Amniotic membrane transplantation for ocular surface reconstruction.

ABSTRACT

OBJECTIVE: To study the efficacy of amniotic membrane transplantation in various indications for ocular surface reconstruction. METHOD: Amniotic membrane transplantations were performed in 140 eyes (130 patients) for ocular surface reconstruction. The indications for the corneal group were limbal stem cell deficiency, bullous keratopathy, persistent epithelial defect, band keratopathy, prosthesis, corneal ulcer and acute chemical burn. The indications for the conjunctival group were grafts for pterygium, conjunctival tumors, symblepharon, and covering the scleral graft. RESULTS: Success was noted in 75.7 per cent (106/140) eyes, partial success in 17.9 per cent (25/140) eyes, and failure in 6.4 per cent (9/140) eyes for a mean follow-up of 6.6 months (1-19 months). The success and partial success rate were 80.6 per cent (54/67), 14.9 per cent (10/67) in the corneal group and 71.2 per cent (52/73), 20.6 per cent (15/73) in the conjunctival group. CONCLUSION: Amniotic membrane transplantation can solve some difficult ocular surface problems, and can be used to promote epithelial healing, reduce inflammation and scarring.
