PURPOSE: To study the efficacy and the safety of ultrasound biomicroscopy assisted canaloplasty in the treatment of open-angle glaucoma (OAG) METHODS: A prospective study of uncontrolled open-angle glaucoma patients, or patients with cataracts associated with controlled or uncontrolled OAG under maximal medical therapy who had been subjected to canaloplasty alone or combined with cataract surgery, respectively. Complications, Goldmann intraocular pressure (IOP) and mean number of drugs (ND) were evaluated at 1 day, 1 week, 1 month, and every 3 months. RESULTS: Thirty five surgeries were performed (11 canaloplasties, 24 phaco-canaloplasties). The mean IOP (mmHg) dropped from 24.5±5.1, in canaloplasty, and from 19.8±6.4, in phacocanaloplasty, preoperatively, to medium-low levels at all follow-up periods (13.5±1.0 and 11.0±4.2, at 1 year in canaloplasty and phaco-canaloplasty, respectively). The number of grugs used dropped from 3.3±0.5 before surgery to less than of 1 in all follow-up periods (0.5±0.8 at 1 year). The complications were 2 microruptures of the trabeculodescemetic window, 5 entries in the collector channels, 5 choroidal space/anterior chamber passages, 10 hyphemas, 3 hypotonies, one peripheral Descemet detachment, one intracorneal hematoma, two peripheral anterior synechia, one internal iris prolapse, and two suture extrusions to the anterior chamber. CONCLUSIONS: Ultrasound biomicroscopy assisted Canaloplasty, alone or combined, provided a sustained IOP reduction to medium-low levels, led to a decrease in the number of drugs and had a good safety profile, making this a good alternative to trabeculectomy.
