Sensitivity and Specificity of Short Duration Transient Visual Evoked Potentials (SD-tVEP) in Discriminating Normal from Glaucomatous Eyes
Investigative Ophthalmology & Visual Science , 2013
Conclusion: Short-duration transient VEP (Diopsys NOVA-LX) objectively identified decreased visual function and discriminated between healthy and glaucomatous eyes and showed good differentiation between healthy eyes and those with early visual field loss. Read full study.

Progressive Loss of Retinal Ganglion Cell Function Precedes Structural Loss by Several Years in Glaucoma Suspects
Investigative Ophthalmology & Visual Science, 2013
Conclusion: In patients who are glaucoma suspects, PERG signal anticipates an equivalent loss of OCT signal by several years. Read full study.

Effect of different stimulus configurations on the visual evoked potential (VEP)
Documenta Ophthalmologica, 2012
Conclusion: The finding of VEP response linearity for the circular stimulus fields, and repeatability for all stimulus configurations, suggests that the clinician may be able to use the VEP technique with the suggested test patterns as a rapid and simple tool for objective assessment for several types of visual-field defects for a range of abnormal visual conditions and special populations. Read full study.

Short Duration Transient Visual Evoked Potentials in Glaucomatous Eyes
Journal of Glaucoma, 2011
Conclusion: In cases of asymmetric glaucoma, SD-tVEP results correlate significantly with the level of VF damage as measured by MD. In the eyes with more advanced VF loss, reduced SD-tVEP amplitude was associated with decreased macular thickness on OCT. These findings suggest that SD-tVEP may be a fast and objective method to assess or screen for functional damage in glaucomatous eyes. Read full study.

Short-duration transient visual evoked potential for objective measurement of refractive errors
Documenta Ophthalmologica, 2011
Conclusion: The VEP scoring system has a potential for objective screening of RE and for a more accurate 3-step objective refraction. Read full study.

Repeatability of short-duration transient visual evoked potentials in normal subjects
Documenta Ophthalmologica, 2010
Conclusion: Short-duration transient VEP technology showed good within-session, inter-session repeatability, and good inter-eye correlation and agreement. Read full study.

ISCEV standard for clinical visual evoked potentials (2009 update)
Documenta Ophthalmologica, 2010
Visual evoked potentials (VEPs) can provide important diagnostic information regarding the functional integrity of the visual system. This document updates the ISCEV standard for clinical VEP testing and supersedes the 2004 standard.Read full study.

The Visual Evoked Potential in Glaucoma and Ocular Hypertension
Investigative Ophthalmology & Visual Science, 1983
Conclusion: The finding that is of clinical importance is the presence of abnormally long VEP latencies in some patients with ocular hypertension. The abnormal prolongation of VEP latency in these eyes may reflect subclinical optic nerve lesions that have not been uncovered with other techniques. Read full study.

Pediatric Papers
Retinoblastoma Detected by Preschool Vision Screening Using Visual-Evoked Potentials
Journal of Pediatric Ophthalmology & Strabismus, 2013
Abstract: Two cases of otherwise healthy children with no known family history of retinoblastoma who were diagnosed as having retinoblastoma after failing a visual-evoked potential test during a well-child visit are reported. This early detection allowed for eye-sparing treatment.Read full Case Report.

A New Visual Evoked Potential System for Visual Screening in Infants and Young Children
Journal of AAPOS, 2004
Conclusion: With its easy electrode placement and rapid, attractive stimulus, the new system (Enfant) overcomes technical difficulties which were associated with older VEP techniques.Read full study.

Predicting Potential Acuities in Amblyopes
Documenta Ophthalmologica, 2007
Conclusion: The results indicate that pre-amblyopic therapy SVEP acuity can be a good predictor of post-amblyopic therapy Snellen acuity. Read full study.

Evaluation of Pre-Perimetric Glaucoma Patients using Short Duration Transient Visual Evoked Potentials (2013)
Conclusion: The SD-tVEP low contrast latency parameter was able to differentiate normal and PrG patients and may be useful for the diagnosis of glaucoma with structural abnormalities but normal achromatic perimetry. View full poster.

Optimization of the Pattern Visual Evoked Potential (VEP) in the Visually-Normal and Mild Traumatic Brain Injury (mTBI) Populations (2013)
Conclusion: The use of the 20 min arc check size at both contrast levels represents an optimal clinical VEP test protocol in both the visually-normal and mTBI groups; thus, a common stimulus combination produced the largest VEP amplitude, in conjunction with normal latency values.View full poster.

Quantifying the Impact of Vision Training using SD Transient Visual Evoked Potential (2013)
Conclusion: SD-tVEP objectively measured the reduction in the P100 latency as a result of the vision training program. The low contrast SD-tVEP P100 latency demonstrated the largest sensitivity to the training. View full poster.

Optimization of Check Size and Contrast on the Visual-Evoked Potential (VEP) in Visually-Normal Individuals (2013)
Conclusion:Useful for amplitude-sensitive conditions, such as amblyopia and macular degeneration, and latency-sensitive conditions such as glaucoma and multiple sclerosis.View full poster.

Effect of Simulated Octant Visual Field Defects on the Visual-Evoked Potential (VEP) (2013)
Conclusion:The results provided evidence that the VEP, an objective technique, could be used reliably to detect relatively small simulated scotomas in each subject. The VEP can now be extended even further and be used as a relatively rapid and simple objective technique to assess small visual-field defects. View full poster.

Effect of Test Duration on the Visual-Evoked Potential (VEP) and Alpha Wave Responses (2013)
Conclusion:The VEP and alpha wave are both physiological phenomenon pertinent to clinical practice. Furthermore, regardless of the VEP test duration used, the stability of alpha variation across test durations provides a window into the subject’s attentional state. View full poster.

Effect of Ocular Vision Rehabilitation (OVR) on Visual Evoked Potential (VEP) Responses and Visual Attention in Mild Traumatic Brain Injury (mTBI) (2013)
Conclusion:The results demonstrate that the VEP could be used to assess objectively the effect of OVR in mTBI. View full poster.

Sensitivity and Specificity of SD-tVEP in Discriminating Normal from Glaucomatous Eyes (2012)
