title: Restrictive strabismus following Jones tube insertion: a case series of 8 patients.
abstract: BACKGROUND
  Restrictive strabismus and diplopia are an uncommon complication of conjunctivodacryocystorhinostomy, with insertion of the Lester-Jones tube. A literature review revealed only 4 published reports of this complication with a total of 4 patients affected.
  
  
  METHODS
  We report on a series of 8 patients who presented with restrictive strabismus and diplopia following Jones tube insertion.
  
  
  RESULTS
  Time to presentation was variable and was found to occur from several months to as long as 6 years after insertion. Treatment included topical steroid therapy initially. Surgery was done to release adhesions and scarring if topical treatment failed. Mitomycin C was used in 2 patients. Only 4 of the 8 patients had successful resolution of their diplopia with either therapy.
  
  
  CONCLUSIONS
  Diplopia following Jones tube insertion is an infrequent complication of surgery. Medical or surgical therapy can be help resolve symptoms but is often unsuccessful.
