To evaluate the recurrence rate and safety of amniotic membrane transplantation (AMT) augmented with mitomycin C (MMC) compared with amniotic membrane transplantation alone during the pterygium excision. We took a meta-analysis on this program. Pertinent studies were selected through extensive searches of the Cochrane Library, MEDLINE, EMBASE, CBMdisc, CNKI. Pooled estimates were carried out in RevMan software v.4.2. Six trials reported postoperative recurrence rate of pterygium, included 882 eyes, three trials reported the complications. The results of meta-analysis showed that recurrence rate of AMT plus MMC group was 5.41%, AMT alone group was 16.89%, RR was 0.32, 95%CI ranged from 0.19 to 0.56, Z was 4.06, P<0.001. Two trials reported early complication as punctata keratitis, the incidence rate of AMT plus MMC group and AMT alone group were 17.14% and 0.00%, RR was 12.11, 95%CI ranged from 1.62 to 90.76. Amniotic membrane transplantation with MMC was associated with lower recurrence rate compared with amniotic membrane transplantation alone in pterygium excision, whether accompanied a higher risk with adverse events need more investigation.
