title: Primary rhegmatogenous retinal detachment - surgical methods and anatomical outcome.
abstract: OBJECTIVE
  The aim of the study was to evaluate the anatomical success of surgical management of primary rhegmatogenous retinal detachment (RRD) and to compare the anatomical outcomes from different surgical techniques.
  
  
  METHODS
  During 2012, 517 consecutive eyes (514 patients) were operated by 11 surgeons at the Department of Ophthalmology, Oslo University Hospital. Patient records were retrospectively analysed with no exclusions. Main outcome measures were primary and final anatomical success. Primary anatomical success was defined as retinal reattachment 6 months after primary surgery with reoperations excluded. Final anatomical success was defined as retinal reattachment 6 months after primary surgery with reoperations included.
  
  
  RESULTS
  Incidence of RRD was 18.6 eyes per 100 000 person-years. The macula was detached in 50.5% of the eyes at baseline. Of 517 operated eyes, 317 (61.3%) underwent pars plana vitrectomy (PPV), 23 (4.5%) pars plana vitrectomy together with a scleral buckle (PPV-SB), 175 (33.9%) scleral buckle (SB) surgery and two (0.4%) pneumatic retinopexy (PR). Primary anatomical success was 89.0% in the PPV group, 87.0% in the PPV-SB group and 85.7% in the SB group. Final anatomical success was 98.1% in the PPV group, 100% in the PPV-SB group and 99.4% in the SB group. Factors which were correlated to the redetachment were detachment of more than 6 clock hours (p = 0.003) and visual acuity (VA) on Snellen chart <0.5 (p = 0.02) at baseline.
  
  
  CONCLUSIONS
  This study showed no significant differences in the surgical success rates in the treatment of RRD between pars plana vitrectomy, scleral buckle or the combined procedure of vitrectomy and buckle. Factors which were found to be correlated to the redetachment of the retina were large detachment and low VA.
