Oftalmología Veterinaria
¿Por qué llevar a cabo las pruebas de ERG o PEV?
Las soluciones de pruebas ERG (Electrorretinografía) y pruebas PEV (Potencial Evocado Visual) desempeñan un papel vital en la obtención de información diagnóstica tanto en humanos como en animales, ayudando a los médicos e investigadores con datos completos sobre cómo funcionan la retina y las vías visuales.
DIAGNÓSTICO
Las pruebas ERG / PEV eficientes y efectivas proporcionan una ayuda objetiva para detectar y confirmar la presencia de enfermedades oculares hereditarias o adquiridas.
MONITORIZAR
Seguimiento de la progresión de la enfermedad o predicción de las necesidades y resultados del tratamiento.
INVESTIGACIÓN
Amplíe su comprensión de la función de la retina y evalúe los factores que afectan los procesos de la retina y las vías visuales con resultados precisos y repetibles.

ERG Named in Preferred Practice Pattern Guidelines for Diabetic Retinopathy
The American Academy of Ophthalmology’s inclusion of ERG demonstrates its valuable role in both diagnosing and managing diabetic retinopathy. This decision reflects the growing recognition that objective, functional testing, alongside structural imaging, is critical for a comprehensive DR assessment.

upcoming webinar
High-Risk, Revealed: ERG in the Exam Lane
Wednesday, April 15th · 8:00 PM Eastern (5:00 PM Pacific)
Have you ever had a patient who surprised you by progressing faster than you expected? Structural testing provides critical insights, but assessing patients’ risk without objective, functional data can feel like reading a map with missing pages. Many eyecare providers are turning to ERG to help fill those gaps. Want to know why?
We invite you to join us for this introductory webinar and peer-to-peer conversation led by Nate Lighthizer, OD, FAAO, and Bradley Grant, OD.
Estamos muy contentos con el RETeval. Ha cambiado la forma de la que actuamos y nos ha permitido disminuir significativamente la cantidad de ERG con anestesia que realizamos. Además, ha resultado en un diagnóstico precoz de pacientes con degeneraciones hereditarias de la retina.
Practical Implementation of ERG into a Comprehensive Practice
Chris Wolfe & EyeCode Education
With this course by Chris Wolfe, OD, FAAO, Dip. ABO, available from Practice Performance Partners, you’ll know exactly when and how to use ERG to improve patient care and protect your practice. We’re giving away coupon codes so you can take the course for FREE!
Webinars
These webinars offer tips and comprehensive information on why electrophysiology and LKC’s systems and devices are the perfect solution for you.
The Blueprint for Functional Assessments
How can ERG predict vision loss in a busy retina practice?
New to Functional Testing? Here are the ABCs of ERG.
How Modern ERG Became Essential for Diabetic Management
First published in Review of Optometry, this cohort of nationally recognized optometrists and educators discuss how modern ERG has evolved from a specialized test to a practical tool that supports everyday management for patients with diabetes.
Two patients can look nearly identical on imaging, yet progress very differently. Modern ERG adds objective functional data to help clarify risk, reduce uncertainty, and guide more precise follow-up and referral decisions. The result is clearer clinical decision-making and more actionable patient conversations.
“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.”
Acerca de LKC
LKC Technologies® is a 35-year veteran of visual electrophysiology (ERG). The RETeval ERG is the only handheld, FDA-cleared device for ERG testing on dilated and un-dilated patients. It was designed to streamline clinic operations and simplify testing for staff and patients alike. It is supported by more than 250 peer-reviewed publications and is used in optometry, ophthalmology, and research settings.
