The Clinical Results of Limbal Conjunctival Autograft Transplantation with Intraoperative Mitomycin C Application for Recurrent Pterygia

ABSTRACT

The recurrence is common problem to treat pterygium. Many surgical procedures were adopted to reduce the recurrence rate. We evaluated the surgical results of limbal conjunctival autograft transplantation (LCAT) accompanying application of 0.02% mitomycin C intraoperatively in 10 patients (10 eyes) who had a recurrent pterygium. There were 7 eyes with first recurrence and 3eyes with second recurrence. Mean age of the patients was 57.4 years, and mean follow-up period was 9.3 months. After a pterygium was excised, a sponge soaked in a solution of mitomycin C 0.02% was applied to the sclera at the site of the surgical bed for 2 minutes, then superior temporal limbal tissue was taken with conjunctival flap and transplanted to the excised area. None of all cases recurred for follow-up period and donor conjunctival site was well reepithelialized. In concluion, LCAT accompanying application of 0.02% mitomycin C intraoperatively was effective and safe method for recurrent pterygium.
