Purpose: To investigate the clinical outcomes of primary pterygium excision combined with free conjunctival autograft.
Methods: The medical records of 112 patients (129 eyes) who underwent pterygium excision and free conjunctival autograft for primary pterygium were retrospectively reviewed for recurrence and postoperative complications and the outcomes compared with pterygium excision combined with amniotic membrane transplantation, conjunctival flap, or simple conjunctival closure. Additionally, the surgical outcomes were evaluated in relation to the intraoperative use of mitomycin C.
Results: Postoperative recurrences were observed in 3 of 129 eyes (2.3%) that received pterygium excision and free conjunctival autograft, 2 of 10 eyes (20.0%) that received pterygium excision with amniotic membrane transplantation, 1 of 10 eyes (10.0%) that received pterygium excision with conjunctival flap and 1 of 12 eyes (8.3%) that received pterygium excision and simple conjunctival closure. Therefore, the recurrence rate was significantly lower in patients with conjunctival autograft than in those without (p = 0.024, Breslow-Wilcoxon test). Additionally, recurrence was observed in 1 of 10 eyes (10.0%) in patients that underwent pterygium surgery when mitomycin C was used intraoperatively and in 2 of 119 eyes (1.7%) without the use of mitomycin C.
Conclusions: Pterygium excision combined with free conjunctival autograft is an effective and safe surgical procedure to treat primary pterygium.
