Efficacy of Cultivated Corneal Epithelial Stem Cell for Ocular Surface Reconstruction

December 5, 2011 updated by: Pinnita Prabhasawat, Mahidol University
The purpose of this study is to elucidate the appropriate condition of developing cultivated corneal epithelial graft and evaluate the surgical outcome of transplantation of the cultivated corneal epithelial stem cell in the patients.

Detailed Description

Ocular surface damage caused by severe ocular surface diseases, particularly thermal and chemical burn or Stevens-Johnson syndrome result in corneal epithelial defect, corneal vascularization, corneal conjunctivalization and loss of transparency. Corneal limbal stem cell transplantation has been demonstrated to improve the outcome of ocular surface reconstruction. However, the conventional management of allograft limbal transplantation generally has unsatisfactory outcome because of high risk of rejection and requires long-life immunosuppressive medications.
