Colvard pupillometer measurement of scotopic pupil diameter in emmetropes and myopes.
PURPOSE To prospectively compare the scotopic pupil size between emmetropes and myopes using a Colvard pupillometer. METHODS The pupil diameters of 55 normal subjects and 55 healthy myopic subjects were measured with the Colvard pupillometer in a low-light situation that simulated the level of light encountered while driving at night. RESULTS The mean (+/- SD) age of the emmetropic subjects...
متن کاملComparison of measurement of pupil sizes among the colvard pupillometer, procyon pupillometer, and NIDEK OPD-scan.
PURPOSE To compare pupil sizes measured with the Colvard pupillometer, Procyon pupillometer, and NIDEK OPD-Scan. METHODS Pupil diameter was measured in 90 consecutive eyes from 55 patients under mesopic and scotopic light conditions with all three instruments. RESULTS The mean scotopic pupil diameter was 6.3+/-0.98 mm with the Colvard pupillometer and 6.45+/-1.01 mm with the Procyon pupillo...
متن کاملConvenient evaluation of mental stress with pupil diameter.
This study proposes a convenient method of evaluating mental stress. The potential of monitoring changes in pupil diameter as a measure of human reliability while operating human-machine systems was examined experimentally. An experiment was carried out to clarify the relation between changes in pupil diameter and autonomic nervous activity by measuring an electrocardiogram and pupil diameter w...
متن کاملPupil examination: validity and clinical utility of an automated pupillometer.
Pupillary size and reactivity have long been a critical component of the clinical assessment of patients with neurological disorders. The pupillary examination may provide critical information related to new or worsening intracranial pathology and facilitate prompt intervention to minimize further neuronal damage. With this in mind, intensive care nurses caring for neurologically impaired patie...
