To evaluate the outcomes of Ahmed glaucoma valve implantation for therapy of glaucoma after penetrating keratoplasty. 17 Ahmed glaucoma valve implants were placed in 17 eyes with glaucoma after penetrating keratoplasty. The follow up was 1 year. V.A., IOP and index medication were observed before and 1 year after surgery. The mean preoperative IOP was 29.1 mmHg (+/-6.5) with average medication 2.65 +/- 0.5, 1 year after surgery the mean IOP decreased to 18.4 mmHg +/- 4.7 with 0.7 +/- 0.8 medication. The tube implant successfully controlled glaucoma in 13 eyes (73.5%) at 1 year. The corneal grafts remain clear in 11 eyes (64.7%). Implantation of Ahmed glaucoma valve successfully controlled IOP in difficult cases of glaucoma after penetrating keratoplasty.
