OBJECTIVE: To evaluate the efficacy and safety of Ex-PRESS implantation (Ex-PRESS) compared to trabeculectomy in the treatment of patients with open-angle glaucoma (OAG). METHODS: A comprehensive literature search using the Cochrane Methodology Register to identify randomized controlled clinical trials (RCCTs) comparing Ex-PRESS to trabeculectomy in patients with OAG. Efficacy estimates were measured by weighted mean difference (WMD) for the percentage intraocular pressure reduction (IOPR%) from baseline to end-point, and odds ratios (OR) for the complete success rate and postoperative interventions. Safety estimates were measured by OR for postoperative complications. Statistical analysis was performed using the RevMan 5.1 software. RESULTS: A total of four RCCTs were selected for this meta-analysis, including 215 eyes of 200 patients (110 eyes in the Ex-PRESS group, 105 eyes in the trabeculectomy group). There was no significant difference between Ex-PRESS and trabeculectomy in the IOPR% (WMD = 3.15; 95% confidence interval (CI), -6.17-12.47; P = 0.51). The pooled OR comparing Ex-PRESS to trabeculectomy for the complete success rate at one year after surgery were in favor of Ex-PRESS (OR = 2.93; 95% CI, 1.39-6.16; P = 0.005). The Ex-PRESS procedure was found to be associated with lower number of postoperative interventions (OR = 0.23; 95% CI, 0.07-0.81; P = 0.02) and with a significantly lower frequency of hyphema than trabeculectomy (OR = 0.21; 95% CI, 0.05-0.85; P = 0.03), whereas other complications did not differ statistically. CONCLUSION: In OAG, Ex-PRESS and trabeculectomy provided similar IOP control, but Ex-PRESS was more likely to achieve complete success, with fewer postoperative interventions. Complication rates were similar for the two types of surgery, except for a lower frequency of hyphema in the Ex-PRESS group. |
