title: Comparison of Two Techniques for the Treatment of Recurrent Pterygium: Amniotic Membrane vs Conjunctival Autograft Combined with Mitomycin C.
abstract: OBJECTIVE
  To compare the results of amniotic membrane transplantation (AMT) combined with mitomycin C (MMC) to the results of free conjunctival autograft (CA) combined with MMC for the treatment of patients with recurrent pterygium.
  
  
  METHODS
  In this prospective study, 60 eyes of 55 patients with recurrent pterygium were included and randomly assigned into group I (n = 30) who underwent AMT combined with MMC (AMT-MMC) and group II (n = 30) who underwent CA combined with MMC (CA-MMC). During a mean follow-up of 27.2 ± 20.8 months, recurrence of pterygium, change in uncorrected visual acuity and complications (including pain, corneal, conjunctival or scleral changes) were analyzed and were compared between groups.
  
  
  RESULTS
  Five eyes of 5 patients were lost to follow-up and were removed from analysis. The mean age (p = 0.274), the mean follow-up (p = 0.063), the number of prior pterygium excision surgeries (p = 0.641) and the mean preoperative visual acuity (p = 0.959) were similar in both groups. Recurrence was seen in 2 eyes (8%) in AMT-MMC group and 4 patients (13.3%) in CA-MMC group (p = 0.531). Postoperative visual acuity (p = 0.237), change in visual acuity (p = 0.525), severe pain (p = 0.531) and epithelial defect lasting more than 5 days (p = 0.510) were similar in both groups.
  
  
  CONCLUSIONS
  Amniotic membrane combined with MMC has similar recurrence rate to CA combined with MMC, in patients with recurrent pterygium. Similar outcomes and complication rates make AMT-MMC a promising method for the treatment of recurrent pterygium cases.
