title: Recurrent retinal detachment: does initial treatment matter?
abstract: OBJECTIVE
  To evaluate the treatment course of patients with primary rhegmatogenous retinal detachment (RRD) that re-detach after initial retinal detachment surgery.
  
  
  METHODS
  Patients were divided into three groups based on initial surgical treatment: scleral buckle procedure (SBP) (63 eyes), pars plana vitrectomy (PPV) (88 eyes) and combined SBP/PPV (135 eyes). Charts were reviewed for a mean follow-up of 12 months.
  
  
  RESULTS
  Average number of secondary procedures to achieve anatomical success was lowest in the SBP group (1.1), compared with the PPV group (1.47) and the SBP/PPV group (1.5) (p<0.05). Patients that re-detached after initial PPV/SBP, PPV or SBP required silicone oil injection in 83%, 60% and 22% of the cases and had final best-corrected visual acuity better than or equal to 20/50 in 21%, 33% and 45% of the cases, respectively. Phakic patients that re-detached after initial treatment with PPV/SBP, PPV and SBP required pars plana lensectomy (PPL) in 42%, 25% and 12.5% of the cases, respectively.
  
  
  CONCLUSIONS
  Patients with primary RRD that re-detach after initial treatment with SBP require fewer number of secondary operations and silicone oil injections, show a trend for better visual outcomes and are less likely to develop dense cataract or to require PPL compared to patients that re-detach after initial PPV or PPV/SBP.
