Uncovering the Hidden Population in Low Vision: A 10-year look at the benefits of a driving program for a student-parent workshop

Cynthia Bachofer, PhD, CLVT

Driving is a teenager’s dream and having low vision may get in the way of that dream. Information on the potential use of bioptics for the novice driver is difficult to find, conflicting or inaccurate. A student-parent workshop developed at a statewide school for the visually impaired that focuses on safe driving with low vision has taken place for over a decade. Conversations at the conclusion of the workshop emphasized that this group of young adults was a hidden population. They often strive to pass as typically sighted and were not linked to resources and available programming.

Perception & utilization of a Smartphone Magnifier App by Visually-Impaired Seniors

Jeffrey K. Ho, OD; Nicole C. Ross, OD; Alexis G. Malkin, OD; Max Estabrook; Cecilia Idman-Rait, MPH; Ava K. Bittner, OD, PhD

Mobile applications (apps) have become increasingly important for everyday life and can offer additional accessibility for patients with visual impairment. We sought to determine whether and how older adults with low vision would utilize a free mobile application (app) that provides electronic magnification, as well as gauge their preferences for the magnifier app compared to other types of visual aids. Visually-impaired seniors used the SuperVision+ app on a loaner iPhone for a 3-month period. App ratings and usage were self reported by subjects in a phone survey administered by investigators. The magnification app was preferred and rated as excellent or good by most visually-impaired seniors who compared it to their smartphone camera. Targeted interventions may be needed to support the use of magnifier apps outside the home by older seniors.

Postural control declines in older adults with visual impairment and in normally sighted older adults under cognitive load

Aaron P. Johnson, PhD; Caitlin Murphy, PhD, CLVT; Berkley Petersen; Karen Li, PhD

Falls are more likely in older persons, particularly those with vision impairments. Executive capabilities deteriorate with age, and dual-task studies have shown that older persons' postural instability increases when undertaking a cognitive task. However, the impact of cognitive stress on postural stability in visually impaired older persons is little understood. The current study looks at the individual and combined effects of cognitive load and visual impairment on postural stability in older people.
