What Is It? Pigment Dispersion Syndrome is an uncommon condition. Most commonly effected are nearsighted males between the ages of 30 and 50. It is also more common in Europeans. The cause of pigment dispersion is a mechanical rubbing between two ocular structures: the IRIS and ZONULES. The iris is the colored part of the eye. It constricts and dilates to change the size of the pupil (depending upon the surrounding light). Behind the iris is the lens. The lens helps focus our vision.
