Objective Measurement of Entire Visual Pathway.
It’s not just our eyes that “see” so when evaluating visual function, it helps to get information on the entire visual pathway. Diopsys® VEP (visual evoked potential) vision testing gives you the ability to obtain objective information on the function of the whole vision system, from the anterior segment of the eye to the visual cortex.
Other common functional tests that evaluate the visual pathway are often unreliable due to the subjective nature of the test and the required patient participation.1 Diopsys® VEP tests offer you more confidence in results, as there is no “button pushing” or verbal response needed.
Visual Evoked Potential Vision Testing (VEP)
Since VEP testing provides important diagnostic information regarding the functional integrity of the entire visual system, it has been found to be useful for the detection and monitoring of many types of visual abnormalities.2 It is often used to help doctors diagnose and manage neuro-visual disorders such as optic neuritis, amblyopia, and vision problems due to TBI.3 4 5

The VEP results correlated significantly with the severity of visual field damage, but the results were obtained objectively, which helps give eye care specialists more confidence in the findings.
