Postoperative Recurrence Rate of Superior-Inferior Sliding Conjunctival Flap and Mytomycin-C for the Treatment of Primary Pterygium

• Kang BN

Abstract

One of the major problems after pterygium removal are recurrence and complications of the adjunctive therapy. The author compared the recurrence rate, interval and age of the primary pterygium after surgical treatment and with(group 1:94 eyes) or without(group 2: 101 eyes) supple-mentary mitomycin-C therapy. All of whom had been treated by one surgeon using a pterygim and subconjunctival tissue removal and superior-inferor, sliding conjunctival flap to cover the pterygium defect, In group 1, supplementary mitomycin-C was topicall used. In group 1, three pterygia(3.2%) were recurred. Recurrence were more Likey after ealy polstperative wound disruption with flap retraction(2 of 3 recurrences), relativy uoung pationts(all recurrences are under 50), and recurrence occured at a mean interval of 3.8 months after surgery. In group 2, three pterygia(3.0%) were recurred. Recurrencd were monre likely after early postoperative wound disruption with flap retraction(all recurrences). young patients(all recurrences are under 45), and recurrence occured at a mean interval of 3.1 months after surgery. Between two group no significant difference in recurrence rate, age, and interval so pterygium surgical procedure, operator and early postoperative conjunctival flap state are more important factors than adjunctive therapy in recurrence.
