Repair of an Inadvertent Buttonhole or Leaking Filtering Bleb

Abstract
• Buttonholing of conjunctival flaps at the time of filtering glaucoma surgery or a leak in the flap postoperatively can cause serious problems and may be most difficult to repair. A new delicate atraumatic needle has been used successfully in five cases to close conjunctiva to conjunctiva or conjunctiva to cornea defects.
