The Effect of Visual Impairment on Balance and Mobility in Adults Over Age 50
Kierstyn Napier-Dovorany, OD; Victoria Graham, PT, DPT, OCS, NCS
Visual impairment (VI) is linked to fall risk in the elderly, and poor health in younger adults. We convened an interdisciplinary team of researchers with expertise in vision and mobility to focus our efforts on best practices in the study of VI and physical mobility. A case control study compared balance and walking function between adults with juvenile onset VI (beginning before age 18), those with adult onset VI (beginning after age 18), and an age and gender matched control group without VI.

Clinical Evaluation of the Hybrid Image Display of Oculenz: An Augmented Reality Headset for Age-related Macular Degeneration
Linda Lam, MD MBA; Thomas Finley, MD; Scott Hewitt, COT, CRC, CRA; Deborah Hardison, COMT, OSA; Michael Freeman, JD; Mitchael Freeman
A new hardware and software augmented reality (AR) heads-up display (HUD) headset “Oculenz” has been designed to meet multiple needs at distance and near for patients who have Advanced Macular Degeneration as evidenced by monocular or binocular scotoma(s). The purpose of the study was to explore the capabilities and efficacy of the Oculenz Self-Calibration Visual Field Edge Detection Test and the resulting Modified Real-Time Streaming Video (MRTSV) with AMD subjects when performing tasks such reading the logMAR chart, reading paragraphs from the Contemporaneous Near Eye Chart (CNEC), and facial recognition.

Real World Use of the Eye-01 Augmented Reality Visual Aid
Rebecca Kammer, OD, PhD
A new augmented reality (AR) spectacle or head mounted device, Eye-01, has been designed to meet multiple needs at distance, intermediate, and near and essentially replace multiple unique devices. The purpose of the study is to explore the lived experience of users when at home on their own for 2 weeks or more. User data extracted from the device (times of use, settings) was compared to descriptions of use during one-on-one interviews.

Are Patterns of Magnifier Selection Changing in Low Vision Patients?
Donald Fletcher, MD; Ron Schuchard, PhD
Optical and electronic/digital magnifiers are available for providing assistance to low vision patients in reading and other detail tasks. The array of electronic devices has expanded greatly in last several years and prices have dropped significantly. This study shows a pattern of low vision patients selecting a much higher proportion of electronic magnifiers than 5 years ago in 2013.

Educational Attainment, Missed Clinical Appointments, and Visual Acuity in Age-related Macular Degeneration
Rebecca Deffler, OD; San-San Cooley, OD; Fredrick Davidorf, MD; Bradley Dougherty, OD, PhD
Age-related macular degeneration (AMD) is a leading cause of blindness in older adults. We have previously found that socioeconomic status (SES), as represented by educational achievement, is inversely related to visual acuity in people being treated for AMD. The purpose of this study was to evaluate possible mechanisms for this relationship in patients with AMD, specifically attendance at scheduled clinical appointments with a retina specialist, access to transportation, and driving licensure.
