title: [Color Doppler ultrasonography of the orbit in the treatment and evolution of the open angle glaucoma with normalized pressure].
abstract: The purpose of the paper consists to evaluate the vascular component that it takes part to ethiopatogenie of certain forms of primary open angle glaucomas, as well as to suggest a specific treatment.
  
  
  METHODS
  14 patients (28 eyes) with primary open angle glaucomas with average of 64 years were investigated by Color Doppler Imaging. All patients present deteriorations papilo-perimetric or/and visual acuity, in spite of normalized pressure by medical or surgical treatment.
  
  
  RESULTS
  The calculus of the velocimetric indices allowed us to measure the vascular resistance index that is increased at 6 patients in ophthalmic circulation, 4 patients in central retinal artery and 2 patients in whole shaft carotid-ophthalmic. We are found a correlation between papilo-perimetric deteriorations and the value of the vascular resistance index, too. Giving vasodilatative drugs that grow the ocular blood flow by improving the microcirculation at the level of the optic nerve's head, such as calcium channel blockers, could benefit effects for this type of patients.
  
  
  CONCLUSIONS
  Orbitar Color Doppler Imaging allows to evaluate the vascular lesions that have a negative influence in the evolution of primary open angle glaucomas, and, therefore, suggesting a specific treatment.
