Kocaeli Üniversitesi Tıp Fakültesi Göz Hastalıkları Ana Bilim Dalı, Kocaeli, Prof. Dr.
Pigment dispersion syndrome (PDS) is characterized by a loss of pigment from the mid-peripheral iris, which is deposited throughout the anterior segment of the eye. A triad of signs characterizes the condition: midperipheral iris pigment epithelial defects, deposition of pigment on the zonules, anterior and posterior lens surfaces, iris, cornea endotelium, and the trabecular meshwork. It is more commonly observed in the younger age group and myopi. Ultrasound biomicroscopy and anterior segment optical coherence tomography have demonstrated that the posterior bowing of the iris in eyes with PDS .The risk of a patient with PDS developing glaucoma is 10% to 50%. Over the years, this condition can regress.PDS with a laser iridotomy or miotic therapy can correct the concave iris configuration and decrease pigment shedding, which can reduce the risk of the development pigmentary glaucoma. If medical treatment fail to lower intraocular pressure, fitration surgery becomes necessary. Keywords : Pigment dispension syndrome, glaucoma, laser
