View clinical trials related to Corneal Transplant Rejection.
Filter by:The goal is to develop a nationwide registry to track longitudinal clinical outcomes of and store imaging data related to numerous corneal conditions. There are two main objectives including the establishment of the first nationwide corneal transplant registry in the United States to include information related to the donor tissue, recipient, surgical procedure, and long-term clinical outcomes. Ultimately, this prospective data collection will allow us to determine prognostic factors for successful corneal transplantation and create an algorithm to guide clinical practice based on real world outcomes. The second objective is to collect and create a database of historical, de-identified optical coherence topography (OCT) and corneal topography images to ultimately develop artificial intelligence (AI) based diagnostic and prognostic algorithms for corneal disease and surgery.
Keratoplasty is one of the most common grafts and penetrating keratoplasty is still the technique most used in the world, ahead of lamellar grafts, and is estimated to represent 70% of the total. Graft rejection is still the main cause of failure of this type of surgery, to the extent that nearly a third of all patients will in some way be affected by rejection in due course. Numerous risk factors for rejection have been identified, whether related to the donor, the recipient, or the surgical procedure itself. In addition, many of the studies performed have used univariate analysis only, and yet there is a strong case for multivariate analysis, given the wide range of factors that need to be examined. This study seeks to analyze the rejection rates and the survival of penetrating keratoplasty for a group of patients from Montpellier Hospital (France).
