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 fhoto-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 [1], which constitute the third cause of death in Venezuela during the last five years [2]. However, in Venezuela, specialists do not have a system for quantifying the clinical parameters, neither carry out the graphic representations of these important parameters.
