title: Sequential pterygium excision with conjunctival autograft in the management of primary double-headed pterygia.
abstract: OBJECTIVE
  The purpose of this study was to evaluate the efficacy of sequential pterygium excision with conjunctival autograft (PECA) in the management of double-headed pterygia.
  
  
  METHODS
  All patients who underwent a sequential PECA procedure for double-headed pterygia from 2004 to 2009 were included in this retrospective, noncomparative, interventional case series. The recurrence rate and visual outcomes after this procedure were determined.
  
  
  RESULTS
  Nine eyes of 8 patients with doubled-headed pterygia undergoing sequential PECA were identified. Of 18 PECA procedures, 1 recurrence (5.56%) was found. The single recurrence was observed nasally in the right eye (first site operated) of a female patient 55 months after the second PECA procedure. None of the operated eyes lost any lines of corrected distance visual acuity, and 22% gained at least 1 line of corrected distance visual acuity.
  
  
  CONCLUSIONS
  In this series, harvesting the conjunctival autograft from the same site several months later does not appear to increase the rate of recurrence. Sequential PECA is a safe and effective method of addressing double-headed pterygia.
