Slideshow Project DOI: /JRRD JSP Aim – Develop vestibular and visual function test that is: Limited in number of participant tests/demands. 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.

Slideshow Project DOI: /JRRD JSP Methods Used computerized test of dynamic visual acuity (cDVA) to measure difference in visual acuity between head still and head moving in yaw. Tested adults and children with 3 optotype sets. Validated cDVA with bithermal calorics, rotational chair, and light box testing.
