Abstract

Purpose: To further investigate the inflammatory response as one of the leading factors in the development of delayed limbal stem cell deficiency, clinically manifested by corneal neovascularization , following sulfur mustard ocular exposure in rabbits and to evaluate potential therapy. Materials and methods: Right eyes of rabbits were exposed to sulfur mustard vapor. Clinical examination was performed and the growth of corneal blood vessels was evaluated. Inflammatory cells (neutrophils, macrophages, antigen-presenting cells and T cells) were identified immunohistochemically. Tacrolimus (Prograf, Teva, 5mg/ml) an immuno-modulator drug, was tested via sub-conjunctival injection (50µl), started either before or after the development of neovascularization (72h and 4weeks, respectively) given once a week for 3weeks.
