PURPOSE: Description and evaluation of the technique and efficacy of canaloplasty ab interno (ABIC) in patients with open angle glaucoma (POAG). METHODS: In this monocentric series of consecutive cases, patients with cataract and open angle glaucoma (combined operation) and pseudophacic patients (mean age: 78 years, range 66-90 years), and suffering from POAG were included. All of them were operated with ABIC by using the iTrack™ 250 µ-microcatheter (Ellex Medical Lasers Pty Ltd, Adelaide, Australia), in order to circumferentially vasodilate Schlemm's canal without implanting a suture to increase tension. Primary endpoints were the mean IOP (intraocular pressure) after 1, 3, 6, 9 and 12 months surgery. RESULTS: Twenty-three patients (23 eyes) were included in the study. Mean IOP without a preoperative wash-out phase was reduced from 18.8 ± 5.63 mmHg preoperatively to 14.9 ± 2.90 mmHg (n = 22), 13.82 ± 2.98 (n = 19), 14.69 ± 2.36 mmHg (n = 13), 16.0 ± 2.09 (n = 11) and 14.73 ± 2.97 (n = 11) at 1, 3, 6, 9 and 12 months after surgery. Mean medication was reduced from 1.69 to 0.21 at the last follow-up. The only complication was limited descemetolysis near the limbus. CONCLUSION: The initial results in this study indicate that ABIC reduces IOP and that the dependance on medication is comparable to that with ab externo canaloplasty.
