Assessment of Human Visual Acuity Using Visual Evoked Potential: A Review

Sensors, 2020
Visual evoked potential (VEP) has been used as an alternative method to assess visual acuity objectively, especially in non-verbal infants and adults with low intellectual abilities or malingering.

Effect of simulated octant visual field defects on the visual evoked potential (VEP)

Journal of Optometry, 2014
Several previous clinical research studies1–6 have found the pattern visual-evoked potential (VEP) to be useful in detecting a wide range of visual-field defects objectively. In a previous study completed in our laboratory,6 circular, annular, hemi-field, and quadrant absolute visual-field defects were simulated and assessed objectively for detection ...

Assessing the Effect of Opium Dependence on Visual Evoked Potential (VEP) in Men [PDF]

Addiction and Health, 2010
Background: Opium-dependence having different effects on the nervous system is a common problem, especially in the Middle East and Iran. The aim of this study is evaluating the effects of opium-dependence on visual evoked potential (VEP) in men ...

Development of the spatio-chromatic visual evoked potential (VEP): a longitudinal study

Vision Research, 1998
Most prior visual evoked potential (VEP) research on the development of color vision has employed pattern-reversing stimuli that are not optimal for producing chromatic responses. We measured infant VEPs using low spatial frequency, onset-offset stimuli, modulated along the three axes of a cone-based color space (Derrington et al. [J. Physiol 1984;357,
