title: Factors associated with outcomes of pneumatic retinopexy for rhegmatogenous retinal detachments: a retrospective review of 422 cases.
abstract: BACKGROUND
  To determine the factors associated with anatomical and visual outcomes, and complications when using pneumatic retinopexy in the management of rhegmatogenous retinal detachments.
  
  
  METHODS
  On a whole, 406 patients having undergone 422 primary pneumatic retinopexies for the management of rhegmatogenous retinal detachment at a tertiary care hospital, between January 2004 and December 2009, with a minimum follow-up of 3 months were included in this case series. Multivariate logistic regression was used to estimate associations of demographic and clinical factors with anatomical and visual outcomes.
  
  
  RESULTS
  The single operation success rate was 60.7%, and final anatomical success was 99.5%. Male gender and the presence of complications were associated with single operation failure, whereas age over 65 years, poor preoperative visual acuity, the presence of complications were associated with poorer visual outcomes. Better preoperative visual acuity and absence of complications were associated with obtaining both a good visual outcome and anatomical success after a single intervention. The most common complications included new or missed tears (16.3%), delayed subretinal fluid reabsorption (12.1%), and epiretinal membrane (10.2%).
  
  
  CONCLUSIONS
  Several factors are associated with pneumatic retinopexy outcomes for rhegmatogenous retinal detachments. These factors should be taken into consideration when identifying patients who would benefit from pneumatic retinopexy and those who are at risk of requiring additional interventions.
