Popis: AIM: To compare the surgical outcomes of glaucoma drainage device implantation (GDI) and trans-scleral neodymium:YAG cyclophotocoagulation (CPC) in the management of refractory glaucoma after Descemet-stripping automated endothelial keratoplasty (DSAEK). METHODS: This retrospective study on observational case series enrolled 29 patients who underwent DSAEK and posterior anti-glaucoma surgery (15 with GDI and 14 with CPC). The main outcome measures were intraocular pressure (IOP), glaucoma surgery success rate (defined as IOP of 6–21 mm Hg without additional anti-glaucoma operation), number of glaucoma medications, endothelial graft status, and best-corrected visual acuity (BCVA). RESULTS: The mean follow-up time was 34.1 and 21.0mo for DSAEK or glaucoma surgeries, both for the GDI and CPC groups. Both groups showed significant IOP reduction after glaucoma surgery. The GDI group presented a significantly higher success rate in IOP control than the CPC group (60% vs 21.4%, P=0.03). Both procedures significantly decreased the number of glaucoma medications (P=0.03). Forty percent and 57% of cases in the GDI and the CPC group, respectively, experienced endothelial graft failure during follow-up (P=0.36). Significantly worse BCVA after surgery was observed in the CPC group but not in the GDI group. CONCLUSION: Both GDI and CPC significantly decrease IOP in eyes with glaucoma after DSAEK. GDI is preferable to CPC in refractory glaucoma cases after DSAEK, as it manifests a significantly higher success rate for IOP control, similar endothelial graft failure rate, and relatively preserves BCVA than CPC.
