title: UK national survey of prophylactic YAG iridotomy.
abstract: OBJECTIVE
  Acute angle-closure glaucoma is a common ophthalmic emergency and individuals with shallow anterior chambers and suspected narrow angles are increasingly referred to the hospital eye service for assessment. There appears to be variation in subsequent management, with no national consensus or college guidelines. This study ascertains the current use of prophylactic YAG iridotomy in patients with no known history of an acute angle-closure glaucoma attack, and also the methods used in patient selection.
  
  
  METHODS
  Questionnaire-based survey mailed to 650 UK consultant ophthalmologists with a covering letter in 2003.
  
  
  RESULTS
  A total of 546 questionnaires were returned. In all, 408 respondents (74.7%) confirmed they perform prophylactic YAG iridotomy and of these 347 (85.0%) use patient symptoms and 268 (65.6%) presenting IOP in patient selection, 394 (96.6%) perform gonioscopy and 97 (23.8%) use some form of provocative test first. A total of 135 (25.3%) stated they do not perform this procedure.
  
  
  CONCLUSIONS
  This study reveals current national practice among UK ophthalmologists, with variations in the assessment of patients with narrow angles but a high uptake of prophylactic YAG iridotomy.
