Glaucoma due to ciliary body cysts and pseudoplateau iris: a systematic review of the literature

The diagnosis of angle-closure glaucoma secondary to iridociliary cysts is challenging and lacks compiled literature support. We present a rare case of bilateral angle-closure glaucoma associated with pseudoplateau iris due to multiple ciliary cysts and conducted a systematic review of the literature to find similar case reports published between November 2006 and November 2016. Only 19 case reports present treatment modalities, and most cases required more than one therapeutic approach for controlling the intraocular pressure. Pseudoplateau iris attributed to iridociliary cysts should be considered in the differential diagnosis of patients with narrow angles, particularly those with ocular hypertension and glaucoma, in which management is complex. In addition to gonioscopy, ultrasound biomicroscopy is considered the conclusive method for accurate diagnosis.
