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.

Keratitis by Fusarium temperatum, a novel opportunist.

Background: Fusarium species are among the most common fungi present in the environment and some species have emerged as major opportunistic fungal infection in human. However, in immunocompromised hosts they can be virulent pathogens and can cause death. The pathogenesis of this infection relies on three factors: colonization, tissue damage, and immunosuppression.

Use of irradiated human amnion as a matrix for limbal stem cell culture.

Several ocular diseases affect the corneal surface; the development of effective technologies for the treatment of corneal lesions has brought about an improvement in the quality of life of affected patients. The aim of this study is to culture and characterize limbal stem cells cultured on gamma ((60)Co) radiosterilized human amnion (RHA). Limbal stem cells were isolated from ten preserved samples of corneal transplant.
