title: Lens-sparing vitrectomy for stage 4 retinopathy of prematurity.
abstract: OBJECTIVE
  To investigate the anatomic results of lens-sparing vitrectomy for tractional stage 4 retinopathy of prematurity (ROP).
  
  
  METHODS
  Retrospective, noncomparative consecutive case series.
  
  
  METHODS
  Thirty-seven eyes (24 patients) with tractional stage 4 ROP.
  
  
  METHODS
  Lens-sparing vitrectomy.
  
  
  METHODS
  Anatomic status of the retina.
  
  
  RESULTS
  Twenty-five eyes had stage 4A ROP, and 12 eyes had stage 4B ROP. With a median follow-up of 13 months (range, 6-27), 32 of 37 eyes (86%) had complete reattachment of the retina. Among eyes with 4A ROP, 21 of 25 eyes (84%) had complete retinal reattachment. Among eyes with 4B ROP, 11 of 12 eyes (92%) had complete retinal reattachment. At last follow-up, 29 of 37 eyes (78%) were able to fix and follow.
  
  
  CONCLUSIONS
  These results indicate that lens-sparing vitrectomy is effective for achieving retinal reattachment in tractional stage 4 ROP. This article contains additional online-only material available at .
