Repair of an inadvertent buttonhole or leaking filtering bleb
G. J. Petursson and F. T. Fraunfelder
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.
