Evaluation of Ex-PRESS® Mini Glaucoma Shunt (P 200) Implantation Outcomes In Pseudophakic Eyes

Özet

Purpose: To evaluate the outcomes of Ex-PRESS (P 200) mini-glaucoma shunt implantation surgery in pseudophakic eyes with medically uncontrollable open-angle glaucoma (OAG) for effi cacy and safety. Materials and Methods: Twenty-one eyes of 21 patients who had primary open-angle or pseudoexfoliation glaucoma were undergone Ex-PRESS shunt implantation surgery. Patients with a minimum of 12 months follow-up were included in the study, and fi les were reviewed retrospectively. Preoperative (pre-op) demographic characteristics, intraocular pressure (IOP), visual acuity (VA), the number of medications used were assessed. Postoperative (post-op) 1st, 6th, 12th month IOP, VA, medication use, complete success (CS) (5 ≤IOP ≤18 mmHg without medication and no additional surgical intervention), qualifi ed success (QS) (5 ≤IOP ≤18 mmHg with or without medication) and complications were evaluated. Results: The mean age was 72.3±13.4 (30-86) years; the mean follow-up time was 16.6±3.4 (12-24) months. The mean pre-op IOP was 31.34±8.18 (23-53) mmHg, fi rst month 14.76±5.85, 6th month 14.28±3.62, and 12th month 14.00±4.07 mmHg. Mean IOP reduction was statistically signifi cant in all post-op examinations (P<0.01). Drop in mean IOP was 55% approximately in the 12th month. The mean number of pre-op medications was 3.52±0.51; it decreased signifi cantly to 0.95±1.28 in the 12th month (P<0.01). Pre-op VA was 0.51±0.66, and the 12th month was 0.44±0.72 logMAR. This difference was no statistically signifi cant (P= 0.2). CS rate was 57%, and the QS rate was 90.5% in 12th months. The complication rate was 14% (3/21) Conclusion: Ex-PRESS shunt surgery in pseudophakic eyes with OAG is effective and safe with low complication rates in reaching target IOPand decreasing antiglaucomatous drug use.
