Pigment dispersion syndrome and pigmentary glaucoma.
The pigment dispersion syndrome is a relatively uncommon condition, occurring as a result of pigment loss from the posterior-pigmented epithelium of the iris, with subsequent redeposition of the pigment throughout the anterior chamber. Obstruction of the trabecular meshwork occasionally leads to pigmentary glaucoma, with increased intraocular pressure, optic nerve head changes, and visual field loss. We present two cases of pigmentary dispersion syndrome, one of which progressed to pigmentary glaucoma with the eventual need for laser trabeculoplasty.
