Clinical trial of three treatment methods for pterygium

摘要

Objective: To study the effect of simple excision, amniotic membrane transplantation(AMT) and limbal-conjunctival autograft transplantation (LCAT) for treating pterygium. Methods: Forty-eight cases (48 eyes) with pterygium were randomly assigned to 3 groups: 16 cases (16 eyes) with pterygium underwent simple excision (group A), 16 eyes underwent amniotic membrane transplantation (AMT) (group B), and 16 eyes with pterygia underwent limbal- conjunctival transplantation (group C). Results: With follow-up of 3 months to 25 months, 5 cases (31%) of pterygia in group A and 1 case (6. 2%) of pterygia in group B showed recurrence. No patients in group C developed recurrence. Conclusion: The recurrent rate of pterygium after amniotic membrane transplantation and limbal-conjunctival autograft transplantation were much lower, but the latter was more simple, safe and no rejection . So limbal - conjunctival autograft transplantation is the best surgery method for pterygium.
