Por que realizar testes de ERG ou PEV?
As soluções de teste de ERG (eletrorretinografia) e teste de PEV (potencial evocado visual) desempenham um papel fundamental na obtenção de informações de diagnóstico em humanos e animais, auxiliando clínicos e pesquisadores com dados abrangentes sobre o funcionamento da retina e das vias visuais.
DIAGNÓSTICO
O teste ERG/PEV eficiente e eficaz oferece uma ajuda objetiva na detecção e confirmação da presença de doenças oculares hereditárias ou adquiridas.
MONITORAR
Acompanhe a progressão da doença e/ou preveja as necessidades e os resultados do tratamento.
PESQUISA
Amplie sua compreensão da função da retina e avalie os fatores que afetam os processos da retina e as vias visuais com resultados precisos e repetíveis.

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.
See why clinicians are calling this a pivotal moment in eye care history >
“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.”
Practical Implementation of ERG into a Comprehensive Practice

RETeval: Core Cases from the Clinical Compendium
With the incorporation of a single simple test, these eyecare providers are elevating their patient care through easier management decisions and better patient education.
With each of the 4 cases presented in this eBook, learn:
-
- Why was an ERG performed?
- Quais foram as descobertas do ERG?
- How did the ERG impact next steps?
“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.”
Sobre a 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.
