We performed a retrospective, observational clinical study to compare postoperative recurrence and symblepharon following excision of recurrent pterygium combined with amniotic membrane transplantation (AMT) according to intraoperative mitomycin C (MMC) application.
An analysis of 20 eyes of 19 patients who underwent recurrent pterygium surgery with AMT. Eight eyes received MMC intraoperatively, while the other 12 eyes did not. Recurrence rates and complications were evaluated.
Mean postoperative follow up was 19.8 months. Conjunctival recurrences were noted in 2 eyes and corneal recurrences were found in 3 eyes in AMT with MMC group (62.5%). Conjunctival recurrences were noted in 3 eyes and corneal recurrences were found in 4 eyes in AMT without MMC group (58.3%). There was no significant difference in recurrence rates (p = 0.91). In cases with preoperative symblepharon, symblepharon did not recur postoperatively in eyes with MMC, but postoperative symblepharons were noted in eyes without MMC. There was no significant complication in both groups.
The application of MMC was effective to prevent recurrent symblepharon, but had no significant effect on recurrence rates in excision of recurrent pterygium with AMT.
