PRÉCIS: Previous trabeculectomy and medical or surgical glaucoma treatment after Descemet's stripping automated endothelial keratoplasty (DSAEK) were significantly associated with endothelial cell loss and graft failure. The pupillary block was a significant risk factor for graft failure.
PURPOSE: To evaluate the long-term risk factors associated with postoperative endothelial cell loss and graft failure after DSAEK in Japanese eyes, with special attention to glaucoma.
PATIENTS AND METHODS: This retrospective study involved 117 eyes of 110 consecutive patients with bullous keratopathy who had undergone DSAEK. The patients were classified into 4 groups: (1) no glaucoma group (n = 23 eyes), (2) primary angle closure disease group (n = 32 eyes), (3) glaucoma group that had previously undergone trabeculectomy (n = 44 eyes) (glaucoma with bleb), and (4) glaucoma group that had not previously undergone trabeculectomy (n = 18 eyes) (glaucoma without bleb).
RESULTS: The cumulative 5-year graft survival rate was 82.1%. The cumulative 5-year graft survival rate among the 4 groups is as follows: no glaucoma (73%), primary angle closure disease (100%), glaucoma with bleb (39%), and glaucoma without bleb (80%). Multivariate analysis revealed that additional glaucoma medication and glaucoma surgery after DSAEK were independent risk factors for endothelial cell loss. Conversely, glaucoma with blebs and pupillary block were independent risk factors for graft failure after DSAEK.
CONCLUSION: Previous trabeculectomy and medical or surgical glaucoma treatment after DSAEK were significantly associated with endothelial cell loss and graft failure. Pupillary block was a significant risk factor for graft failure.
