title: Technique for trouble-free removal of pars plana infusion cannulas.
abstract: We describe a simple procedure that facilitates the removal of a pars plana cannula. A 2-cm 4-O black silk suture is passed under the double-throw knot, which secures the infusion cannula. When the ends of the silk suture are pulled, the double-throw knot opens easily, allowing the cannula to be removed.
