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.
DIAGNOSE
Efficient and effective ERG / VEP testing provides an objective aid in detecting and confirming the presence of inherited or acquired eye disease.
MONITOR
Track disease progression and/or predict treatment needs and outcomes.
RESEARCH
Expand your understanding of retinal function and assess the factors impacting retinal processes and visual pathways with accurate and repeatable results.
Our ERG/VEP Devices
RETeval®
The only FDA-cleared, portable, battery-powered, non-mydriatic ERG/VEP Testing Device. ISCEV-compliant. Remarkably straightforward to use.
RETevet™
For both veterinary ophthalmologists and researchers, measure an animal’s retinal function with a view of the eye in real-time.
UTAS™ mf/PERG
Conduct multifocal and pattern ERG/VEP tests with an intuitive interface and small, manageable footprint.
Need supplies?
“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.”
Webinars
These webinars offer tips and comprehensive information on why electrophysiology and LKC’s systems and devices are the perfect solution for you.
Objective functional testing for glaucoma? Yes!
“When do I refer out?” Best management practices for diabetic retinopathy
Meaningful Clinical Endpoints with ERG
“RETeval really has made me a better diagnostician. It has allowed me to get early information about a patient’s eye health before disease becomes clinically visible.”
About LKC
For 45+ years, LKC Technologies has been making functional eye testing simple and practical for busy clinicians. The handheld, portable RETeval ERG/VEP device aids in the diagnosis and management of ischemic conditions such as diabetic retinopathy, optic nerve conditions, and other retinal dystrophies by providing objective results without corneal contact.
