The Effect of Inferior Conjunctival Transposition Flap for Recurrent Pterygium

ABSTRACT

PURPOSE: In the present study, the effect of the inferior conjunctival transposition flap in patients with recurrent pterygium was evaluated. METHODS: This study included 60 patients (63 eyes) that received pterygium surgery with inferior conjunctival transposition flap and diagnosed with recurrent pterygium. The inferior conjunctival transposition flap obtained from lower bulbar conjunctiva was secured with 8-0 VICRYL® after removal of recurrent fibrovascular tissues. This study was retrospectively reviewed for recurrence and postoperative complications in patients with a minimum follow-up period over 6 months. RESULTS: The mean follow-up period was 5 years and 8 months (range; 6 months to 14 years). Corneal recurrence occurred in 4 eyes (6.3%) and conjunctival recurrence was observed in 2 eyes (3.1%) among a total of 63 eyes. Conjunctival recurrence was not the progressive type and limited to the limbus and suture site. One case of corneal recurrence required additional symblepharolysis and auto conjunctival graft. Although mild flap congestion, hemorrhage and granuloma were observed, these cases improved during the follow-up period. CONCLUSIONS: The inferior conjunctival transposition flap procedure can be regarded as an effective surgical treatment option for recurrent pterygium.
