The comparison of the recurrence rates after pterygium excision combined with conjunctiva and with amnion transplantation

Abstract

Objective To compare the recurrence rates after pterygium excision combined with autologous conjunctiva and amniotic membrane transplantation. Methods One hundred and thirty eyes of one hundred and eight patients who underwent pterygium surgery were randomly divided into group A and group B. Patients in group A received pterygium excision combined with autologous conjunctiva transplantation, including 70 eyes of 58 patients; and patients in group B received pterygium excision combined with amniotic membrane transplantation, including 60 eyes of 50 patients. All patients were followed up for 1 year. The tear film stability(breaking up time) and recurrence rates were recorded and analyzed. Results One year after the surgery, 8 eyes (11.42%) in group A had recurrent pterygium, and 14 eyes (23.33%) in group B had recurrent pterygium. The difference in recurrence rate between the two groups was statistically significant (P 0.05). Conclusion Pterygium excision combined with autologous conjunctiva transplantation can make lower recurrence rate than pterygium excision with amniotic membrane transplantation.
