Abstract Details

Purpose:

The aim of this study was to evaluate the postoperative results after Descemet Stripping Automated Endothelial Keratoplasty (DSAEK) in eyes presenting endothelial decompensation associated with glaucoma drainage implants with anterior chamber (AC) tube placement. Graft dislocation, frequency of primary and secondary failure and intraocular pressure control were assessed.

Setting:

Hospital dos SAMS, Lisboa. Portugal

Methods:

This is a retrospective study of the first 10 eyes of 8 patients who had undergone DSAEK after glaucoma surgery with drainage implant and anterior chamber (AC) tube placement. All patients were operated between January 2011 and June 2015 by the same DSAEK surgeon (JF) after being operated by the same glaucoma surgeon (MC). A longer follow up time was chosen in detriment of a more numerous sample.

Results:

Postoperative follow-up has shown good graft adherence to the recipient's stroma, no graft dislocation, no primary failure, controlled intraocular pressure in all cases and clear corneal grafts in 7 cases. There was secondary failure in 4 cases, two of which occurring in the same eye.

Conclusions:

Endothelial transplants are currently the preferential approach in the surgical treatment of endothelial pathology, especially Fuchs's dystrophy and pseudophakic bullous keratopathy. Despite the higher risk of graft dislocation and secondary failure, DSAEK should also be considered as the first option to manage the endothelial decompensation associated with glaucoma surgery with drainage implant and AC tube placement. These cases present an additional challenge for the DSAEK surgeon.
