title: Current popularity of pneumatic retinopexy.
abstract: OBJECTIVE
  To compare the popularity of pneumatic retinopexy (PR) in 1997 with its popularity in 1990 among retinal specialists.
  
  
  METHODS
  In 1997, a survey was mailed to the 1994-1995 members of the Retina or Vitreous Societies who lived in the United States or Canada, asking how they would manage a hypothetical retinal detachment. The choices were limited to PR, segmental scleral buckling, scleral bucking with encircling, primary vitrectomy, and Lincoff balloon. The results of the survey were compared with those previously reported by a similar survey in 1990.
  
  
  RESULTS
  The majority (55%) of respondents selected PR, which is a twofold increase over those who preferred it in 1990 (odds ratio 2.08; 95% confidence interval 1.53, 2.85). The popularity of PR was inversely proportional to the length of time the respondents had been in practice. If the eye with the hypothetical detachment had pseudophakia, only 30% of respondents selected PR. If the eye had additional tears, vitreous hemorrhage, or lattice degeneration, only about one-sixth preferred PR.
  
  
  CONCLUSIONS
  Pneumatic retinopexy was much more popular in 1997 than it was in 1990. Its popularity continues to be influenced by the age of the surgeon and by the complexity of the detachment.
