Angle closure caused by multiple, bilateral iridociliary cysts

A case of high, broad, peripheral anterior synechiae caused by multiple, bilateral iridociliary cysts is reported. The peripheral anterior synechia in our case extended to the corneal endothelium beyond Schwalbe's line, and iris atrophy in the region of the cysts was found. Ultrasound biomicroscopic imaging showed that multiple, bilateral iridociliary cysts causes elevation of the iris structure.
