EOG – ERG – VEP

Electrooculogram – EOG

Measures the resting potential of the eye and assesses the function of the retinal pigment epithelium under the retina. It is used for the diagnosis and follow-up of inherited retinal diseases.

Electroretinogram – ERG

Records the electrical response of the retina and provides information about its function when different light patterns are flashed into the eye. It is mainly used for the diagnosis and follow-up of inherited retinal and choroïdal diseases.

Visual Evoqued Potential – VEP

Detects and measures the response evoked in the visual cortex due to a change in visual stimulus. It reflects the activity of the whole visual pathway from the retina to the visual cortex and is used to help determine level of visual acuity.
