Portable, powerful ERG testing
in the palm of your hand.
RETeval® Hand-Held, Full-Field ERG
Portable, powerful ERG testing in the palm of your hand. Easily integrates into your current practice.
RETeval is the first completely self-contained, hand-held, mobile visual electrophysiology device.
It is efficient and intuitive to administer, requires minimal (if any) changes in workflow, and allows physicians to perform visual electrophysiology testing almost anywhere.
Utilizing a miniature integrated Ganzfeld with multiple flash and flicker protocols, RETeval provides an objective, robust assessment of retinal function.
- A soft eyecup that is comfortable for patients while minimizing interference from external light sources
- High quality, robust materials with excellent shielding from electromagnetic interference
- Dynamic luminance that allows for testing of dilated and un-dilated pupils (based on patient/physician’s needs) while maintaining constant luminance.
New to Visual Electrophysiology?
If you have been considering adding electrodiagnostics to your practice, or thought it was out of reach due to space limitations, cost, or staffing, RETeval is an affordable, practical and robust solution that helps bridge the gap between structure and function that easily integrates into your current practice.
Take RETeval to the patient, almost anywhere.
