Results Single center retrospective chart review Medical records of 65 eyes of 62 patients underwent primary pterygium surgery with fibrin glue over a 5 month period (between April to September 2005). 30 / 62 (46%) were females. The median age of this cohort was 53 years (range 31-81 years). The mean follow-up time was 9.5 months (range 9 to 14 months). A Free sample background from www.awesomebackgrounds.com Slide 27 © 2003 By Default! RESULTS There were no intraoperative complications. Post operatively conjunctival graft displacement was noted in 2/65 eyes (3.1%). At 9 ½ months followup there was no evidence of recurrence that required repeat surgery.
