Although computer vision syndromes are becoming a major public health concern, less emphasis is given to them, particularly in developing countries. There are primary studies on different continents; ...
Understanding the prevalence of vision conditions in a population is critical for determining the most appropriate strategies for detecting and correcting eye conditions in a community. This is partic...
Although recent studies have provided detailed analyses of the prevalence of vision conditions in Aboriginal and/or Torres Strait Islander children in urban and regional areas of Australia, there is a...
Comprehensive eye examinations were provided to 193 primary school children in a very remote Australian region. Ninety eight percent of children identified as Aboriginal and/or Torres Strait Islander....
Although the average unaided vision in the population was good (mean: 0.02 ± 0.13 logMAR) and the prevalence of reduced unaided visual acuity (>0.3 logMAR in either eye) was low (4%), vision condition...
In this population of children in a very remote Australian region, up to 1 in 3 children had a vision condition, with many of these conditions being uncorrected and undetected. These findings highligh...
BACKGROUND Acquired pendular nystagmus (APN) is a back and forth, oscillatory eye movement in which the 2 oppositely directed slow phases have similar waveforms. APN occurs commonly in multiple sclero...
Prompt initiation of pulse glucocorticoid treatment is recommended in case of visual symptoms and suspected or proven giant cell arteritis (GCA). Pulse treatment in most cases prevents involvement of ...
Friedreich ataxia (FRDA) is an inherited condition caused by a GAA triplet repeat (GAA-TR) expansion in the FXN gene. Clinical features of FRDA include ataxia, cardiomyopathy, and in some, vision loss...
Using optical coherence tomography (OCT), we measured peripapillary retinal nerve fiber layer (RNFL) thickness in 198 people with FRDA, and 77 controls. Sloan letter charts were used to determine visu...
The majority of patients, including children, had pathologically thin RNFLs (mean = 73 ± 13 μm in FRDA; 98 ± 9 μm in controls) and low-contrast vision deficits early in the disease course. Variability...
These data suggest that both hypoplasia and subsequent degeneration of the RNFL may be responsible for the optic nerve dysfunction in FRDA and support the development of a vision-directed treatment fo...
Glial fibrillary acidic protein (GFAP) astrocytopathy is a steroid-responsive autoimmune meningoencephalomyelitis commonly preceded by a viral illness. It is clinically characterized by encephalopathy...
To report a novel case of GFAP astrocytopathy presenting with profound intracranial hypertension and bilateral vision loss....
Case report....
GFAP astrocytopathy should be considered when evaluating patients with intracranial hypertension or bilateral vision loss, particularly when other features of autoimmune encephalitis are present....
To evaluate the long term complications and vision loss in HLA-B27 uveitis....
Retrospective review of subjects with HLA-B27 uveitis in a public tertiary centre between January 2008 and 2020....
562 HLA-B27-positive subjects (834 eyes) had mean follow-up of 9.8 years (8173.2 eye-years). Median visual acuity at ten years was 0.1 logMAR (IQR 0.0-0.1). Complications occurred in 404 eyes (48.4%):...
Complications are frequent in HLA-B27 uveitis, especially in older subjects, chronic inflammation and intermediate uveitis. Despite this, the majority of subjects maintain good visual prognosis....
Quality of life (QoL) is a critical component of aftercare in survivors of childhood-onset craniopharyngioma (CP). Visual impairment adversely affects QoL after CP. This study assessed the frequency o...
Digital reading devices have become increasingly popular among people with low vision. Because displays come in many sizes ranging from smart watches to large desktop computer displays, it is importan...
The selection of effective digital displays for reading by people with low vision focuses attention on the interacting effects of print size, display size, font, visual acuity, and reading distance. T...
We emphasize two critical factors in selecting an appropriate reading display: angular print size, which should exceed the individual's critical print size, and display size, which should allow at lea...
Through an illustrative example, we demonstrate how our approach can be used to determine display size for a low-vision individual with 20/200 acuity and central field loss who wants to read at 30-cm ...
We provide a procedure to guide the selection of appropriate displays for a wide range of acuities. Our approach can help clinicians in making recommendations for their patients, digital product desig...
Transient visual loss (TVL) is a common complaint in the emergency department, with numerous possible etiologies. Prompt evaluation and management of TVL can potentially prevent progression to permane...
