Endothelial keratoplasty has become the standard of care for corneal endothelial dysfunction. In recent publications previous glaucoma surgery was associated with a significantly increased rate of graft dislocation compared with eyes which did not undergo a prior glaucoma surgery. We aimed to describe a patient with a prior trabeculectomy surgery who underwent Descemets stripping automated endothelial keratoplasty (DSAEK). The patient had graft dislocation and underwent graft repositioning twice.
Department of Ophthalmology, Meir General Hospital
We describe herein a 60 year old glaucoma patient with pseudophakic bullous keratopathy who underwent uneventful DSAEK
No intraoperative complications were seen. One day post-operatively graft dislocation was noted associated with normal intraoperative pressure. The graft was repositioned and rebubbled successfully, but on postoperative day 2 it was dislocated again. On slit lamp examination air bubbles were noted in the filtering bleb site. Thus, immediately after a second graft repositioning the patient was put in a supine Trandelenburg position. Few hours later the graft was adherent and well-centered.
Previous trabeculectomy is associated with a significantly increased rate of graft dislocation. Trandelenburg positioning may prevent air escape to bleb site and decrease graft dislocation rate in patients with prior trabeculectomy/ glaucoma drainage device surgery.
