BACKGROUND: To investigate changes of anterior segment morphology in primary angle-closure glaucoma after phacoemulsification using the Pentacam system. DESIGN: Prospective, interventional study, Zhongshan Hospital of Sun Yat-sen University. PARTICIPANTS: Eighty-five eyes from 60 patients with primary angle-closure glaucoma undergoing phacoemulsification. METHODS: Intraocular pressure was measured by Goldmann applanation tonometry. Anterior segment morphology was assessed using the Pentacam camera. MAIN OUTCOME MEASURES: The intraocular pressure, central anterior chamber depth, peripheral anterior chamber depth, anterior chamber volume, pupil diameter, and anterior chamber angle pre- and 3 months postoperative. RESULTS: A total 78 eyes of 55 patients with primary angle-closure glaucoma were included in the analysis. Thirty-two eyes (41.0%) had acute primary angle-closure glaucoma and 46 eyes (59.0%) had chronic primary angle-closure glaucoma. In both groups, statistically significant decreases in intraocular pressure and increases in anterior chamber volume, central anterior chamber depth, peripheral anterior chamber depth, and anterior chamber angle inferiorly, nasally, temporally, and, superiorly were observed at three months after phacoemulsification (all P < 0.001). CONCLUSIONS: Phacoemulsification induces significant changes in anterior segment morphology in primary angle-closure glaucoma accompanied by a significant fall in intraocular pressure in the short term. © 2012 The Authors.
