TitelClinical outcomes of Ahmed Glaucoma Valve in posterior segment
DoelTo study intermediate-term intraocular pressure (IOP) control and complication profile of the Ahmed Glaucoma Valve (AGV) implanted posteriorly through the pars plana in eyes undergoing concurrent pars plana vitrectomy (PPV)
MethodesWe retrospectively reviewed the medical records of 19 cases eyes (19 patients) with refractory glaucoma that underwent posterior implantation of AGV after complete PPV and compared the clinical post-operative outcome to the pre-operative status.
This posterior route was preferentially indicated because of higher risk of decompensated cornea and tube extrusion in the patient population. All surgeries were performed by the same surgeons using a silicone-plate device (FP7).
Success was defined as intraocular pressure (IOP) ≥ 5 mmHg and ≤ 21 mmHg with or without glaucoma medications at final follow-up, no additional glaucoma surgery, no removal of the implant, and no loss of light perception.
ResultatenThe average follow-up was 12 months (range: 8 to 24 mo). The reduction in IOP was statistically significant at all postoperative time points (Pre-IOP: 30,31 mmHg - 12 months IOP: 15,2 mmHg). The number of postoperative glaucoma medications was statistically reduced at final follow-up (Pre-op: 2,85 to post-op: 1,7). Success rate at final follow-up were 84%. Postoperative complications were observed in 9 patients and spontaneously resolved without any further surgery except for one.
ConclusieCombined 25-Gauge vitrectomy and posterior tube shunt placement is a safe and useful option in eyes with secondary refractory glaucoma.
