The Use of Vision Rehabilitation and Adapted Devices by People who Report Vision Impairment in the United States

Erica Shelton OD, MS; Megan Hurley OD; John Crews, DPA; Dean VanNasdale OD, PhD

This study analysis utilization of vision rehabilitation and adapted devices in the visually impaired population. Data obtained by the National Health Interview Survey through the Centers for Disease Control’s Vision and Eye Health Surveillance System is reviewed for a novel approach to the distribution of utilization for practitioners and policy makers alike.

Occupational therapists’ knowledge and behaviors regarding the provision of low vision services: Does rurality matter?

Pamela Lewis-Kipkulei, OTD, OTR/L; Amanda Carpenter, PhD; Holly Hertzberg, OTS; Jenna Lynn, OTS

Given the increase in the aging population, low vision practice and research is becoming a higher priority in occupational therapy (American Occupational Therapy Association, 2014). Low vision research is especially important in rural communities, given the number of disparities and fewer resources in health care (Rural Health Reform Policy Research Center, 2014). The goals of this study were two-fold. First, we sought to better understand OT knowledge and perceptions about low vision, and their effect on low vision evaluation and treatment. Second, we explored any differences between OTs that reported practicing in rural and urban counties, specifically in knowledge, perceptions, and behaviors related to low vision.

Assessing the geographic distribution of age-related eye diseases in the U.S. using Medicare Claims data from the Centers for Disease Control and Prevention’s Vision and Eye Health Surveillance System

Megan Hurley, OD; Erica Shelton, OD, MS; John E. Crews, DPA; Dean A. VanNasdale OD, PhD

National health surveillance systems have previously demonstrated geographic disparities in the prevalence of vision impairment and access to vision related services using survey data. In this study, we assess the geographic distribution and geographic disparities of diagnosed age-related eye diseases in the U.S. Medicare population using claims data from a newly developed national health surveillance data system to improve our understanding of these disparities.

Mediators of the Relationship between Socioeconomic Status and Visual Acuity in Age-related Macular Degeneration

Rebecca Deffler, OD; San-San Cooley, OD; Frederick 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 attainment, is inversely related to visual acuity in people being managed for AMD. Relationships between vision and SES are documented in the literature, but potential reasons for this relationship are not well understood. The purpose of this study was to evaluate for causal factors in the relationship between SES and vision in patients with AMD using mediation analysis.

Well-Being and Mental Health Factors among Informal Caregivers of Individuals with Visual Impairments

Callie Victor, PhD, OTR/L, CLA; Matthew Haase, MS, OTR/L, ATC; Michael Bown; Lindsey Bates, OTR; Michael Centra, OTR/L; Jaclyn Sachleben; Elizabeth Tyson; Michelle Gamber, DrPH; Suleiman Alibhai

Individuals with visual impairments often require the support of informal caregivers, and these caregivers routinely make personal, emotional, financial, and physical sacrifices to provide care and support for their loved one. Previous research has indicated that mental health factors, level of impairment, emotional regulation, and education all impact the quality of care provided by caregivers. The purpose of this study was to gain an understanding of the demands required, and supports needed, of informal caregivers for individuals with visual impairments.
