Pigmentary dispersion.

چکیده
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.

Secondary 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 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...

OBJECTIVE To test the hypothesis that the retinal pigment epithelial/photoreceptor complex is affected in patients with pigment dispersion syndrome and/or in patients with pigmentary glaucoma. METHODS Electro-oculograms were recorded from patients with pigment dispersion syndrome, pigmentary glaucoma, ocular hypertension, and primary open-angle glaucoma and from control subjects.

This study involved a group of 407 patients (799 eyes) with pigment dispersion syndrome gathered from a glaucoma population of 9200 patients. The sex distribution was equal. The majority (65 Y.) of patients were myopic. The incidence of retinal detachment was 6-4 %. No patients were black, but 5 were mulatto. Approximately one-quarter of the patients with pigment dispersion syndrome (31 % of th...
