title: Epidemiologic characteristics of retinal detachment surgery at a specialized unit in Denmark.
abstract: OBJECTIVE
  To examine the incidence of retinal detachments and to evaluate patient profiles and surgical characteristics.
  
  
  METHODS
  Retrospective review of patients operated for primary retinal detachment (RD) and redetachment between 2010 and 2012 at the Department of Ophthalmology, Odense University Hospital, Denmark. We included all RD such as rhegmatogenous retinal detachment (RRD), tractional retinal detachment (TRD) and exudative retinal detachment (ERD).
  
  
  RESULTS
  In total, 779 RD surgeries were performed: 83.7% (n = 652) primary operations and 16.3% (n = 127) reoperation. For primary operation, pars plana vitrectomy (PPV), scleral buckling and combined operations were performed in 95.1% (n = 620), 4.6% (n = 30) and 0.3% (n = 2) respectively. Over time there was less use of silicone oil and greater use of gas tamponade (p = <0.001), less simultaneous cataract operations (p = <0.001), less use of cryotherapy (p = 0.045) and more use of peeling procedures (p = <0.001) in primary operations. The annual incidence of surgery for primary RD was 22.0 [95% confidence interval (CI) 20.4-23.8] per 100 000 inhabitants aged >15 years. Retinal detachment (RD) was more common in males than females (1.8:1), and mean age at presentation was 61.8 years (standard deviations ± 12.3). The annual incidence for RRD and TRD operation was 20.72 (95% CI 19.11-22.43) and 1.25 (95% CI 0.9-1.7) per 100 000 inhabitants >15 years.
  
  
  CONCLUSIONS
  This study presents the first overall incidence for RD in Denmark. The highest incidence of RRD was among males aged 60 to 79 years, whereas TRD was among females at same age. Pars plana vitrectomy (PPV) was the preferred surgical technique, and during 2012 all RD patients were treated with PPV, independent of lens status and age.
