RETeval®

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.
