Pigment is the material that gives your iris its color. Pigment dispersion syndrome (PDS) happens when the pigment rubs off the back of your iris. This pigment then floats around to other parts of the eye. The tiny bits of pigment can clog your eye's drainage angle. This can cause eye pressure problems.
