Pigmentary dispersion.
A long-term study of primary pigmentary dispersion has shown that the condition is commoner in males than females and appears most frequently in the third decade. After 10 years there may be a significant reduction in the amount of pigment deposited on the cornea, and the condition of several patients receiving treatment for glaucoma has remained under control when treatment has been stopped.
متن کاملPigment 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...
متن کاملUltrasound biomicroscopy in asymmetric pigment dispersion syndrome and pigmentary glaucoma.
OBJECTIVE To identify differences in anterior chamber anatomy among patients with asymmetric pigment dispersion syndrome and no other discernible cause for the asymmetry. METHODS Ultrasound biomicroscopy and A-scan biometry were performed on both eyes of 13 patients with asymmetric pigment dispersion syndrome without a known cause for asymmetric involvement. A radial perpendicular image in th...
متن کاملSecondary pigmentary glaucoma in patients with underlying primary pigment dispersion syndrome
Primary pigment dispersion syndrome (PPDS) is a bilateral condition that occurs in anatomically predisposed individuals. PPDS may evolve into pigmentary glaucoma, but it is difficult to predict which patients will progress. Secondary pigment dispersion is more often unilateral and acquired as a result of surgery, trauma, or intraocular tumor, but can likewise lead to pigmentary glaucoma. We rep...
متن کاملCommon sequence variants in the LOXL1 gene in pigment dispersion syndrome and pigmentary glaucoma
BACKGROUND Single nucleotide polymorphisms (SNPs) within the LOXL1 gene are associated with pseudoesfoliation syndrome and pseudoesfoliation glaucoma. The aim of our study is to investigate a potential involvement of LOXL1 gene in the pathogenesis of pigment dispersion syndrome (PDS) and pigmentary glaucoma (PG). METHODS A cohort of Caucasian origin of 84 unrelated and clinically well-charact...
