Description
  • Initial diagnosis (Preclinical) of retinal changes
  • Set of specially designed electrodes.
  • Mini Ganzfeld Stimulator

 Tests Electrophysiological vision is aimed at the objective evaluation of the visual pathway from the retina to the cortex:

  •  Electroretinography (ERG) – activity log electrical of the retina (electroretinogram) generated in response to the light stimulus.
  • Visual evoked potentials (VEP) – study of electrophysiological signals extracted from electroencephalographic activity in the visual cortex recorded from the superimposed scalp.
  • Electro-oculography (EOG) – record of changes in electrical potential through the retinal pigment epithelium recorded during successive periods of light and dark adaptations .
