title: Corneal degeneration following bicanalicular silicone intubation.
abstract: OBJECTIVE
  A case of bilateral arcus-like corneal degeneration in the medial limbal regions following bilateral bicanalicular silicone intubation is reported.
  
  
  METHODS
  Case report.
  
  
  RESULTS
  Bilateral arcus-like corneal opacifications were observed in the medial limbal regions of a 33-year-old woman 3 months after the bilateral silicone intubation with dacryocystorhinostomy. No clinical signs of infection and direct contact of the silicone tubes with those regions of the corneas were observed. Routine laboratory tests revealed no abnormalities, and serum lipoprotein composition was normal.
  
  
  CONCLUSIONS
  Silicone tubing appeared to be the precipitating factor of the corneal opacifications that occurred in this patient.
