It consists of a device (Retimax – CSO) for recording the bio electrical responses evoked during the perception of structured visual stimuli.

The patient who has been connected to skin electrodes is placed in front of a monitor that has black and white squares of variable size and contrast.

Focusing on these structured stimulus, a bio electric signal will be produced in the retina, in the nerve pathways and in the cerebral cortical areas.

The better the fixation, the larger the electrical potential measured by the electrodes. This tool is therefore able to diagnose major diseases, such as: 

  • glaucoma 
  • age-related maculopathies 

Finally, the Retimax allows a visual stimulation to improve the visual acuity of the patient (“visual training”).
