Abstract:
AIM: To investigate the efficacy, safety and localization of multilayer amniotic membrane transplantation (AMT) for the management of corneal perforation associated with ulceration.METHODS: Six eyes (6 patients) were treated with multilayer AMT for corneal perforation associated with ulceration. The perforation size was 0.5-2mm in diameter. The amniotic membrane (AM) was applied to tamp the perforation, fill the ulcer and cover the surface of ulcer. The follow-up ranged from 5-19 months.RESULTS: The anterior chamber reformed at the first postoperative day in all patients, and kept in normal depth in the follow- up time. The epithelialization of the AM grafts was observed in about 3 weeks after surgery. During the first postoperative month, the corneal thickness at the perforation site gradually increased, and the stromal inflammatory cell invasions surrounding the corneal ulcer were gradually subsided.Two months postoperatively, the ulcer healed with scar with part neovascutarization; the corneal thickness of the ulcer area was stable and recovered almost normal. The vision was not improved in all patients after operation. During-follow up,no severe complications or recurrence of ulceration was noted.CONCLUSION: Multilayer AMT is an effective and safe method for the management of small corneal perforation associated with ulceration, but the ulcer healed with scar.
