The aim of this article is to describe the methodology used to determine pupillary dynamic evoked by isoluminant chromatic stimuli using Infrared (IfR) High Speed Video-oculography (HSV) in order to know the effect of color on the dynamic. It was done in seven healthy selected subjects. Stimuli were characterized by reflectance spectrum. HSV record was taken in darkness with an infrared light system (IRS) through consensual pupillary reflex. With this HSV is possible to identify differences in the chromatic pupillary dynamic relating it to Latency Time . Results indicate that pupillary latency time is affected by the chromatic stimulus employed.
