Description
The objective of this research is to use the BERTEC Vision Advantage system as a tool to examine the relationship between the Vestibulo-Ocular Reflex (VOR) and balance with and without multifocal lens (i.e., bifocals and progressives) spectacles. Vision is closely associated with balance, and impaired vision is a factor for falls, especially in the elderly. Some studies have linked multifocal lens spectacles to decreased vision while walking and impaired balance. The BERTEC Vision Advantage system measures baseline visual acuity, visual processing time, dynamic visual acuity, and gaze stabilization, all important factors of vision while ambulating. We are currently developing a protocol to test patients using the BERTEC Vision Advantage System. This protocol includes testing older adults with the BERTEC Vision Advantage system while sitting and standing. We want to determine if there is an effect on the data whether participants are sitting or standing. Our team has developed a test protocol, incorporating tests of vision, including the BERTEC Vision Advantage system, the Freiberg Visual Acuity Test (FrACT) to test contrast sensitivity, and the Howard Dolman Test of depth perception, as well as dynamic and standing balance, using the Timed up and go (TUG) Test, and the Berg Balance Scale. The specific aim of our project is to test older adults both with and without multifocal lens glasses to determine their effect on vision, depth perception, VOR, and their relation to balance.
