title: [The physical and chemical changes in the eye structure after sulfurhexafluoride injection into the rabbit vitreous].
abstract: OBJECTIVE
  The aim of our paper was to observe the physical and chemical changes in the aqueous humor, lens, gelatous and fluid part of the vitreous body after the sulfurhexafluoride injection into the vitreous body.
  
  
  METHODS
  The New Zealand rabbits were randomized into the control and experimental group which were injected the gas into the vitreous body. The interesting samples were investigated during the 2nd, 7th and 14th day of the experiment. We estimated the volume of the fluid part of the vitreous body, its electrical resistance, the whole protein concentration (in the aqueous humor, lens and vitreous), and electrolite concentration (in the aqueous humor and fluid part of the vitreous body).
  
  
  RESULTS
  We observed the increase of the fluid fraction in the vitreous body with the increasing of the whole protein concentration, changes in the K+ concentration and decrease of the electrical resistance in the vitreous fluid fraction.
  
  
  CONCLUSIONS
  On the basis of our experimental results we can assume that expanding sulfurhexafluoride gas could mechanically disrupt the vitreous structure. Moreover, the rapid intrabulbar pressure increase after the injection can cause the cilliary body ischaemia and the eye barrier collapse.
