Posterior Capsular Pigment Deposition: A Rare Presentation of Pigment Dispersion Syndrome

Abstract

Pigment dispersion syndrome (PDS) is characterized by the dispersion of pigment from the iris pigment epithelium and its deposition on the anterior segment structures like endothelium, iris surface and trabeculum. 1,2 The typical findings include Kruken-berg spindle, iris transillumination, heavy trabecular meshwork pigmentation, and a concave iris on gonioscopy. 3,4 The underlying pathophysiology is thought to be related to mechanical rubbing between the posterior surface of the concave iris and the ante-
