Vision impairments are highly prevalent after acquired brain injury (ABI). Conceptual models that focus on constructing intellectual frameworks greatly facilitate comprehension and implementation of practice guidelines in an interprofessional setting. The purpose of this article is to provide a review of the vision literature in ABI, describe a conceptual model for vision rehabilitation, explain its potential clinical inferences, and discuss its translation into rehabilitation across multiple practice settings and disciplines...

PURPOSE: Low vision rehabilitation (LVR) is a pertinent context for integrating early, evidence-based psychological interventions given the high prevalence of untreated depression in adults with vision impairment. This study aims to identify the perceived barriers and facilitators to staff-delivered telephone-based problem-solving treatment for primary care (PST-PC) offered as an integrated component of LVR. METHODS: Qualitative semi-structured interviews, developed using the theoretical domains framework (TDF) and Consolidated Framework for Implementation Research (CFIR), were conducted with 21 LVR professionals and a clinical psychologist involved in the delivery of PST-PC...

PURPOSE: While the impact of visual impairments on specific aspects of young adults' lives is well recognised, a systematic understanding of its impact on all life aspects is lacking. This study aims to provide an overview of life aspects affected by visual impairment in young adults (aged 18-25 years) using a concept-mapping approach. METHOD: Visually impaired young adults (n = 22) and rehabilitation professionals (n = 16) participated in online concept-mapping workshops (brainstorm procedure), to explore how having a visual impairment influences the lives of young adults...

Spatial resolution is an important factor for human pattern recognition. In particular, low resolution (blur) is a defining characteristic of low vision. Here, we examined spatial (field of view) and temporal (stimulus duration) requirements for blurry object recognition. The spatial resolution of an image such as letter or face, was manipulated with a low-pass filter. In experiment 1, studying spatial requirement, observers viewed a fixed-size object through a window of varying sizes, which was repositioned until object identification (moving window paradigm)...

PURPOSE: The prevalence of dementia and ocular pathology increases with age and many older individuals affected by such diseases are being institutionalised. The objectives of this systematic review are to describe the level of eye care services being offered to older institutionalised individuals, present the prevalence of visual impairment in those with dementia, and describe the interventions offered to visually impaired residents with dementia. METHODS: A literature review was performed in four relevant databases, limited to peer-reviewed journals published in English and French, between the years 1984 and 2014...

A 4-year-old girl presented with a history of poor vision and oscillation of both eyes since infancy. Ocular examination revealed the best corrected visual acuity of 2/60 in right eye and 3/60 in left eye. Horizontal pendular nystagmus was present in both eyes. Fundus examination revealed morning glory disc anomaly (MGDA) bilaterally. Radiographic imaging of the brain revealed central nervous system anomalies. The guarded visual prognosis was explained and the patient referred for low vision rehabilitation and advised yearly follow-up...

PURPOSE: In this paper, we have sought to stimulate a critical dialog regarding the ways in which disability has been largely conceptualized and studied in literature addressing age-related vision loss (ARVL). We suggest an expansion of this largely biomedically informed research area to include alternative frameworks, namely critical disability perspectives. METHOD: To demonstrate the potential contributions of adopting a critical disability approach to enhance understandings of ARVL, this article outlined the primary tenets of the biomedical and social models of disability; the key aims, emphases, and assumptions of critical disability perspectives; and provided examples of how such an approach would lead to new research foci in the study of ARVL...

Visual impairments are common after traumatic brain injury (TBI) and negatively affect quality of life. We describe a 39-year-old woman with a severe TBI who was evaluated by the inpatient optometry and vision rehabilitation service with findings of complete right homonymous hemianopia and right cranial nerve III palsy with 30-degree right exotropia (eye turn out) and complete right ptosis (eyelid will not open). The 30-degree exotropia advantageously generated 30 degrees of right visual field expansion when the right ptosis was treated with a magnetic levator prosthesis, which restores eyelid opening...

Low-vision rehabilitation (LVR) aims to improve the functioning of patients with chronic uncorrectable visual impairment. LVR is inherently a patient-centered intervention since its approach and goals are dictated by the needs and abilities of each individual patient. Accordingly, it is essential to have patient-centered outcome (PCO) measures to assess and compare the efficacy and effectiveness of low-vision interventions; however, there is a lack of evidence on the effectiveness of LVR interventions. We reviewed the literature in order to identify randomized controlled trials (RCTs) in the field of LVR and the outcome measures used to assess patient functioning in these trials...

Caregiving has evolved as an important issue not only for those receiving care, but for those providing it as well. While caregiving allows those with disabilities to better adapt, it has been shown to take a toll on the caregiver on various levels, such as invoking depression and burden. The purpose of this study was to perform a systematic review of the literature pertaining to depression and burden among caregivers of patients with visual impairment. A comprehensive literature search using multiple databases was conducted to include all articles on burden of care or depression among the caregivers of the visually impaired...
