Abstract

This chapter discusses pigment dispersion syndrome and pigmentary glaucoma. It is secondary form of open-angle glaucoma produced by the pigment dispersion in the anterior segment of the eye. Clinical signs and symptoms include iris change, corneal changes, anterior chamber changes, lens changes, angle changes, pigment deposition, and glaucoma. Iris transillumination appears to be most diagnostic clinical feature of pigmentary glaucoma. Pathogenesis of pigment dispersion syndrome and pigmentary glaucoma describes mechanism of pigment dispersion, and mechanisms of intraocular pressure rise. The differential diagnosis of pigmentary glaucoma includes any condition that produces pigmentation of the trabecular meshwork. Pseudoexfoliation syndrome is explained. Crystalline lens disorders are associated with several forms of glaucoma. Pseudoexfoliation syndrome (PXS) is one of the types where causes and effect association between lens abnormality and the glaucoma are present. Capsular delamination and exfoliation syndrome are explained. The characteristic exfoliation material becomes deposited on the anterior lens capsule. The constant rubbing action of pupil then scrapes the exfoliative material off the midzone of the lens giving rise to three distinct zones. These three zones are best demonstrated when the lens is examined with slit-lamp biomicroscopy after papillary dilation.
