title: [Contribution of the study of evolution of major electrolytes contents in the aqueous humour by X-ray fluorescence and ICP/AES].
abstract: BACKGROUND
  In the scope of this study, we had to do a qualitative and quantitative research of the current electrolytes as part of aqueous humour samples taken from patients suffering from cataract.
  
  
  METHODS
  The tests were carried out by X-ray fluorescence and ICP/AES. The detection limit for the electrolytes varied from 0.005 to 0.1 ppm.
  
  
  RESULTS
  The test results show iron (minimum 0.82ppm; maximum 25.50ppm), copper (0.28ppm; 8.17ppm), brome (5.18 ppm ; 55.82ppm), zinc (0.70ppm ; 9.78ppm ), sodium (1274.83ppm, 5211.67 ppm), potassium (55.52ppm ; 255.02ppm), calcium (26.46 ppm ; 256.81ppm), magnesium (5.77ppm; 70.33ppm).
  
  
  CONCLUSIONS
  The data study have enabled us to establish reference value for each electrolyte. Study of the comparative reference values, together with the contents found in the normal aqueous humour, the normal and pathologic crystalline lens, has shown a noticeably low concentration of electrolytes and breakdown of the sodium/potassium pump which ensures ionic exchange between aqueous humour and the crystalline lens.
