Pigmentary glaucoma is caused by pigment dispersion, a disorder characterized by pigment liberation from the iris epithelium. Onset is at a somewhat early age, developing in 20 to 40 year old patients. A distinguishing feature of pigmentary glaucoma is that the iris tends to have a concave (bowed back toward the lens) configuration.
