Surgical Outcomes of the Ahmed Valve Implantation Following Trans-scleral Cyclophotocoagulation

Purpose: To determine the intraocular pressure (IOP) lowering effect and complications of Ahmed valve implantation (AGV) in patients who underwent cyclophotocoagulation (CPC).Methods: Patients AGV after CPC group 1, those 2, repeated 3 were included this retrospective observational study. Changes IOP, number glaucoma eye drops, best corrected visual acuity (BCVA) analyzed before 1 week, month, months, 6 12 months surgery, postoperative analyzed.Results: Eight 10 seven analysis. Preoperative IOP was 45.6 ± 15.5, 29.3 5.6, 43.4 14.4 mmHg three groups, respectively, drops 3.8 0.7, 3.9 0.3, 3.7 1.0 respectively. At postoperatively, decreased significantly all groups compared to preoperatively (all <i>p</i> < 0.05), also reduced 0.05). Among with preoperative BCVA 0.02 decimal or higher, two 2 one (<i>p</i> = 0.380). Hypotony occurred patient 0.383), among them, progressed phthisis 0.940).Conclusions: In whose cannot be controlled CPC, is expected used as a relatively safe effective treatment method for IOP.
