Glaucomas: Pigment dispersion glaucoma and angle recession glaucoma

Abstract

Pigment dispersion syndrome (PDS) is a clinical entity characterized by the release of pigment granules throughout the anterior segment which has been attributed to friction between the posterior iris surface and the anterior zonular bundles [1]. Decreased outflow facility due to PDS may lead to increased intraocular pressure (IOP) and glaucomatous optic neuropathy (GON), which characterize pigment dispersion glaucoma (PDG). PDS is an autosomal dominant disorder with variable penetrance [2]. It is more common among young myopic males (between 30 and 40 years old) of white ethnicity with a positive family history of PDS. Usually both eyes are involved, although the disease may be asymmetric. The amount of pigment observed during slit lamp examination has not been correlated to the risk of converting to PDG [3]. © 2010 Springer-Verlag Berlin Heidelberg.
