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 ]
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.
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.
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.
