LKC Technologies RETeval®
Overview
The RETeval® is a revolutionary handheld electroretinography (ERG) and visual evoked potential (VEP) device designed to detect, predict, and monitor retinal and optic nerve diseases. Portable and non-invasive, it uses advanced full-field ganzfeld functionality with patented sensor strip electrodes (no corneal contact required) and real-time pupillography that adjusts for pupil size — making it suitable for patients of any age, without mydriasis or sedation. With over 200 peer-reviewed publications and inclusion in AAO Preferred Practice Patterns for diabetic retinopathy, RETeval provides objective functional data that anticipates structural damage.
