BACKGROUND AND OBJECTIVES: To assess the effect of a novel surgical method for the treatment of chronic ocular hypotony (COH). The surgical method involves partially blocking the iridocorneal angle and decreasing aqueous humor outflow. A capsular tension ring (CTR) is placed in the iridocorneal angle. PATIENTS AND METHODS: Thirteen eyes of 13 patients were included in this retrospective, interventional case series. All of the eyes had severe ocular hypotony with a diagnosis of hypotony after vitreoretinal surgery or glaucoma filtration surgery. A CTR was placed in the iridocorneal angle via a corneal incision. The follow-up period was at least 1 year. Main outcome measurement was intraocular pressure (IOP). RESULTS: IOP increased in all of the eyes. The increase in IOP persisted during the follow-up period. Visual acuity increased or stabilized in all of the eyes. No ocular complications were noted due to the procedure. CONCLUSIONS: The authors have described a novel and simple technique for the setting of IOP in COH. Mechanical obstruction of aqueous humor outflow with a CTR can increase IOP and stabilize or improve vision in eyes with COH for a follow-up time longer than 12 months.
