Abstract:
PURPOSE: To evaluate the clinical outcome of multilayer amniotic membrane transplantation (AMT) in the cornea which was perforated or had impending perforation due to corneal ulcer. METHODS: Human multilayer amniotic membrane transplantation were performed in patients with perforation or impending perforation of cornea due to herpetic keratopathy (2 eyes of 2 patients) and fungal ulcer (1 eye). The surgical procedure consists of the following steps: First, all cellular debris was carefully removed from the base and the walls of the ulcer and loosened epithelium. In addition 1 to 2 mm zone is created around the ulcer by removal of healthy, adherent epithelium overlaying the normal Bowman membrane. Depending on the depth and the configuration of the ulcer, three or more of small pieces of human amniotic membranes are stacked one above the others to fill the cavity of the ulcer. Finally, a larger piece of membrane is trimmed to cover the ulcer and then secured with interrupted 10-0 nylon suture. RESULTS: The corneal perforations were prevented and the stable ocular surface were achieved in all patients. CONCLUSIONS: Human multilayer amniotic membrane transplantation is a useful treatment prior to corneal transplantation and considered as an alternative treatment to keratoplasty for perforation or impending perforation of corneal ulcer.
