A 68-year-old female was referred to the emergency ophthalmology clinic with a pigmented iris lesion and an intraocular pressure (IOP) of 38 in her left eye. Initial clinical assessment revealed the presence of a localized, flat, plaque-like peripheral and midperipheral iris lesion in one quadrant. Pigmented seeding on the rest of the iris surface and associated mild corectopia were observed. There were no notable episcleral sentinel vessels, and there was no iris neovascularization. On gonioscopy, heavy pigment invaded 8 clock hours of the angle (Fig. 1). The ciliary body was normal. Fundus examination, visual field testing, and optical coherence tomography all showed severe glaucomatous damage in the left eye (with normal testing in the right eye). The patient was initially managed medically using 4 topical glaucoma medications and systemic acetazolamide.
