OBJECTIVE In previous studies about the control of posture there have been controversial findings. Our aim was to examine the role of monocular and binocular vision in controlling posture in quiet stance. METHODS Twenty-eight normal subjects were tested. We used a force platform in measuring postural stability. In main experiment, postural stability was measured in four conditions: both eyes ...

AIM To determine the repeatability and agreement of stereoacuity measurements made using some of the most widely used clinical tests: Frisby, TNO, Randot and Titmus. METHODS Stereoacuity was measured in two different sessions separated by a time interval of at least 24h but no longer than 1wk in 74 subjects of mean age 20.6y using the four methods. The study participants were divided into two...

Studies by Scheiman et al. on a clinical paediatric population1 and Lara et al. on a clinic population aged 10–35 years2 reported that the most common vision disorder after ametropia was binocular vision disorders. In comparison with certain ocular diseases also, binocular vision disorders are regularly diagnosed.3 Vergence disorders (binocular vision disorders4 functionally classified descript...

PURPOSE To compare binocularity in central and peripheral vision of people with early-onset strabismus and people with normal binocular vision. METHODS Ten subjects with early-onset strabismus, and nine subjects with normal binocular vision were tested. To assess binocularity, interocular transfer (IOT) of a rotary movement aftereffect (MAE) was measured. The MAE stimuli were either confined ...

PURPOSE To our knowledge, studies comparing binocular eye movements during reading task in strabismic children are scarce. The goal of our study was to examine binocular coordination of saccades during reading in strabismic children. METHODS Binocular eye movements were recorded by an infrared system (mobile EBT) in 18 strabismic children 6.8 to 16 years old (mean age 10.2 ± 3) who were asked...

We investigated suprathreshold binocular combination in humans with abnormal binocular visual experience early in life. In the first experiment we presented the two eyes with equal but opposite phase shifted sine waves and measured the perceived phase of the cyclopean sine wave. Normal observers have balanced vision between the two eyes when the two eyes' images have equal contrast (i.e., both...

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 carried out at a centre for learning disability (LD). Comprehensive eye examination and binocular vision assessment was carried out for 9...

With the rapid development of industrial cameras, binocular stereo vision is widely used in the field of manufacturing. Using two or more image points of one point in space to restore space depth information is called stereo vision, which process is known as three-dimensional reconstruction. Binocular stereo vision is normally used in the static test and has been rarely reported for the dynamic...
