Clinical observation of Ex-PRESS glaucoma drainage device for primary open angle glaucoma

Abstract

AIM:To observe the clinical effect of Ex-PRESS glaucoma drainage device with adjustable suture for primary open angle glaucoma.METHODS:The clinical data of 23 patients(including 29 eyes)from January 2013 to May 2015 who were diagnosed as primary open angle glaucoma were analyzed retrospectively. These patients who were 23～42 years old with the best corrected visual acuity(BCVA)from 50cm/finger count to 0.5 and the intraocular pressure(IOP)16～52mmHg did not respond well after using IOP-lowering drugs. After being treated with Ex-PRESS glaucoma drainage device associated with adjustable suture, the BCVA,IOP and the formation of filtering blebs were observed, while ultrasound biomicroscope(UBM )was used to observe whether the Ex-PRESS drainage device filterable passage was open or not.RESULTS:The mean BCVA was 0.06～0.5 postoperatively; the mean IOP was 10±3mmHg at 1wk after treatments, which decreased significantly compared to that before treatments(PCONCLUSION: Ex-PRESS glaucoma drainage device with adjustable suture for primary open-angle glaucoma is considered safe and effective. It is obvious that this clinical therapeutic technique is an ideal method with a low incidence of intraoperative risk and postoperative complications.
