Circumferential viscodilation of Schlemm’s canal for open-angle glaucoma: ab-interno vs ab-externo canaloplasty with tensioning suture

This paired eye study found ABiC to have comparable IOP lowering and glaucoma medication reduction to CP in open-angle glaucoma. This suggests ABiC may be a suitable method for improving aqueous outflow via the trabecular pathway. Further large-scale investigation is needed.
