Allogeneic Limbal Epithelial Transplantation Modified With Solid Platelet-Rich Plasma for Bilateral Limbal Stem Cell Deficiency

Purpose: To present successful management of bilateral limbal stem cell deficiency (LSCD) by using an allogeneic limbal epithelial stem cell transplantation together with solid activated platelet-rich plasma (PRP). Methods: A 59-year-old man with a history of bilateral LSCD due to penicillin-induced Stevens-Johnson Syndrome suffered from a lime corneal burn in his right eye, leading to a total LSCD with severely reduced visual acuity. After stabilizing the ocular surface, we performed an allogeneic limbal epithelial transplantation from a cadaveric donor using an autologous clot of PRP to cover the limbal grafts to nourish the ocular surface microenvironment. Results: At the first week after the procedure, the corneal epithelium had fully reepithelized. At month 3, visual acuity improved from hand motion to 20/70. Conclusions: In this case, this new modified procedure was a promising, easy-to-perform, apparently safe, and effective treatment option to enhanced epithelial wound healing in ocular surface diseases. To our knowledge, this is the first report describing the incorporation of solid PRP in limbal transplantation procedures.
