	abstract = {PR{\'e}CIS:: This retrospective study found that combined phacoemulsification and endocyclophotocoagulation reduced intraocular pressure (IOP) to a greater degree in angle-closure glaucoma versus open-angle glaucoma and was effective for all stages of glaucoma. PURPOSE: Endocyclophotocoagulation (ECP) laser treatment of the ciliary processes is believed to decrease IOP by reducing aqueous production. Anecdotal experience in angle-closure glaucoma suggests that it may also lower IOP by opening the drainage angle to promote aqueous outflow. This study sought to evaluate combined phacoemulsification and ECP (phaco/ECP) in eyes with different types and stages of glaucoma. PATIENTS AND METHODS: A Retrospective chart review of eyes that underwent phaco/ECP between October 2010 and December 2016 at one institution was conducted. RESULTS: In 63 eyes of 63 patients with an average of 3.0{\textpm}1.7 years of follow-up, the 22 eyes with chronic angle-closure glaucoma (CACG) had greater IOP reduction and medication reduction than the 41 eyes with primary open-angle glaucoma at both 1 year (6.4 vs. 2.1 mm Hg, P=0.01; 0.9 vs. 0.2 medications, P=0.04) and final follow-up (6.2 vs. 2.4 mm Hg, P=0.02; 0.9 vs. 0.3 medications, P=0.05). There was no difference in IOP reduction or medication reduction for eyes with mild, moderate, or advanced glaucoma at both 1 year (3.5, 3.9, 0.5 mm Hg, respectively, P=0.18; 0.3, 0.6, 0.4 medications, P=0.58) and final follow-up (3.3, 4.8, 0.7 mm Hg, P=0.11; 0.1, 0.8, 0.4 medications, P=0.14). CONCLUSIONS: Eyes with CACG were more responsive to phaco/ECP in terms of IOP and medication reduction compared with eyes with primary open-angle glaucoma. This finding could be partially or entirely due to concurrent cataract extraction and greater CACG preoperative IOP. Phaco/ECP was effective in all stages of glaucoma.},
