Abstract Details


To investigate the effectiveness and safety of ExPRESS shunt surgery in different kind of our glaucoma patients.


Retrospective chart review. The study has been conducted at Pamukkale University, School of Medicine, Department of Ophthalmology


We performed ExPRESS glaucoma shunt (p 50) surgery on 62 eyes of 55 patients who have not been controlled with anti-glaucoma medications. All surgeries were done by single surgeon (AMA). Mean follow up time was 15,3 months (1,5-31 months). The pre-operative and post-operative intraocular pressures (IOP) were compared statistically. Complications (like hypotony) and anti-glaucoma medication usage were also noted. Surgical success was defined as IOP<18 mmHg without medication.


Forty eyes were diagnosed as having primary open angle glaucoma (POAG), 13 eyes had neovascular glaucoma, 3 eyes had secondary open angle glaucoma, 2 eyes had traumatic glaucoma 2 eyes had secondary angle closure glaucoma, and 2 eyes had juvenile glaucoma. Postoperatively, 6 eyes needed antiglaucoma medication for IOP control. Only two eyes developed post-operative hypotony with choroidal detachment, but both of them resolved spontaneously. Pre-operative mean IOP was 25,79 mm Hg and postoperative mean IOP was 15,79 mmHg (p< 0,001). The success rate of ExPRESS implant surgery for POAG patients (phacic and pseudophacic) was 100% in our study.


ExPRESS glaucoma shunt surgery is very effective and safe surgery with low complication rate. Main drawback of the surgery is its cost.
