Trabeculotomy ab interno with internal limiting membrane forceps for open-angle glaucoma

Purpose To describe a new technique to perform trabeculotomy ab interno on eyes with open-angle glaucoma (OAG). Methods This was a retrospective study. We inserted a 25-gauge forceps that is usually used for internal limiting membrane peeling into the anterior chamber, and grasped and pulled the inn...

Description
Summary:Purpose To describe a new technique to perform trabeculotomy ab interno on eyes with open-angle glaucoma (OAG). Methods This was a retrospective study. We inserted a 25-gauge forceps that is usually used for internal limiting membrane peeling into the anterior chamber, and grasped and pulled the inner wall of Schlemm’s canal away from the canal. The inner wall of Schlemm’s canal was stripped for about 100° to 120° in 26 eyes of 23 patients. The intraocular pressure (IOP) and number of glaucoma medications were recorded before, and 1 day, 1 week, 2 weeks, and 1, 3, 6, 10, 12, 15, 17, 19, 24, 27, 30, and 33 months after the surgery. The intra- and postoperative complications were recorded. Results The mean ± standard deviation of the preoperative IOP was 20.0 ± 6.8 mmHg with a range from 10 to 38 mmHg ( n  = 26). The IOP was significantly reduced ( P
