Abstract Details

Purpose:

To evaluate the efficacy and safety of ABiC in patients with primary open-angle glaucoma (POAG) in combined and stand-alone surgery.

Setting:

Augencentrum K�Ã�¶ln-Porz, Germany

Methods:

22 Patients (mean age, 76 years; range, 66-83 years) underwent ABiC using the iTrack�â�„�¢ 250-micron microcatheter (Ellex Medical Lasers Pty Ltd, Adelaide, Australia) to circumferentially viscodilate and intubate Schlemm�â�€�™s canal without placement of a tensioning suture. The primary endpoints were mean intraocular pressure (IOP) and mean number of glaucoma medications at 1, 3, 6, 9 and 12 months postoperative.

Results:

Mean IOP reduced from 18.5 �Â�± 3.44 mm Hg preoperatively to 14.9 �Â�± 2 mm Hg (n=22), 13.8 �Â�± 2.98 (n=19), 14.7 �Â�± 2.36 mm Hg (n=13), 16,0 �Â�± 2.09 (n=11) ,14,7 +2,97 mmHg at 1, 3, 6 ,9 and 12 months postoperatively. The pre-OP IOP was measured without a wash-out phase. The mean number of medications was reduced from 2.4 preoperatively to 0.2 at the last follow-up visit. Limited descemetolysis near the limbus during the dilatation of Schlemm`s canal occurred in one patient. No other adverse events were reported.

Conclusions:

The findings from this study indicate that ABiC lowers IOP and medication dependency. Long-term follow-up in a large patient cohort is required to confirm the efficacy of this minimally-invasive glaucoma procedure
