To review the complications of penetrating keratoplasty (PK) with simultaneous insertion or repositioning of a glaucoma drainage implant (GDI) through the pars plana (PP).
The medical records of all patients who underwent PK and primary placement or repositioning of a GDI through the PP from April 1, 1997 through October 24, 2006 were reviewed for peri and acute post-operative complications. Acute complications were defined as complications arising during surgery or within 6 weeks postoperatively.
107 eyes of 104 patients were identified. PK and PP vitrectomy were performed with primary PP GDI insertion in 75 eyes and with tube repositioning from anterior chamber to PP in 32 eyes. Two additional eyes of two patients developed expulsive choroidal hemorrhages while undergoing PK and therefore GDI implantation was aborted. Other complications included retinal detachment (1), vitreous strands to the GDI requiring repeat vitrectomy (2), primary graft failure (1), and persistent epithelial defect (1). There were no reports of strabismus, wound dehiscence, or endophthalmitis.
PK with simultaneous PP GDI primary placement or repositioning demonstrates a low set of acute or perioperative complications similar to studies reporting anterior placement of a GDI.
