The effect of pupil dilation on driving vision in Canada.
BACKGROUND To determine whether there is a clinically significant reduction in visual acuity (VA) or contrast sensitivity (CS), with and without glare, following examination with pupil dilation in patients currently driving. METHODS From November 1, 2004, to February 28, 2005, 105 consecutive patients were assessed in our institution. The better eye was assessed pre- and post-dilation with an...
متن کاملPupil Dilation and Eye-tracking
A video-based eye-tracker (e.g., the mobile Eyelink II or Eyelink Remote of SR research, Osgoode, Ontario, Canada) uses video cameras to record the eye position of human subjects, and hence, record pupil dilation and eye movements. The eyetracker puts a video cameras and infrared illuminators in front of the eye to record the position of the eye, cornea reflections, and the size of the pupil. U...
متن کاملNeuromodulatory Correlates of Pupil Dilation
Pupillometry has long been used as a measure of brain state. Changes in pupil diameter are thought to coincide with the activity of neuromodulators, including noradrenaline and acetylcholine, producing alterations in the brain state and corresponding changes in behavior. Here we review mechanisms underlying the control of pupil diameter and how these mechanisms are correlated with changes in co...

متن کاملMultisensory signalling enhances pupil dilation
Detecting and integrating information across the senses is an advantageous mechanism to efficiently respond to the environment. In this study, a simple auditory-visual detection task was employed to test whether pupil dilation, generally associated with successful target detection, could be used as a reliable measure for studying multisensory integration processing in humans. We recorded reacti...
