Combined Phacoemulsification and Ex-PRESS Implant with Everting Suture in Primary Angle-Closure Glaucoma: Survival Analysis and Predictive Factors.

ABSTRACT: The purpose of this study was to evaluate the efficacy and safety of combined phacoemulsification and Ex-PRESS implant with everting suture in primary angle-closure glaucoma (PACG) and to examine predictive factors of failure. Twenty-three eyes of 18 patients were enrolled. Data about time of removal of releasable sutures and traction of the everting suture and about changes in intraocular pressure (IOP) were collected, as well as comprehensive ophthalmic examinations. Success was defined by the following criteria: IOP ? 18 mmHg (criterion 1); IOP ? 15 mmHg (criterion 2); and IOP ? 12 mmHg (criterion 3). Success was categorized as complete or qualified, depending on whether it was reached without or with drugs, respectively. Success rate was assessed with Kaplan-Meier survival analysis with a Cox proportional hazard model to adjust for potential confounders. The lowering of IOP and the reduction of medications were statistically significant at every follow-up visit compared with the baseline (p < 0.05). The complete success rates were 87%, 70%, and 17% accordingly to criterion 1, 2, and 3; the qualified success rates were 93%, 70%, and 20%, respectively. Most of the complications resolved spontaneously and conservatively. In conclusion, combined phacoemulsification and Ex-PRESS Minishunt implant with everting suture is a safe and effective surgery, even in PACG, lowering IOP and number of medications.

Project description:BackgroundTo compare the efficacy of Ex-PRESS implantation versus trabeculectomy combined with phacoemulsification.MethodsA retrospective 12-month study on patients with coincident primary open-angle glaucoma (POAG) and cataract. The patients underwent combined phacoemulsification and Ex-PRESS implant (Phaco-ExPRESS, n = 35) or phacotrabeculectomy (Phaco-Trab, n = 35). The morphological structures of the filtering bleb were examined by slit-lamp, anterior segment optical coherence tomography (AS-OCT) and in vivo confocal microscopy (IVCM). Complete success was defined as postoperative intraocular pressure (IOP) < 18 mmHg without the use of anti-glaucoma medication. Qualified success was defined as postoperative IOP < 18 mmHg with or without anti-glaucoma medications. The data were collected preoperatively and postoperatively at 2 weeks, 1 month, 3 months, 6 months, and 12 months.ResultsNo significant difference in the variables such as age, IOP and perimetry was found between the groups of Phaco-ExPRESS and Phaco-Trab. At the one-year postoperative visit for filtering blebs, Phaco-ExPRESS increased the mean area of epithelial microcysts significantly from 0.10 ± 0.05 to 0.20 ± 0.09 μm2 per μm2, while Phaco-Trab decreased the mean area significantly from 0.08 ± 0.04 to 0.04 ± 0.06 μm2 per μm2. Notably, the hyperreflective dots detected by IVCM decreased by 84.9% in Phaco-ExPRESS but increased by 36.3% in Phaco-Trab. The hyperreflective dots were further identified as neutrophil- and monocyte-like cells. The number of these cells were negatively correlated with the microcysts area (r = - 0.7, P < 0.01) but positively associated with the grade of connective tissue (r = 0.5, P < 0.01). By creating different microstructural changes in the filtering blebs, Phaco-ExPRESS produced a higher complete success rate (84.9% vs. 41.2%, P < 0.01) and significant decrease in the number of anti-glaucoma medications (P < 0.01) when compared with those in Phaco-Trab. However, the qualified success showed no significant difference between the two groups (100.0% vs. 91.2%, P = 0.24).ConclusionsAt the one-year follow-up, Phaco-ExPRESS generated better filtering bleb with larger area of microcysts, looser connective tissues, and less inflammation than that of Phaco-Trab, providing adequate IOP control and less IOP-lowering medications. These findings indicate that Phaco-ExPRESS could be more preferred than Phaco-Trab for the treatment of patients with coincident POAG and cataract.
