Abstract
Purpose: To evaluate the efficiency (results) of the filtering surgery with stent Ex-PRESS implantation in the primary (POAG) and secondary (SOAG) open angle glaucoma patients.
Material and methods: The surgery results with the Ex-PRESS shunt implantation in 53 eyes of 44 patients at the age between 39-90 years old were analysed. In all patients were analysed the intraocular pressure (Ta), progression of glaucomatous changes in the visual field and optical coherence tomography (OCT) results.
Results: Among 33 Ex-PRESS shunts implanted in the POAG group were 10 in phakic and 23 pseudophakic eyes as well as in 20 eyes of patients with SOAG were 12 with pseudophakia. In both groups the target intraocular pressure after operation and during follow-up was observed. During follow-up the glaucomatous progression was observed in the visual fields results in 17 eyes (32.1%) and in the OCT in 4 eyes (7.4%). The postoperative complications: hypotony in 37 eyes (69,8%), hyphaema in 18 (36.96%) cases, uveal effusion in 1 (1.8%) case and stent dislocation in 3 (5.6%) were observed.
Conclusions: Operation procedure with the implantation of stent Ex-PRESS efficiently and long lasting decreases the intraocular pressure in the primary and secondary open angle glaucoma patients. The small invasiveness of this surgery procedure protects from any severe clinical complications. The use of Ex-PRESS shunt is an effective and safe method of the primary and secondary open angle glaucoma filtering surgery.
