Preliminary study on the treatment of acute angle closure glaucoma with high intensity focused ultrasound cycloplasty.

ABSTRACT: High-intensity focused ultrasound cycloplasty (UCP) can effectively reduce intraocular pressure in glaucoma patients. This work aimed to analyze the efficacy, safety, and mechanism of UCP in treating acute angle-closure glaucoma. We collected and retrospectively analyzed the preoperative and postoperative clinical data of 16 cases (16 eyes) with acute angle-closure glaucoma, including the number of sectors activated, intraocular pressure (IOP), central anterior chamber depth (ACD), lens zonule length (LZL), ciliary muscle thickness (CMT), and trabecular-ciliary process angle (TCA). Of the 16 eyes, one received a single UCP procedure with 8 sectors, and the others with 10 sectors. The mean IOP at follow-up time points after UCP was significantly lower than before UCP. The mean ACD at follow
