Abstract


Aim: To report the safety and efficacy of EX-PRESS glaucoma filtration device implantation in Chinese glaucoma patients.

Methods: Records of 38 eyes from 38 Chinese glaucoma patients who underwent EX-PRESS shunt implantation between August 2012 and June 2014 with at least 1 year of follow-up were retrospectively reviewed. Main outcome measures included intraocular pressure (IOP), visual acuity, success rate, number of topical antiglaucoma medications applied, and postoperative complications.

Results: The mean IOP reduced significantly from 25.8±12.4 mmHg before surgery to 15.1±6.3 mmHg at 1 year after surgery (p<0.005). Repeated measures ANOVA showed that IOP at all time points after surgery was significantly lower than IOP before surgery. 73.7% of patients achieved complete or qualified success.

Conclusions: EX-PRESS shunt implantation is safe and effective in Chinese patients.
