Anterior segment imaging using optical coherence tomography and ultrasound biomicroscopy in secondary pigmentary glaucoma associated with in-the-bag intraocular lens.

A 43-year-old man with high myopia developed unilateral pigmentary glaucoma with recurrent episodes of painless blurred vision in the left eye following uneventful phacoemulsification. Bilateral cataract surgery was performed with capsular bag implantation of a +4.00 diopter AcrySof MA60 intraocular lens (IOL) (Alcon Laboratories) followed by a neodymium:YAG laser capsulotomy. Secondary iatrogenic dispersion syndrome in the left eye with subsequent intraocular pressure elevation was suspected in the presence of anterior chamber pigmented cells, circular epithelial iris loss around the pupil, and trabecular hyperpigmentation. Close contact between the edge of the IOL and the posterior pigmented iris epithelium, which was clinically suggested by anterior biomicroscopy, was documented by ultrasound biomicroscopy and optical coherence tomography of the anterior segment.
