Introduction: To compare amniotic membrane transplantation (AMT) associated with narrow-strip conjunctival autograft versus conjunctival autograft alone for the treatment of recurrent pterygium. Methods: Prospective consecutive interventional study. Patients with recurrent pterygium were randomly divided into one of two groups; Group 1: patients undergoing AMT associated with autologous conjunctival graft, and Group 2: patients undergoing conjunctival autograft alone. Results: Of the 80 operated eyes included in this study, 39 (Group 1, mean patient age: 52.1 ± 11.7SD years) underwent AMT associated with narrow-strip conjunctival autograft and 41 (Group 2, mean patient age: 45.8 ± 12.9SD years) underwent conjunctival autograft alone. In Group 1, 6 eyes (15.4%) had grade-1 pterygium, 19 eyes (48.7%) had grade-2 pterygium, and 14 eyes (35.9%) had grade-3 pterygium. In the second group, 5 eyes (12.2%) had grade-1 pterygium, 18 eyes (43.9%) had grade-2 pterygium, and 14 eyes (35.9%) had grade-3 pterygium. No statistically significant difference was found between the two groups (P = 0.752). Of the 39 eyes in Group 1, recurrent pterygium was observed in 7 cases (17.9%). However, of the 41 eyes in Group 2, recurrent pterygium was observed in only 4 cases (9.75%). No statistically significant difference was found between the two groups (P = 0.2684). Conclusions: The results of this study indicate that conjunctival autograft alone might be a better surgical choice for the treatment of recurrent pterygia than combining it with AMT, however, this second option provides a good surgical alternative in cases where little conjunctival donor tissue is available.
