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 IOP and decreasing antiglaucomatous drug use.
