AbstractPURPOSE: To document anatomic effects of phacoemulsification versus combined phaco-trabeculectomy on drainage angle in primary angle closure glaucoma (PACG). METHODS: Indentation gonioscopy and ultrasound biomicroscopy were performed preoperatively, and then at 1 year after phacoemulsification alone or combined phaco-trabeculectomy in PACG patients. RESULTS: Seventy-two PACG eyes of 72 patients were included in this study. Thirty-eight eyes were randomized into receiving phacoemulsification alone, whereas 34 eyes had combined phaco-trabeculectomy. The mean extent of synechial angle closure was significantly reduced from 266.4° to 198.9° (P<0.001) by phacoemulsification alone, and from 266.0° to 227.2° (P=0.03) by combined surgery. The mean angle opening distance (AOD 500) measured by ultrasound biomicroscopy was significantly increased from 208.0 to 468.0 μm (P<0.001) by phacoemulsification, and from 214.6 to 344.4 μm (P<0.001) by combined surgery. The mean trabecular-ciliary process distance was significantly increased from 824.6 to 1043.6 μm (P<0.001) by phacoemulsification, and from 800.9 to 951.5 μm (P=0.01) by combined surgery. The mean anterior chamber depth was significantly increased from 1798.6 to 3528.4 μm (P<0.001) by phacoemulsification alone, and from 1781.6 to 3297.8 μm (P<0.001) by combined surgery. Phacoemulsification alone resulted in significantly greater postoperative angle opening distance 500 (P<0.001) and anterior chamber depth (P<0.001) than phaco-trabeculectomy. CONCLUSIONS: Phacoemulsification alone resulted in greater opening of drainage angle and greater deepening of anterior chamber than combined phaco-trabeculectomy in PACG eyes. SYNOPSIS: Phacoemulsification alone resulted in greater opening of drainage angle and greater deepening of anterior chamber than combined phaco-trabeculectomy in PACG eyes. © 2010 Lippincott Williams & Wilkins, Inc.
