Bertec Vision Advantage In Use

Bertec Vision Advantage

The Bertec Vision Advantage (BVA) identifies dysfunction in the vestibular ocular reflex (VOR) per the Dynamic Visual Acuity Test. The BVA provides a more objective test than the standard clinical DVA test using an eye chart. The BVA also includes a Gaze Stability Test that identifies when the VOR falls below normal limits and whether there is an asymmetry between the left and right side. These advanced capabilities allow the clinician to customize treatment to the patient, resulting in optimal patient outcomes.

  • Wireless and light weight head tracker
  • Next generation VOR assessments
  • Patient-specific baseline comparison
  • Automatic sensor calibration
  • New technology allows for unrestricted patient movements and more flexibility for clinicians
  • Optimal patient outcomes



Do your patients have the optimal eye and head coordination to maximize their performance? Find out using the Bertec Vision Advantage system, which identifies dysfunction in the vestibular ocular reflex (VOR) per the Dynamic Visual Acuity (DVA) Test and measures the head velocity, axis, and direction where visual accuracy breaks down per the Gaze Stabilization Test (GST).

The Bertec Vision Advantage’s portable design allows your facility to use the system in multiple locations to improve patient workflow.
