Recurrent iris cyst discharge.

A 23-year-old woman with the diagnosis of anterior uveitis in the left eye was referred to our clinic. Circumferential midzonal iris epithelial cysts were observed in the right eye and corneal endothelial pigment precipitates and diffuse pigment discharge in the anterior chamber of the left eye. Topical prednisolone acetate was prescribed. After 2 days, hyperemia and pain decreased in the left eye and started in the right eye. During the following 3 months, the patient experienced 3 similar episodes, which resulted in diffuse pigment deposition in the anterior chamber angles. Intraocular pressure (IOP) elevation was observed after 1 week and 3 weeks in the left eye and right eye, respectively. Topical antiglaucomatous medication was prescribed. Nine months after the last episode, the uncorrected distance visual acuity was 20/20 and the IOP was 15 mm Hg bilaterally. The iris showed diffuse transillumination, and the pupils were unresponsive to light.
