Characteristics of anterior uveal melanocytomas in 17 cases.

Objective: To evaluate a case series of anterior uveal melanocytomas (AUMs) for their distinct clinical, histopathologic, and high-frequency ultrasound (UBM) characteristics.

Design: Retrospective single-center case series.

Participants: Seventeen consecutive patients with AUMs.

Transpupillary Nd:YAG laser cystotomy for iris pigment epithelial cysts with secondary progressive angle closure.

Two patients were diagnosed as having unilateral iris pigment epithelial (IPE) cysts that were documented to enlarge and induce angle closure. Transpupillary IPE cystotomies were performed using the Nd:YAG laser as a prophylactic measure to prevent angle-closure glaucoma. Anterior chamber anatomy and cyst dimensions were assessed before, during, and after long-term follow-up using slit-lamp biomicroscopy, gonioscopy, and 20- or 35-MHz high-frequency ultrasound imaging.
