title: Complete occlusion of the anterior capsular opening by fibrocellular membrane associated with retained silicone oil: a clinicopathologic correlation.
abstract: BACKGROUND
  To report the clinicopathologic features of a fibrocellular membrane in a pseudophakic eye with retained silicone oil in the absence of any capsular contraction syndrome, necessitating repeat anterior capsulorhexis.
  
  
  METHODS
  Clinicopathologic report of a case.
  
  
  RESULTS
  Histopathologic study of the membrane showed absence of any true periodic acid Schiff-positive capsule within the specimen. Clinically, there was no evidence of any anterior capsular contraction. The fibrocellular membrane may have occurred as a result of inflammatory and mechanical effects of silicone oil in the anterior chamber or as a result of the intraocular lens design.
  
  
  CONCLUSIONS
  The authors report the clinicopathologic features of a fibrocellular membrane occluding the anterior capsular opening in a pseudophakic eye with retained silicone oil, in the absence of any capsular contraction. The stimulus for its formation may have been the inflammatory and mechanical effects of retained silicone oil in the anterior chamber.
