RODRIGUEZ GUZMAN, D.; ZUNIGA LOPEZ, A.  and  SUASTE GOMEZ, E.. Respuestas pupilares a estímulos cromáticos en el espectro de 400 nm a 650 nm, en el estado estable. Rev. mex. fis. [online]. 2005, vol.51, n.4, pp.365-370. ISSN 0035-001X.

An instrumental methodology was implemented to analyze the pupillary responses in the dilation and contraction process elicited by chromatic stimulus. Chromatic stimuli were employed in the visible spectrum from 400 nm to 650 nm. Three different stimulation software was developed and used in order to obtain a contrasted pupillary response PG0, PG12 and PG20. This test was applied to 39 subjects (29 male, 9 female and 1 child, 22-52 years and 6 years), 10 of them were stimulated with PG0, 21 were stimulated with PG12 and 16 with PG20. 6 subjects participate at least in 2 tests. Ishihara plates were exhibited to the subjects before the stimulation, 37 of the present a normal vision color, 1 present deuteranopy.

Keywords : Pupillary response; chromatic stimulus; stable state; pupillary redilation; video-oculography.
