Telerehabilitation included loaner equipment for Zoom videoconferencing with remote...

This longitudinal study highlights the psychological and functional problems that can result from maxillofacial trauma. is first to report outcome at one year. A total of 147 patients admitted for surgery following facial trauma were recruited over a seven-month period. Three questionnaires used record patient-derived levels dysfunction: Hospital Anxiety Depression scale, modified University Washington Quality Life questionnaire five non-validated items. At year 46 (31%) responded. Although...

SIGNIFICANCE A majority of visually impaired older adults were able to learn proficiently use visual-assistive iPhone applications (apps) following a median 1 hour and/or multiple training sessions, which should be considered when planning vision rehabilitation service delivery, including the option for remote telerehabilitation those who prefer that modality. PURPOSE Older with low are increasingly using technology improve their visual functioning. We examined whether age-related...

People with albinism (PwA) are known to have visual impairments; however, little is about whether these functions disrupted across earlier and later stages of the pathway. We investigated distinct perceptual fixation stability within each observer compared data age- (±5 years) sex-matched controls.

SIGNIFICANCE Identification of modifiable barriers to low vision rehabilitation (LVR) can inform efforts improve practice management patients with (LV), through, for example, targeted educational programs optometrists who do not LVR. PURPOSE Mild loss (20/25 20/70) is increasing in prevalence among the aging population, yet it unclear whether near-reading complaints (the highest presenting chief complaint) are being addressed. Studies LVR provision by U.S. currently lacking. This study...

Purpose: We examined different methods to reduce the burden of accessing technology for videoconferencing during telerehabilitation magnification devices visually impaired. Methods: During studies over past 5 years, vision rehabilitation providers assessed and gave training impaired participants with newly dispensed at home who connected Zoom via loaner tablets or smartphones assistance from (phase 1; n = 10) investigators by phone, 2; 11) local Lions Club volunteers in participants' homes,...

Abstract A significant number of young people throughout the world are experiencing mental health concerns. Many will develop their first concerns or be managing symptoms while enrolled in institutions higher education. Although many colleges and universities aware needs among students, psychosocial students often exceed availability resources cultural contextual barriers, such as stigma, may further impede access to care. Such gaps barriers lead poor prognosis well negative educational...

While general self-efficacy is known to relate achievement in many areas, it has rarely been evaluated individuals with low vision. Here we explore the psychometric properties and targeting of New General Self Efficacy Scale (NGSES) using Rasch analysis data collected from older adult clinical trial participants Participants (n = 121) completed pre-intervention telephone questionnaires (i.e., NGSES, Activity Inventory (AI), Beck Depression (BDI), SF-36, Telephone Interview for Cognitive...

Device utilization and abandonment for patients seen on a mobile clinic are explored. Findings informative resource allocation in novel low vision rehabilitation (LVR) delivery model. This study also explores the relationships between device LVR patient-reported functional outcomes.This prospective cohort investigated model.A questionnaire was administered by telephone 3 months 1 year after LVR. Participants (n = 65) had previously met U.S. definition of legal blindness were prescribed total...

Purpose: Advanced driver assistance systems (ADAS) have been reported to improve the safety of elderly and normally sighted drivers. The purpose this study was assess exposure to, perceived of, comfort level with, interest in using ADAS among drivers with age-related macular degeneration (AMD). Methods: Current aged 60+ years were recruited at four US sites complete a survey about driving habits. Frequency use and/or perceptions eight investigated. An avoidance score generated questions...

Unilateral peripheral prisms for homonymous hemianopia (HH) place different images on corresponding retinal points, a rivalrous situation in which local suppression of the prism image could occur and thus limit device functionality. Detection with has primarily been evaluated using conventional perimetry, where binocular rivalry is unlikely to occur. We quantified detection over more visually complex backgrounds examined effects ocular dominance.Detection rates eight participants HH or...
