title: Practice preferences for glaucoma surgery: a survey of the american glaucoma society in 2008.
abstract: OBJECTIVE
  To evaluate glaucoma surgical practice patterns among members of the American Glaucoma Society (AGS).
  
  
  METHODS
  An anonymous web-based survey was sent to AGS members to determine their preferred surgical approach in ten clinical settings. Survey results were compared with those from 1996 and 2002.
  
  
  RESULTS
  A total of 125 (22%) AGS members responded to the survey. Mean glaucoma drainage device (GDD) usage increased from 17.5% (range: 5% to 37%; standard deviation [SD]: 10.9%) in 1996 to 50.8% (range: 15% to 76%; SD: 17.3%) in 2008, and mean trabeculectomy usage decreased from 80.8% (range: 62% to 93%; SD: 11.3%) in 1996 to 45.5% (range: 16% to 80%; SD: 17.9) in 2008. GDD was most popular in none of 8 clinical settings in 1996, and 5 of 8 clinical settings in 2008. Mitomycin C was selected as an adjunctive antifibrotic agent to trabeculectomy in 85% to 99% of cases.
  
  
  CONCLUSIONS
  Glaucoma surgical practice patterns have changed since 1996. The use of a GDD has progressively increased, and the popularity of trabeculectomy decreased between 1996 and 2008. Mitomycin C remains the most frequently selected antifibrotic agent used as an adjunct to trabeculectomy.From Boston Medical Center (MAD), Boston University School of Medicine, Boston, Massachusetts; Bascom Palmer Eye Institute (SJG, WJF, WS, RKP), University of Miami, Miller School of Medicine, Miami, Florida; and the Department of Ophthalmology (PPC), University of Washington, Seattle, Washington.The authors have no financial or proprietary interest in the materials presented herein.Address correspondence to Steven J.
