title: Excision of pterygium and conjunctival autograft.
abstract: BACKGROUND
  Pterygium is a common disease in Israel. Different surgical techniques are used to manage it with varying degrees of success.
  
  
  OBJECTIVE
  To evaluate the efficacy and safety of a conjunctival autograft after excision of pterygium.
  
  
  METHODS
  Excision followed by conjunctival autograft was used to treat 40 eyes of 40 patients with pterygium. The surgical results were evaluated retrospectively. Follow-up continued for a median of 296 days (range 6-1,056); 26 cases were followed for more than 100 days (average 418 days) and comprised the study cohort. All reported procedures were performed consequentially and by one surgeon in the Tel Aviv Sourasky Medical Center, Israel between 1 June 1997 and 31 March 2000.
  
  
  RESULTS
  There were two recurrences of pterygium (2/26, 7.7%) 2 months postoperatively. There were no major complications. Superficial comeal vessels (without concurrent fibrosis) appeared in 10 of 17 cases sutured with nylon, but none occurred in any of the seven grafts sutured with vicryl (P = 0.068). The average LogMAR-corrected visual acuity of the study group improved slightly, from 6/16.5 to 6/11 (P = 0.003).
  
  
  CONCLUSIONS
  Excision of pterygium with a conjunctival autograft is a safe and effective operation, with no procedure-specific added surgical risks. The relatively long surgical time and microsurgical methods required to perform the procedure properly have hindered its acceptance as the mainstream approach to pterygium management. Long-term follow-up is needed for better discernment of the surgical results in Israel.
