The relationship of sleepiness and dynamic pupillometry: A 24-hour evaluation

Abstract

This article evaluates the relationship between sleepiness and pupillometry in patients tested for 24 hours. The volunteer was tested every 30 minutes. The parameters for the pupillary reflex were extracted using image processing algorithms and the graphs related to latency, and constriction of the pupil were presented. Considering the results, it is suggested that is not possible to infer a direct relationship between the dynamic pupillometry and sleepiness. © 2013 Springer-Verlag.
