploaded to the patient record, eliminating the possibility of data entry errors.

  4. Neurological pupil index - Wikipedia

    en.wikipedia.org/wiki/Neurological_Pupil_Index

    The Neurological Pupil index, or NPi, is an algorithm developed by NeurOptics, Inc., that removes subjectivity from the pupillary evaluation. A patient's pupil measurement (including variables such as size, latency, constriction velocity, dilation velocity, etc.) is obtained using a pupillometer, and the measurement is compared against a normative model of pupil reaction to light and ...

    Eckhard Heinrich Hess (27 September 1916 – 21 February 1986) [1] was a German-born American psychologist and ethologist, known for his research on pupillometry and animal imprinting. He joined the Department of Psychology at the University of Chicago as an instructor in 1948. He became a full professor in the Department of Psychology in 1959 ...

    Eye tracking device Scientists track eye movements in glaucoma patients to check vision impairment while driving.. Eye tracking is the process of measuring either the point of gaze (where one is looking) or the motion of an eye relative to the head.

  7. Pupillary response - Wikipedia

    en.wikipedia.org/wiki/Pupillary_response

    Dilation and constriction of the pupil. Pupillary response is a physiological response that varies the size of the pupil between 1.5 mm and 8 mm, [1] via the optic and oculomotor cranial nerve.

  8. Steady state visually evoked potential - Wikipedia

    en.wikipedia.org/wiki/Steady_state_visually...

    In neurology and neuroscience research, steady state visually evoked potentials (SSVEPs) are signals that are natural responses to visual stimulation at specific frequencies.

  9. Pupil - Wikipedia

    en.wikipedia.org/wiki/Pupil

    The pupil is a hole located in the center of the iris of the eye that allows light to strike the retina. [1] It appears black because light rays entering the pupil are either absorbed by the tissues inside the eye directly, or absorbed after diffuse reflections within the eye that mostly miss exiting the narrow pupil.
