LKC RETeval Hand-held ERG & VP System

LKC RETeval Hand-held ERG & VP System

Point‑of‑Care Electrodiagnostics for Every Age and Setting

The RETeval® is the world’s first completely portable device that performs full‑field electroretinography (ERG) and flash visual evoked potentials (VEP) without the need for corneal electrodes, mydriatic drops, or a dark room. Using patented sensor‑strip skin electrodes and built‑in constant‑luminance Ganzfeld stimulation, the unit delivers ISCEV‑compliant results in minutes—anywhere from primary‑care clinics to operating theatres.

Key Features
  • All‑in‑One ERG & VEP: Performs photopic flicker, scotopic and photopic flash ERG, diabetic‑retinopathy (DR) function testing, and flash VEP through the same hand‑held console.
  • Non‑Mydriatic, Skin‑Electrode Convenience: Disposable sensor strips adhere beneath the lower lid—no topical anaesthetic or contact electrodes required and no corneal abrasion risk.
  • Automatic Pupil‑Scaled Stimulus: Infra‑red pupillography measures pupil size in real time and adjusts flash strength so retinal illuminance remains constant, even without dilation.
  • Colour‑Coded, Normative Reports: Built‑in age‑matched database instantly flags amplitude or implicit‑time deviations, simplifying interpretation for non‑specialists.
  • Truly Portable & Battery Powered: Weighs 8.5 oz (240 g) and runs all day on its rechargeable battery; a pocket‑sized docking station recharges and stores the unit when not in use.
  • Rapid, Reimbursable Workflow: Typical bilateral DR‑ERG takes under three minutes and qualifies for CPT 92275 (ERG) or 95930 (VEP).
  • Data Security & Connectivity: Store thousands of tests on the device, export PDFs via USB, or send results directly to your EMR with the companion PC software.
