Abstract: | Purpose: To investigate and compare the efficacy of amniotic membrane transplantation, corneal limbus stem cell conjunctival transplantation and pedicle conjunctival flap transposition in the treatment of pterygium. Methods: A total of 155 patients with pterygium were retrospectively analysed: 53 cases who received amniotic membrane transplantation, 41 who underwent corneal limbus stem cells conjunctival transplantation, and 61 patients who had pedicle conjunctival flap transposition. Results: Patients in the three groups had no significant differences in terms of age, times since surgery, or extent of pterygium extension onto the cornea (F:1.194, 0.639, 0.140 respectively; all P>0.05). A total of 137 out of 155 patients (88.4%) completed 6 months of follow up. The recurrence rates of pterygium for the three surgeries (amniotic membrane transplantation, corneal limbus stem cells conjunctival transplantation and pedicle conjunctival flap transposition) were 14.6%, 13.9% and 7.7%, respectively. No significant difference was identified when comparing the recurrence rate between any two groups (X2: 0.008, 1.211 and 0.890; P: 0.593, 0.218 and 0.276). Five patients presented with postoperative complications, including 3 cases of sub-conjunctival hemorrhage, 1 case of amniotic membrane dissolution, and 1 case of conjunctival cyst, accounting for 3.64% of all participants. Conclusion: These three surgical methods are equally effective in preventing the recurrence of pterygium after excision. |
