Purpose: To report surgical results of canaloplasty surgery for primary open-angle glaucoma (POAG) in Japanese patients. Methods: Eleven eyes of 9 POAG patients underwent canaloplasty surgery at Toyama University Hospital. Three eyes of 3 patients underwent canaloplasty alone and 8 eyes of 6 patients underwent canaloplasty combined with cataract surgery. Canaloplasty was performed with a 10-0 polypropylene tensioning suture and an iTrack(trademark) 250A microcatheter. All patients were followed up for 12 months. Changes in intraocular pressure (IOP) and postoperative complications were examined. Results: Mean preoperative IOP was 23.4 (plus or minus) 5.5 mm Hg. Mean number of antiglaucoma drops was 2.8 (plus or minus) 0.6 before canaloplasty and decreased to 1.2 (plus or minus) 0.8 at 12 months after canaloplasty (p < 0.01). Mean IOP decreased postoperatively, being 13.7 (plus or minus) 2.8 mm Hg at 1 month, 12.8 (plus or minus) 3.5 mm Hg at 3 months, 14.0 (plus or minus) 4.4 mm Hg at 6 months, and 15.0 (plus or minus) 4.1 mm Hg at 12 months. The most frequent postoperative complication was mild hyphema (45.5%), which disappeared within 14 days after surgery. Conclusions: Canaloplasty may be an alternative surgery for POAG patients to reduce IOP to a value of approximately 15 mm Hg.
