Effectiveness of Wide Excision of Subconjucntival Fibrovascular Tissue with Conjunctivo-Limbal Autograft in Pterygium Surgery

ABSTRACT

PURPOSE: To evaluate the efficacy of wide excision of subconjucntival fibrovascular tissue after conjunctivo-limbal autograft of primary and recurrent pterygium. METHODS: Sixty-five eyes of 59 patients underwent pterygium excision with conjunctivo-limbal autograft. Thirty-six eyes of 33 patients had wide excision of pterygium, 29 eyes of 26 patients did not have wide excision of pterygium. All patients underwent follow-up for more than one year. Complications, recurrence rate, and operation time were evaluated. RESULTS: With a minimum of one year of follow-up, there was no recurrence in either group. Six cases (17%) of subconjunctival fibrosis at the donor site, one case (3%) of subconjunctival neovascularization at the donor site, and one case (3%) of wound gapping at the recipient site were noted in the wide excision group. In the non-wide excision group, there were two cases (7%) of subconjunctival fibrosis at the donor site, one case (3%) of granuloma at the donor site, and one case (3%) of retention cyst at the recipient site. Mean operating time in the non-wide excision group (45.2 +/- 6.9 minutes) was significantly shorter than that in the wide excision group (62.4 +/- 6.2 minutes). CONCLUSIONS: Non-wide excision with conjunctivo-limbal autograft in pterygium surgery can be considered an effective treatment with shorter operating time than the wide excision method. Both of these methods show low recurrence rates and few complications for both primary and recurrent pterygia.
