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 ...
Corneal opacification associated with glycosaminoglycan (GAG) deposition occurs in canine mucopolysaccharidosis I (MPS I), a deficiency of the lysosomal enzyme alpha-L-iduronidase. In affected dogs corneal lesions appear similar to those in children with the same disease. Transplantation of bone marrow from unaffected littermates was performed in 5 MPS I affected dogs at 5 months of age. In thr...
Organ retrieval provides a service to both recipients and donor families. Many patients and their families wish to donate organs at the time of death and eye donation is rarely contraindicated. Corneal transplantation is a commonly performed procedure in Canada and is done either to restore sight or eye integrity. Corneal scarring, degeneration and dystrophy, keratoconus and keratoglobus are co...
Purpose CD4+LAP+ T cells are newly discovered regulatory T cells (Tregs). The aim of this study is to investigate the balance of Th1/Th2 and LAP+Tregs/Th17 in mice after allogeneic corneal transplantation. Methods A total of 65 mice received orthotopic penetrating transplantation. According to the survival scores of the grafts, the mice were divided into the rejection group and the survival g...
The most difficult part in ocular surface reconstruction for total limbal stem cell deficiency is restoring a healthy and stable corneal epithelium. Recently, there has been a shift toward a cellular-based transplantation that eliminates the need for harvesting large amounts of limbal tissues from a living donor. The autologous oral epithelium can be used as a source for ocular surface reconstr...
The existing acute shortage of good quality donor corneas in a developing country like India, prompted us to attempt customised component corneal transplantation. Using this surgical strategy, one corneoscleral button was used for three recipients. Anterior and posterior lamellar discs were used for anterior lamellar keratoplasty and Descemet's stripping endothelial keratoplasty in patients wit...
