title: [The investigation of FFA fixative solution for retina].
abstract: OBJECTIVE
  To search for an effective fixative solution for retina.
  
  
  METHODS
  One group of retinas were fixed in an admixture of formalin, dehydrated alcohol and glacial acetic acid (FFA). The other group of retinas were fixed in 10% neutral formalin.HE and immunohistochemistry were performed. Then compare the difference under the light microscope.
  
  
  RESULTS
  The structure of the retinas fixed in FFA fixative solution was clear. The cells were arranged and compacted. Few exfoliation of the tissue from the glass slide was observed.
  
  
  CONCLUSIONS
  FFA fixative solution is superior to 10% neutral formalin for the fixation of retina.
