title: Presumed occlusion of posterior ciliary arteries following central retinal vein decompression surgery.
abstract: OBJECTIVE
  Sectioning of the posterior scleral ring has been advocated in the treatment of central retinal vein occlusion. We reviewed cases in which this surgery apparently produced sectioning or closure of the short and long posterior ciliary arteries that resulted in a triangular area of choroidal ischemia and permanent chorioretinal lesions.
  
  
  METHODS
  Case series.
  
  
  METHODS
  Clinic-based vitreoretinal referral practice.
  
  
  METHODS
  Four eyes of three patients whose ages ranged from 17 to 53 years underwent sectioning of the posterior scleral rings as treatment for central retinal vein occlusion.
  
  
  METHODS
  Findings from complete ophthalmologic evaluation.
  
  
  RESULTS
  All patients had either an oval or a triangular area of choroidal ischemia nasal to the optic disc and had permanent chorioretinal lesions.
  
  
  CONCLUSIONS
  Valid basis for performing this operation requires further investigation.
