The outcome analyses performed automatically using Revman 5.3 included intraocular pressure reduction （IOPR）, postoperative success rate, anti-glaucoma medications reduction and the incidence of adverse events.RESULTS： We included four qualified studies incorporating a total of 215 eyes for quantitative synthesis. The weighted mean difference （WMD） of IOPR between canaloplasty and trabeculectomy from baseline to 12mo was -2.33 （95%CI： -4.00, -0.66）. There was not significant improvement in the complete or qualified success rate （OR： 0.58, 95%CI： 0.26, 1.31; OR： 0.50, 95%CI： 0.10, 2.44, respectively）. Similarly, no statistically significance was observed in anti-glaucoma mediations reduction （WMD： -0.54, 95%CI： -1.18, 0.09）. Sensitivity analysis of the primary outcome estimate confirmed the stability of the Meta-analysis result.CONCLUSION： Trabeculectomy seems to be more effective in lowering IOP up to 12mo when comparing with canaloplasty. Canaloplasty does not seem to be inferior to trabeculectomy considering the postoperative success rate or the number of postoperative anti-glaucoma medications. Meanwhile, it has an advantage of less bleb related complications.展开更多
