Can pigment dispersion syndrome change eye color?
APR 21, 2018
PDS usually does not cause a noticeable change in eye color. The pigment released in this syndrome is from a tissue layer on the back of the iris, which is liberated when it rubs against the front surface of the lens. Happily, this tissue layer is not the source of one’s eye color. So, while in rare instances, so much pigment is released into the eye that the iris can take on a slightly brown tinge, this is really quite infrequent and should not be a concern.
