Why Run ERG or VEP Tests?

ERG testing (electroretinography) and VEP testing (visual evoked potential) solutions play a vital role in obtaining diagnostic information in both humans and animals, aiding clinicians and researchers with comprehensive data on how the retina and visual pathways are functionally operating.

“We have been very pleased with the RETeval. It has changed the way that we practice and has allowed us to significantly decrease the amount of EUAs with ERGs we perform. Furthermore, it has resulted in earlier diagnosis of patients with inherited retinal degenerations.”
