Many diseases and disorders affect various cell populations in the retina, and ERGs provide an objective, non-invasive method of evaluating retinal function.
RETeval is the only FDA 510(k) cleared, non-mydriatic, full-field mobile ERG device, and is easier to use than you might think.
Test almost anyone, almost anywhere, quickly and easily, with interpretation aided by a 500+ subject, age-matched normative database.
The First and Only FDA Cleared, Non-Mydriatic, Hand-Held, Full-Field ERG Device
Portable, powerful ERG testing in the palm of your hand. Easily integrates into your current workflow.
RETeval 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.
New to Visual Electrophysiology or Thinking About a Change?
Have you have been considering adding electrodiagnostics to your practice but thought it was too complex or out of reach due to space limitations, cost or staffing, or are you dissatisfied with your current device? RETeval is an affordable, practical and robust solution that helps bridge the gap between structure and function that easily integrates into your current practice flow.
Objectively assess diabetic retinopathy1,2, glaucoma3,7, CRVO4, acquired and inherited retinal diseases5,6, pediatric nystagmus8. Additionally, changes in color vision measured by extended color vision diagnostics such as the new ColorDx® CCT-HD, may suggest that additional assessment of retinal function with an ERG device might be an appropriate next step.
