title: [Pterygium and lipid peroxidation].
abstract: OBJECTIVE
  The mechanism of light damage causing pterygium was investigated from the point of view of lipid peroxidation.
  
  
  METHODS
  22 patients with pterygium underwent excision of pterygium and a little superior bulbar conjunctiva was excised as normal control. The lipid peroxidation reaction of both pathologic and normal samples was analyzed by measuring the concentration of malondialdehyde.
  
  
  RESULTS
  The concentration of malondialdehyde in the pathologic samples was much higher than that in the normal samples (P < 0.01).
  
  
  CONCLUSIONS
  Light Induced peroxidation reaction is closely related to the pterygium formation.
