title: Heavy silicone oil tamponade after failed macular hole surgery with perfluoropropane (C3F8): a report of five cases.
abstract: We report five cases of persistent macular holes following conventional surgery. Subsequent management included pars plana vitrectomy, extended Trypan Blue-assisted ILM peel and heavy silicone oil (HSO) tamponade with supine posture.
  
  
  OBJECTIVE
  To report results of redo macular hole surgery using heavy silicone oil (HSO) tamponade.
  
  
  METHODS
  Retrospective study of patients with primary failure of macular hole surgery, who failed to posture prone due to medical reasons. Further surgery consisted of vitrectomy, extended-dye-assisted ILM peel, and HSO tamponade with supine posture.
  
  
  RESULTS
  Anatomical closure of macular holes was achieved in three out of five cases with parallel improvement in visual acuity after 3 months of removal of heavy silicone oil. These were confirmed clinically and by ocular coherence tomography (OCT).
  
  
  CONCLUSIONS
  HSO may be used as tamponade in patients with unsuccessful primary macular-hole surgery, negating the need of prone posturing post-operatively.
