Abstract Background Common paediatric perimetry techniques require central fixation and subjective responses, which may be challenging for young or cognitively impaired children. The Saccadic Vector Optokinetic Perimeter (SVOP) was designed to overcome these challenges by using infra‐red eye tracking to...
Abstract Background Visual impairment is globally among the most prevalent disabilities. Research concerning the health consequences of visual deficits is challenged by confounding effects of age, because visual impairment becomes more prevalent with age. This study investigates the influence of...
Abstract Reading is slow and difficult for people with central vision loss who must rely on their peripheral vision. It has been shown that practicing on a letter-recognition task can increase peripheral reading speed, and that the training-related improvement is...
Highlights • Playing a custom child friendly action videogame resulted in improved visual acuity. • Improvement of 1.4 lines after 20 h compared to more than 100 h of patching. • The action videogame approach may be an effective adjunct treatment for amblyopia....
Background To determine the test‐retest reproducibility of accommodative facility (AF) measures in an unselected sample of UK primary school children. Methods Using ±2.00 DS flippers and a viewing distance of 40 cm, AF was measured in 136 children (range 4–12 years, average...
SIGNIFICANCE Currently, treatments for amblyopia are occlusion or penalization of the stronger fellow eye. Fewer than 30% of patients improve stereoacuity using these treatments. In order to improve these outcomes, this group proposes a treatment to stimulate the stereoacuity through perceptual...
SIGNIFICANCE Prior studies have demonstrated the effectiveness of vergence-accommodative therapy in the treatment of convergence insufficiency (CI). These results show the changes in brain activation following therapy through the use of functional magnetic resonance imaging (fMRI). PURPOSE The purpose of this study...
Abstract Coloured overlays or lenses are widely available for use by children and adults with difficulties or discomfort while reading. In recent years, systematic reviews have been conducted in an attempt to establish the strength of the evidence base for...
Abstract Purpose This pilot study sought to determine the efficacy of using the Developmental Eye Movement (DEM) test in the adult, acquired brain injury (ABI) population to quantify clinically the effects of controlled, laboratory-performed, oculomotor-based vision therapy/vision rehabilitation. Methods Nine...
Abstract Background To evaluate the impact of treatment of symptomatic convergence insufficiency using office‐based vergence/accommodative therapy on reading skills in children. Methods Children (n = 44) ages nine to 17 years with symptomatic convergence insufficiency were administered the following four reading tests: Wechsler...
Abstract Traditional perceptual learning protocols rely almost exclusively on long periods of uninterrupted fixation. Taking a first step towards understanding perceptual learning in natural vision, we had observers report the orientation of a briefly flashed stimulus (clockwise or counterclockwise from...
Abstract Purpose To report the frequency of binocular vision (BV) anomalies in children with specific learning disorders (SLD) and to assess the efficacy of vision therapy (VT) in children with a non-strabismic binocular vision anomaly (NSBVA). Methods The study was...
Abstract This study investigated the influence of five days of moderate intensity aerobic exercise on the acquisition and consolidation of visual perceptual learning using a motion direction discrimination (MDD) task. The timing of exercise relative to learning was manipulated by...
How post-saccadic target blanking affects the detection of stimulus displacements across saccades Abstract When a visual stimulus is displaced during a saccade the displacement is often not noticed unless it is large compared to the amplitude of the eye movement. Displacement detection is...
Abstract Israeli Air Force (IAF) pilots continue flying combat missions after the symptoms of natural near-vision deterioration, termed presbyopia, begin to be noticeable. Because modern pilots rely on the displays of the aircraft control and performance instruments, near visual acuity...
Abstract Purpose To compare visual acuity (VA) improvement in teenagers with amblyopia treated with a binocular iPad game versus part-time patching. Methods One hundred participants aged 13 to <17 years (mean 14.3 years) with amblyopia (20/40 to 20/200, mean ∼20/63)...
Abstract We study optical technologies for viewer-tracked autostereoscopic 3D display (VTA3D), which provides improved 3D image quality and extended viewing range. In particular, we utilize a technique—the so-called dynamic fusion of viewing zone (DFVZ)—for each 3D optical line to realize...
Background: Reading from tablets is fundamental to modern culture. This study measured differences in the blink rate and symptoms of ocular discomfort in healthy participants during reading from a tablet and a paper book. Methods: Forty healthy, normal males subjects were recruited...
Commento CD SOPTIPubblicazione scientifica peer-review a firma anche della Segretaria SOPTI Tiziana Ruffinatto, insieme a Assunta Di Vizio e a Fabrizio Zeri, optometristi italiani. E' di ulteriore stimolo per cercare di finalizzare il lavoro di studio, clinica e di ricerca...
It is commonly assumed that saccades in the dark are slower than saccades in a lit room. Early studies that investigated this issue using electrooculography (EOG) often compared memory guided saccades in darkness to visually guided saccades in an illuminated...
Abstract Background Ocular dominance can be defined as the preference of an individual for viewing with one eye over the other for particular visual tasks. It is relevant to monovision contact lens wear, cataract surgery and sports vision. Clinically, the...

http://www.jovr.org/article.aspissn=2008322X;year=2017;volume=12;issue=2;spage=187;epage=192;aulast=Jang Abstract Purpose: To determine the effectiveness of vision therapy among Korean elementary school children with convergence insufficiency. Methods: A total of 235 elementary schoolchildren, 10.13 ± 2.45 years of age, were subjected to thorough eye examination including binocular vision...
http://www.sciencedirect.com/science/article/pii/S0042698916301432 Abstract The purpose of this study was to investigate whether a reduction of the accommodative lag is possible by training the accuracy of accommodation using auditory biofeedback. Accommodation responses were measured in thirty-one young adults with myopia for dioptric...
http://onlinelibrary.wiley.com/doi/10.1111/cxo.12469/abstract Articolo Open Access Purpose: The aim was to evaluate the repeatability of dynamic measurement of the accommodative stimulus–response curve (ASRC) at three different dioptric speeds using a modified instrument and its agreement with two other methods. Methods: Twenty-nine adults (23.5 ...
