Most people with low vision experience difficulty with reading. Reading assessment can provide guidance for prescription of reading aids and strategies for reading rehabilitation. Here we investigate the effectiveness of letter acuity (LA) and reading acuity (RA) as predictors of low-vision reading performance.
Optometric or visual acuity assessment is an essential part of ophthalmologic examination. Visual acuity measurement serves as a tool for screening of ophthalmic disorders, as well as diagnosis and monitoring of refractive errors and other causes of reduced acuity. Persons with diabetes may experience situations which impair visual acuity, or which impact the utility of refractive visual acuity assessment. This communication shares guidance as to when and when not to perform visual acuity charting in person...
When one eye does not function well during development, the visual cortex becomes less responsive to it and visual acuity declines. New research suggests that reduced response strength and deteriorating acuity occur in separate circuits.
This article reviews the basic physiology of visual acuity and the principles for its clinical measurement. It describes visual acuity and its limits as a function of the human eye. Referring to the new international standard ISO/FDIS8596:2017 it explains the conditions for standardized visual acuity testing. Furthermore, it gives detailed instruction on measuring visual acuity at distance and near, as well as in children, in low vision patients and for scientific purposes.
To investigate how well visual field sensitivity predicts visual acuity at the same locations in macular disease, and to assess whether such predictions may be useful for selecting an optimum area for fixation training.
The objective of our study was to compare the Cardiff Acuity Card© test (CAC test) (Kay Pictures Ltd) with the induced tropia test (ITT) in nonverbal children for the detection of monocular vision deficit. This is a retrospective case note review of 34 nonverbal children, aged 12-48 months, attending the pediatric ophthalmology clinic at Children's Hospital of Pittsburgh of UPMC between October 2014 and January 2015. 30/34 were included for analysis. Binocular visual acuity and monocular visual acuity wer...
Pure alexia is a deficit of reading affecting the ability to process a word's letters in parallel. Instead, a slow, effortful letter-by-letter reading strategy is employed. It has been claimed that a visual impairment caused the reading impairment. The present study compares visual processing and word reading of a patient with severe visuospatial deficits due to probable posterior cortical atrophy (PCA) to two patients with pure alexia. A double dissociation emerged between visual processing and word readin...
Hearing impairment, vision impairment, and dual impairment (both hearing and vision impairment), have been independently associated with functional and cognitive decline. In prior studies of dual impairment, vision impairment is generally not defined or defined by visual acuity alone. Glaucoma is a leading cause of blindness and does not affect visual acuity until late in the disease; instead, visual field loss is used to measure vision impairment from glaucoma.
Previous research has shown an age-related decline in Useful Field of View (UFOV) test performance, which measures the duration required to extract relevant information from a scene in three subtasks. However, these results are mostly based on data that may have been confounded by (age-related) ocular diseases. We examined UFOV performance in subjects aged 19.5 to 70.3 years to investigate how UFOV performance changes throughout adulthood. All subjects underwent a thorough ophthalmological examination to ex...
To evaluate foveal function in patients with inherited retinal degenerations (IRD) by measuring visual acuity (VA) after correction of higher-order aberrations.
The decrease in visual acuity under low luminance conditions is well known. Recent laboratory evidence showed that crowding under low luminance (mesopic) light levels is less robust than under photopic conditions. The present study examines whether such differences in crowding influence clinical measurements of mesopic visual acuity, including test-retest repeatability.
Children with Down syndrome (DS) typically have reduced visual acuity (VA) and accommodation lag, but it is unclear whether prescribed glasses should correct both distance VA (DVA) and near VA (NVA) due to the lack of RCTs. We therefore conducted a multicentre RCT to compare the effects of bifocals designed to correct both DVA and NVA with distance-correcting unifocal glasses in children with DS.
To study visual acuity, refractive errors, eccentric fixation, and reading performance in patients with toxoplasmic macular retinochoroiditis.
This study aimed to report normative reference data for a Dynamic Visual Acuity test while walking on treadmill. The protocol's suitability was assessed by investigating its test-retest reliability and its validity through the drop-out rate and verification of the frequency of head movements. Furthermore, the influence of age on visual acuity loss (VAL) was determined to reveal the need for age-specific reference data.
The article presents a rare clinical case of secondary epiretinal membrane (ERM) in a 67-years-old woman. The patient was diagnosed with ERM in the left eye after loss of vision complaints. One year prior to the visit the patient had underwent 2 sessions of laser photocoagulation for proliferative post-thrombotic retinopathy in the left eye. In the context of relatively high visual functions (decimal visual acuity of 0.7 at the time of the visit), observation strategy was carried out. The follow-up period w...
The aim of this study was to investigate static and dynamic visual acuity, refractive error, and the use of visual compensation of elite football players.
To investigate the predictive factors of visual acuity (VA) after cataract surgery in patients with retinitis pigmentosa (RP).
To determine the prevalence of reduced visual acuity and ocular disease in the children of migrant farmworkers in Georgia.
To evaluate the relationship between a novel spectral-domain optical coherence tomography (SD-OCT) parameter, predicted dry retinal volume (DRV), and visual acuity (VA) in subjects with diabetic macular edema.
The Reading Accessibility Index (ACC) has been proposed as a single-value reading parameter that can capture information on both reading speed and print sizes that can be read. It is defined as the average reading speed across a relevant range of print sizes (1.3-0.4logMAR), normalised by typical young-adult reading speed of 200wpm, and with values typically in the range of 0-1. This study determines the impact of low vision aids (LVAs) on reading by evaluating ACC values for visually impaired observers rea...
To explore various methods for assessing the early response to vascular endothelial growth factor (VEGF) inhibitors for neovascular age-related macular degeneration and investigate their association with 3 year visual acuity (VA) outcomes.
Abnormal binocular experience during infancy or childhood from strabismus and/or anisometropia results in visual acuity deficits (eg, amblyopia) and impaired stereoacuity. These pediatric eye conditions have also been linked to slow reading and fine motor impairment.
The appearance of tessellated fundus in an eye may act as a marker in identifying visual performance, degree of myopia or risk of progression of myopia in a given eye. A systematic literature search using key words was performed using PubMed, Web of Science and Google Scholar and of the 832 studies identified, 10 full-length articles, which met the inclusion criteria, were considered for review. The primary outcome measures were association of tessellated fundus with: (i) visual acuity, (ii) refractive erro...
To investigate the association between macular features on spectral-domain optical coherence tomography (SD-OCT) and visual acuity (VA) in Coats' disease.
Vision charts comprising single Lea symbols surrounded by either flanking bars or flanking Lea symbols are available for measurement of visual acuity in children. However, the results obtained with such charts may not be interchangeable owing to potential differences in the crowding effect.
