title: [Advantage of using echography for optic nerve head estimation of glaucoma patients].
abstract: OBJECTIVE
  To evaluate the possibility and advantages of using echography for optic nerve head estimation of glaucoma patients.
  
  
  METHODS
  146 patients (146 eyes) - group A and 20 glaucoma patients (24 eyes)- group B underwent ultrasound investigation. On B - scan the optic nerve head was evaluated with the help of 10 MHz probe. In the patients with the possibility of glaucoma with transparent ocular media the C/D ratio was measured.
  
  
  RESULTS
  In 6 patients of group A large cup of the optic disc was detected, which correlated with the eye fundus picture. In group B only in one case there was no correlation between echographic image of the optic cup and the eye fundus picture.
  
  
  CONCLUSIONS
  During the ultrasound investigation of the eyes of patients before cataract extraction, corneal transplantation or vitreoretinal surgery we suggest the echography imaging of the optic cup as a routine procedure, which will be helpful in the diagnosis and treatment of glaucoma.
