Purpose: To report the early results of transplantation of autologous limbal stem cells cultivated on amniotic membrane (AM) in patients with total unilateral limbal stem cell deficiency (LSCD). Methods: Four eyes of 4 patients with total unilateral LSCD confirmed with impression cytology underwent transplantation of autologous limbal stem cell cultivated on AM. At each follow up visit, a compl...

purpose: to investigate the efficacy of limbal-conjunctival autografting technique in patients with primary pterygium methods: fifteen eyes of 15 patients with primary pterygium underwent surgery for the removal of pterygium with limbal-conjunctival autograft. after the pterygium excision, the limbal portion of the graft was oriented and sutured to the limbus at the recipient bed with the epith...

Limbal Stem Cell Deficiency (LSCD) is an eye disease that can cause corneal opacity and vascularization. In its advanced stage it lead to a degree of visual impairment. It involves the changing in semispherical shape cornea drooping downwards direction. LSCD hard be diagnosed at early stages. The color texture surface provide significant information about affected by LSCD. Parameters such as ar...

PURPOSE Limbal stem cell deficiency is a challenging clinical problem and the current treatment involves replenishing the depleted limbal stem cell (LSC) pool by either limbal tissue transplantation or use of cultivated limbal epithelial cells (LEC). Our experience of cultivating the LEC on denuded human amniotic membrane using a feeder cell free method, led to identification of mesenchymal cel...

PURPOSE To develop a mouse model of limbal stem cell deficiency (LSCD) by topical administration of benzalkonium chloride (BAC). METHODS BAC solutions (0%-0.5%) were applied to the mouse ocular surface for 4 weeks. Corneal neovascularization, inflammation, and epithelial status were observed under slit-lamp microscope. The eyeball and ocular surface tissues were collected at 4 and 12 weeks an...

PURPOSE To investigate the potential of a pigment epithelial-derived factor (PEDF) peptide 44-mer to promote limbal regeneration in a rabbit partial limbal deficiency model. METHODS Limbal excision (180°) was created surgically, and topical application of 44-mer-containing ointment once a day for 2 weeks was started immediately after injury. Limbal barrier function was inspected at 2 and 6 mo...

PURPOSE Limbal epithelial stem cell deficiency is caused by exposure of the cornea to thermal, chemical, or radiation burns or by diseases (aniridia and Stevens-Johnson syndrome). Autologous cell transplantation is a widely used therapeutic modality for restoring the corneal surface in such pathological conditions. Ex vivo cultured limbal, conjunctival, and oral biopsies have been widely used t...
