Design and Implementation of an Acquisition System for the Photo-motor Response of the Iris

This paper presents a new development of an automated system for: stimulation, acquisition and the pupilar image processing (it includes segmentation and visualization in real time), issued from the photo-motor and consensual response of the iris. The physician can observe in the system interface: a graphic representation of the variation and change of speed of diameter and pupilar area as a function of time, from both pupils. In addition the magnitudes of clinical parameters, such as: the largest and smaller pupilar diameter, the maximum and minimum pupilar area, the eccentricity of each pupil, jointly with the inter pupilar distance. These data have a great interest for diagnosis and evaluation of lesions or illnesses of the central nervous system, which constitute the third cause of death in Venezuela during the last five years. However, in Venezuela, specialists do not have a system for quantifying the clinical parameters, neither carry out the graphic representations of these important parameters.
