Inexpensive. Time efficient. Portable. Valid indicator of gaze stability and vision acuity. Applicable to subjects aged 3–85. Relevance – Significant percentage of children and adults have vestibular deficits. – >150 million American have a visual impairment.

Tested adults and children with 3 optotype sets. Validated cDVA with bithermal calorics, rotational chair, and light box testing.
