title: [Implantation of Ahmed-type valve in the treatment of glaucoma, following penetrating keratoplasty].
abstract: OBJECTIVE
  To evaluate the outcomes of Ahmed glaucoma valve implantation for therapy of glaucoma after penetrating keratoplasty.
  
  
  METHODS
  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.
  
  
  RESULTS
  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%).
  
  
  CONCLUSIONS
  Implantation of Ahmed glaucoma valve successfully controlled IOP in difficult cases of glaucoma after penetrating keratoplasty.
