The Effect Of Ex-PRESS Filtration Device In Primary Open Angle Glaucoma

AIM:To observe the effect of Ex-PRESS glaucoma filtration device in primary open angle glaucoma.METHODS:Totally41patients54eyes with primary open angle glaucoma were divided into two groups. The study group consists of19patients (25eyes) who underwent Ex-PRESS glaucoma filtration device implantation. The control group consists of22cases (29eyes) who underwent trabeculectomy. Two groups were compared with the average operation time,post-operative visual acuity, anterior chamber, intraocular pressure, filtering bleb and other complications.RESUILS:In Study group operation time was (34.60±4.43) minutes,1day postoperative shallow anterior chamber in1eye and hyphema in1eye,1week postoperative high intraocular pressure in2eyes,3months postoperative decreased vision in1eye, functional filtering blebs in24eyes, intraocular pressure was (11.5±5.8) mmHg. The control group operation time was (44.37±3) minutes,1day postoperative shallow anterior chamber in13eyes, anterior chamber bleeding or exudation in12eyes,1week postoperative high intraocular pressure in8eyes,3months postoperative decreased vision in6eyes, functional filtering blebs in25eyes, intraocular pressure was (13.6±6.7) mmHg. The study group can shorten the operation time and reduce early postoperative shallow anterior chamber, lower intraocular pressure and incidence of anterior chamber exudation and bleeding. The study group can control postoperative IOP to a lower degree. Comparing with the traditional operation, the study group had equivalent effect in postoperative visual effects and functional filtering bleb.CONCLUSION:Ex-PRESS glaucoma filtration device implantation in primary open angle glaucoma can shorten operation time, reduce the postoperative complications, and has the characteristics of high safety and good efficacy.
