Cytological features of live limbal tissue donor eyes for autograft or allograft limbal stem cell transplantation.
PURPOSE To evaluate by impression cytology (IC) the corneal surface of live limbal tissue donor eyes for autograft or allograft limbal stem cell transplantation (LSCT). METHODS Twenty limbal donors were enrolled (17 for autograft LSCT and 3 for allograft). Impression cytology was performed before transplantation of superior and inferior limbal grafts and after the third postoperative month. ...
متن کاملMinimal conjunctival limbal autograft for total limbal stem cell deficiency.
PURPOSE To report the results of one 60 degrees conjunctival limbal autograft (CLAU) combined with amniotic membrane (AM) transplantation for an eye with total limbal stem cell deficiency (LSCD). METHODS One eye of a patient with chronic total LSCD and symblepharon caused by chemical burn was subjected to symblepharon lysis, removal of pannus from corneal surface, AM transplantation to cover ...
متن کاملLimbal stem-cell transplantation.
Cornea epithelium is subject to constant trauma and shedding of the surface epithelium, and replenishment is from epithelial cells beneath and peripheral to the central desquamating epithelium. The origin of the corneal epithelium appears to reside in the crypts of Vogt, where a population of "immortal" stem cells resides, possessing enormous potential for clonogenic cell division. These cells,...
متن کاملSclerocorneal limbal stem cell autograft transplantation in dogs
The effects of sclerocorneal limbal stem cell autograft transplantation in dogs with corneal wounds were studied. Eighteen dogs were divided in two groups (GI and GII). The animals of GI (n=12) underwent limbal transplantation 30 days after the destruction of limbal stem cells. The dogs of GII (n=6) only underwent destruction of stem cells (control group). Light microscopy examination of the ri...
متن کاملLate Acute Rejection After Allograft Limbal Stem Cell Transplantation: Evidence for Long-Term Donor Survival.
PURPOSE To describe the clinical presentation and management of late (>3.0 years) acute graft rejection in keratolimbal allograft (KLAL) recipients. METHODS This was a multicenter, retrospective observational case series. Six eyes of 6 patients with ocular surface transplant at a mean age of 36.2 years were seen at 3 tertiary referral centers for acute graft rejection between 2007 and 2013. M...
