Abstract:

As a non-penetrating glaucoma surgery (NPGS), canaloplasty aims to restore the physiological outflow by dilating the Schlemm’s canal, thus facilitating aqueous outflow to treat glaucoma. Evolving from traditional canaloplasty, ab-interno canaloplasty (ABiC) is a new minimally invasive glaucoma surgery (MIGS) procedure that can comprehensively restore the natural outflow pathways in patients with mild-to-moderate primary open angle glaucoma. Canaloplasty represent a truly effective and excellent safety profile for reducing intraocular pressure with or without combining with other surgeries. Canaloplasty is non-bleb related with no filtering blebs which were detected a low rate of bleb-related complications such as scar formation and encapsulation. Canaloplasty has satisfactory intraocular pressure lowering effects in high efficiency and security. (Int Rev Ophthalmol, 2018, 42: 78-82)
