Pigmentary dispersion glaucoma secondary to posterior chamber intra-ocular lenses

Thirteen cases of pigmentary dispersion glaucoma are presented. These had in common heavy pigment granule deposition in the trabecular meshwork in the operated eye alone, a history of posterior chamber intra-ocular lens implantation, and mild to marked iris pigment atrophy in areas contingent with or adjacent to the lens. High intra-ocular pressures were usually transient and easily controlled. One, however, eventually required trabeculoplasty.
