Abstract

AB-interno Canaloplasty (ABiC) is one of the minimally invasive glaucoma surgeries for patients with Primary Open-Angle Glaucoma (POAG). The main mechanism is the enlargement of Schlemm’s canal and the collector channels. There is less research on its unsuccessful rate and the possible reasons. Here we report 2 cases of elevated intraocular pressure and blockage of Schlemm’s Canal (SC) orifice after ABiC surgery. We speculate that the reason for the failure is that the iris adhesion blocks SC orifice. Considering the effectiveness of internal drainage in 2 cases and the need to solve the problem of iris adhesion effectively, we performed a new procedure, which called penetrating canaloplasty, it is combining canaloplasty with trabeculectomy, iridectomy, but tightly closed the scleral flap. We speculated that aqueous humor through the SC orifice is a direct drainage way in ABiC to decrease the IOP, and iris adhesion may be the possible cause of the failure of part of SC surgery, and penetrating canaloplasty can be an option for patients after ABiC surgery.
