Pigment dispersion syndrome in pseudophakic corneal transplants

We observed the pigment dispersion syndrome in two patients after keratoplasty with posterior chamber intraocular lenses. In addition to a heavily pigmented trabecular mesh-work and iris transilluminating defects, an inferior linear pigmented endothelial line was seen in both patients. One patient developed glaucoma, which was well controlled with medication. Pigment dispersion syndrome in patients with penetrating keratoplasty should not be confused with an allograft reaction but should alert the transplant surgeon that a different process is occurring.
