title: Primary vitrectomy with Densiron-68 for rhegmatogenous retinal detachment.
abstract: BACKGROUND
  To report a retrospective non-comparative interventional study on the effectiveness and ocular tolerance of a heavy silicone oil tamponade (HSO, Densiron-68) for primary inferior rhegmatogenous retinal detachment (RRD).
  
  
  METHODS
  Forty-one eyes of 41 consecutive patients were recruited between January 2004 and August 2006. Primary vitrectomy with Densiron-68, a heavy silicone oil, was used in all cases. Inclusion criteria were primary RRD with at least one retinal break between 4 and 8 clock hours. The study protocol consisted of a minimum of eight clinic visits: baseline, surgery, 1 week, 1 month and 3 months after the initial surgery; removal of oil and 1 week, 1 month and 3 months postoperatively. The primary endpoint was anatomical re-attachment of the retina. Cases were judged successful when there was reattachment of the retina in the absence of any tamponade agent. The secondary endpoint was to record the visual function and any complications arising from the surgery. Out of 41 patients initially included in the study, 33 completed all follow-up visits.
  
  
  RESULTS
  Anatomical success was achieved in 91% of cases (30 out of 33) with one retinal operation, and rose to 94% (31 out of 33) with additional surgery. Mean visual acuity improved from logMAR 1.19 (SD 0.9) to 0.5 (SD 0.51, p = 0.001). No significant ocular hypertension, clinically significant emulsification of the tamponade or inflammation developed during follow-up.
  
  
  CONCLUSIONS
  With Densiron-68, high anatomical and functional success rates can be achieved with primary vitrectomy for RRD and predominantly inferior pathology.
