title: Lactoferrin in tears in contact lens wearers.
abstract: OBJECTIVE
  The purpose of this study was to examine the concentration of lactoferrin in 126 healthy subjects before being fitted with contact lenses. We obtained repeat measurements 9 months following contact lens fitting in patients who developed giant papillary conjunctivitis and in those who were successful contact lens wearers.
  
  
  METHODS
  We accomplished tear stimulation by the use of Allyl sulphide, a non-toxic organic compound. We measured lactoferrin by the radial immuno-diffusion technique.
  
  
  RESULTS
  We found a significant decrease of lactoferrin levels in the tears of patients with giant papillary conjunctivitis.
