Non-Penetrating Deep Sclerectomy with Canalectomy

  Channels: Glaucoma | Posted 6/19/2009

Rafael Bohorquez, MD, begins the case by making a fornix-based conjunctival incision followed by a superficial scleral flap. Mitomycin C is applied for 3 minutes, after which the deep scleral tissue overlying Schlemm's canal is excised. Blunt Utrata forceps are used during the canalectomy to peel away the inner wall and endothelium of Schlemm´s canal and the juxtacanalicular trabeculum. Viscoelastic is left in the scleral bed as a space-maintainer. To complete the case, the superficial flap is left sutureless and the conjunctiva is secured with one to two 10/0 nylon sutures.
