title: Outcomes of pseudophakic retinal detachment.
abstract: OBJECTIVE
  To provide data on the outcome of pseudophakic retinal detachment (PRD).
  
  
  METHODS
  In a retrospective case-control study, we identified a consecutive series of 63 298 cataract extractions (45 520 patients) performed in a single institution between 1994 and 2003. We included 249 cases with PRD and 845 controls that had cataract surgery on the same day as cases but without PRD. Outcome measures were the risk of impaired vision (6/18-6/60) or blindness (<6/60). A multinomial logistic regression model evaluated risk factors for impaired vision or blindness, while multivariable regression models measured the relative risk of poor visual outcome for posterior capsule tear (PCT) and PRD.
  
  
  RESULTS
  Primary pars plana vitrectomy was performed on 207 (84.5%) of the 245 cases treated with surgery, of which 175 (71.4%) needed one procedure. The final acuity was <6/60 in 62 cases (24.9%) and 34 controls (4.0%). After PRD, the relative risk for a final visual outcome <6/60 was 6.8 [95% confidence interval (CI) 4.3-10.6; p < 0.001], and we estimated that the proportion of blindness attributable to PRD was 1.1% (CI 0.7-1.9%). A PCT prior to a PRD was not associated with an increased risk of macular detachment (p = 0.165), but it did carry an increased risk of blindness [odds ratio 4.8 (CI 2.2-10.2; p < 0.001].
  
  
  CONCLUSIONS
  Although a PCT has an adverse effect on visual outcome after cataract surgery, a PRD is the foremost surgery-related risk for a poor visual outcome. Patient education of symptoms and prompt treatment may limit the visual consequences.
