Seton implantation has become increasingly useful in the surgical management of glaucoma.1 Complications of this surgery include those common to any filtration surgery, such as cataract, choroidal effusion or hemorrhage, early or late endophthalmitis, retinal detachment, or Tenon cyst and others unique to the presence of an implanted foreign body, such as extrusion or late erosion through the overlying sclera and/or conjunctiva and Tenon's fascia.1 A single case of early postoperative endophthalmitis has also been reported.2 We treated two patients for late endophthalmitis following external erosion of the implant through the conjunctiva. To our knowledge, this complication has not been previously reported.
