Measurement of Direct and Consensual Light Reflex (original) (raw)

2015

Abstract

The main contribution of this research is to develop of a new measuring device for measuring direct and consensual light reflex of human pupil, hence to give opportunity to map physical and mental states of the patients. In this case the pupillary light reflex means changing of diameter of pupil due to constant light stimulus as a function of time. Determination of the diameter happens by means of image processing. Several diagnostic research consider pupillary light reflex. That is not unintention al, since for light reflex the autonomous nervous system is responsible and this provides objectivity, furthermore affects many parts of the nervous system – such as the retina, the nerves and some parts of the central nervous system – that makes suitable to find difference between several physical and mental states. During the development process of the device being cost -effective was one of the most important aspects, so if at a point a self -developed part would have been more expensi...
