Management of Post-Keratoplasty Glaucoma: A Literature Review
Glaucoma is the second leading cause of graft failure after graft rejection. Sustained elevations in intraocular pressure (IOP) can lead to corneal endothelial decompensation, graft failure and vision loss. Causes of glaucoma post-keratoplasty include steroid response, pupillary block, retained viscoelastic material, distortion of the trabecular meshwork or Schlemm’s canal, haemorrhage, lens protein leakage, secondary angle-closure from peripheral anterior synechiae, and pre-existing glaucoma. Close monitoring, coupled with prompt diagnosis and appropriate treatment of post-keratoplasty glaucoma are vital to the preservation of optic nerve function and a successful graft outcome.
