    Abstract:
    PURPOSE: To investigate and compare the effects of phacoemulsification as an initial procedure to control intraocular pressure (IOP) in eyes with acute primary angle closure (APAC) and chronic primary angle-closure glaucoma (CPACG) with coexisting cataracts and peripheral anterior synechiae (PAS) of greater than 180 degrees. SETTING: Prospective, cross-sectional study. METHODS: Thirteen patients (13 eyes) with APAC and 10 patients (10 eyes) with CPACG were enrolled in the study. IOP control in the 2 groups was compared at final follow-up. Other outcome measures included visual acuity, anterior chamber depth, gonioscopic appearance, and complications. RESULTS: The postoperative IOP was reduced in both the APAC and CPACG groups. As assessed at last follow-up (median 6 mo), IOP in the APAC group was significantly lower than that in the CPACG group. The absolute success rate was 100% in the APAC group and 80% in the CPACG group. The number of hypotensive medications decreased in both APAC and CPACG group. The postoperative degree of PAS was relieved in 11 of 12 eyes with APAC and 5 of 9 eyes with CPACG. CONCLUSIONS: Initial phacoemulsification performed to provide short-term control of IOP is more efficacious in patients with APAC than in those with CPACG, especially when PAS is greater than 180 degrees.
