INTRODUCTION: Twenty-five years after the Americans with Disabilities Act, there has still been a lack of advancement of accessibility in healthcare for people with visual impairments, particularly older adults with low vision. This study aims to advance understanding of how older adults with low vision obtain, process, and use health information and services, and to seek opportunities of information technology to support them. METHODS: A convenience sample of 10 older adults with low vision participated in semi-structured phone interviews, which were audio-recorded and transcribed verbatim for analysis...

Persons with an intellectual disability are at risk of developing separation anxiety and, if left untreated, this can be a risk factor for the development of psychopathology. The effects of an intervention, namely Technology Assisted Therapy for Separation Anxiety (TTSA), were examined on the separation anxiety, challenging behavior, psychosocial functioning and quality of life experienced by moderate to mild intellectually and visually disabled adults. This study aimed to determine whether TTSA reduces separation anxiety and challenging behavior in persons with intellectual disability and visual impairment, and if this results in increased psychosocial functioning and quality of life...

PURPOSE: To study if peripheral vascular leakage (PVL) on ultra-widefield fluorescein angiography (UWFFA) prognosticates complications of uveitis or necessitates treatment augmentation. METHODS: Retrospective cohort study of uveitis patients imaged with UWFFA and ≥1 yr of follow-up. RESULTS: We included 73 eyes of 42 patients with uveitis. There was no difference in baseline, intermediate, final visual acuity (p = 0.47-0.95) or rates of cystoid macular edema (CME) (p = 0...

INTRODUCTION: Maroteaux-Lamy syndrome (MLS) is a rare progressive condition characterized by inflammation and scarring of multiple organs. Ocular complications caused by anterior segment abnormalities commonly cause visual impairment in MLS. Angle-closure glaucoma is one such complication, but there are limited data on presentation, workup, and management of this condition. CASE PRESENTATION: This case report describes an atypical presentation of acute angle-closure glaucoma in a patient with MLS despite a prior prophylactic laser peripheral iridotomy-which would typically prevent an acute angle-closure attack-that was patent and intact at the time of angle closure...

Aviv M Weinstein
There are a growing number of studies on structural and functional brain mechanisms underlying Internet gaming disorder (IGD). Recent functional magnetic resonance imaging studies showed that IGD adolescents and adults had reduced gray matter volume in regions associated with attention motor coordination executive function and perception. Adolescents with IGD showed lower white matter (WM) integrity measures in several brain regions that are involved in decision-making, behavioral inhibition, and emotional regulation...

BACKGROUND: Visual impairment (VI) and hearing impairment (HI) are the two most common types of sensory disability encountered clinically. However, VI and HI result in different limitations in daily life. We assessed the level of functioning in patients with VI or HI based on the International Classification of Functioning, Disability, and Health. METHODS: This nationwide, cross-sectional study included 312 people with VI and 540 people with HI. Each participant's degree of functioning and disability was evaluated using the World Health Organization Disability Assessment Schedule 2...

Sensory processing deficits are core features of schizophrenia, reflected in impaired generation of event-related potential (ERP) measures such as auditory mismatch negativity (MMN) and visual P1. To understand the potential time course of development of deficits in schizophrenia, we obtained MMN to unattended duration, intensity and frequency deviants, and visual P1 to attended LSF stimuli, in 43 healthy individuals ages 6 to 25years (mean 17), and compared results to data from 30 adult schizophrenia patients (mean age 38)...

BACKGROUND: Neurodevelopmental impairments have frequently been described in children and adolescents with dextro-transposition of the great arteries (d-TGA). The arterial switch operation (ASO) to correct d-TGA has been used for more than 30 years, and more than 90% of these patients now reach adulthood. However, very little is known about their long-term functional outcomes. The present study investigated neurocognitive outcomes and the prevalence of psychiatric disorders in adults with d-TGA corrected by ASO...

BACKGROUND: Contemporary data for causes of vision impairment and blindness form an important basis of recommendations in public health policies. Refreshment of the Global Vision Database with recently published data sources permitted modelling of cause of vision loss data from 1990 to 2015, further disaggregation by cause, and forecasts to 2020. METHODS: In this systematic review and meta-analysis, we analysed published and unpublished population-based data for the causes of vision impairment and blindness from 1980 to 2014...

During endocytosis, molecules are internalized by the cell through the invagination of the plasma membrane. Endocytosis is required for proper cell function and for normal development in Drosophila. One component of the endocytic pathway is the retromer complex, which recycles transmembrane proteins to other parts of the cell such as the plasma membrane and the trans-Golgi network. Previous studies have shown that mutations to the retromer complex result in developmental defects in Drosophila. In humans, retromer dysfunction has been implicated in Alzheimer's and Parkinson's disease, but little is known about the role of the retromer complex in Drosophila oogenesis...

The regular use of cannabis generates pronounced cognitive disorders, especially in users who begin before the age of 15-16. However, less is known about the impact of regular cannabis on visual function, especially in the case of early onset. Cannabinoid receptors (CB1) are expressed in areas of the visual system, like the thalamus and primary cortex, which might originate sensory disorders. Hence, we measured contrast sensitivity (CS) in three groups, i.e. cannabis users with late onset of cannabis use (after 16 years old), cannabis users with early onset"...

Motor imagery (MI) is a mental practice that reproduces the visual- and/or kinesthetic-modality brain activations accompanying movement. It is a useful rehabilitation technique as the affected motor cortex can be stimulated in patients with stroke and hemiplegia. However, most patients with stroke have difficulty with MI owing to advanced age and/or higher-cognitive dysfunction, thus impairing their ability to internally simulate the action. We therefore investigated whether action observation (AO), an alternative form of motor stimulation that works via the mirror-neuron system, could facilitate motor cortical activity in such patients...

OBJECTIVE: The relationship between insomnia symptoms and cognitive performance is unclear, particularly at the population level. We conducted the largest examination of this association to date through analysis of the UK Biobank, a large population-based sample of adults aged 40-69 years. We also sought to determine associations between cognitive performance and self-reported chronotype, sleep medication use and sleep duration. METHODS: This cross-sectional, population-based study involved 477,529 participants, comprising 133,314 patients with frequent insomnia symptoms (age: 57...

In addition to deficits in social communication, individuals diagnosed with Autism Spectrum Disorder (ASD) frequently exhibit changes in sensory and multisensory function. Recent evidence has focused on changes in audiovisual temporal processing, and has sought to relate these sensory-based changes to weaknesses in social communication. These changes in audiovisual temporal function manifest as differences in the temporal epoch or "window" within which paired auditory and visual stimuli are integrated or bound, with those with ASD exhibiting expanded audiovisual temporal binding windows (TBWs)...

Due to its unique evolutionary relevance, it is understood that pain automatically attracts attention. So far, such attentional bias has mainly been shown for pain-related stimuli whereas little is known about shifts in attentional focus following actual painful stimulation. This study investigated attentional shifts by assessing eye movements into the direction of painful stimulation. Healthy participants were presented either a blank screen or a picture showing a natural scene while painful electrical stimuli were applied to the left or right hand...

INTRODUCTION: Calcium is vital for the functioning of the inner ear hair cells as well as for the neurotransmitter release that triggers the generation of a nerve impulse. A reduction in calcium level could therefore impair the peripheric vestibular functioning. However, the outcome of balance assessment has rarely been explored in cases with osteopenia and osteoporosis, the medical conditions associated with reduction in calcium levels. OBJECTIVE: The present study aimed to investigate the impact of osteopenia and osteoporosis on the outcomes of behavioural and objective vestibular assessment tests...
