Previous studies revealed that people with binocular vision disorders have poor postural stability. However, most of the research was performed only on children and under binocular viewing condition, that could negatively affect the results. The aim of the current study was to investigate the influence of extra-ocular proprioceptive signals on postural stability in young adults with binocular v...

Optometrists have raised concerns about the use of Irlen filters/ lenses because of the striking similarity between the symptoms associated with accommodative, binocular and ocular motility disorders and the symptoms associated with the scotopic sensitivity syndrome described by Irlen. This article provides evidence demonstrating that Irlen filter candidates often have unidentified vision disor...

We've been finding possible association of central vision damage with binocular vision disorders in our clients suffering from age-related macular degeneration (ARMD), but whose visual acuity still allowed us to examine their binocular vision. Our findings show that there is a significant number of patients with heterophoria in horizontal, as well as vertical direction. The clients rate the vis...

Sight is the basic sense for drivers. Condition of the eye determines correct, comfortable and safe performance of the work as drivers. This article presents various factors influencing the sight condition. There are two groups of factors, external (environment, the kind and time of work, stress caused by work) and internal (systemic and local disorders). All these factors can reduce significan...

PURPOSE Tests of vision for mice remain limited and the visual phenotype of some retinal disorders in mice remain poorly understood. A novel assay of vision was used to determine how the form and extent of retinal disease affects visual phenotype in mice. METHODS Retinal histology, the suppression of locomotion by light and visual guidance of locomotion, were assessed in mice with progressive...

This survey of Geneva, and its surrounding areas’ medical professionals (Pediatricians, Orthopedic Surgeons, and Ophthalmologists) addressed four questions. First, in the past three years has a physician treated or referred any early stage discomfort; musculoskeletal or vision disorders in children/ adolescents caused by environmental and/or behavioral practices; age of children, amount of chil...

ABSTRACT A retrospective review of records determined the frequency and causes of low vision and blindness in all children aged < 16 years attending an ophthalmic practice in Sana'a, Yemen between January and December 2001. Of the 1104 children studied, 45 (4.1%) were found to have bilateral blindness and 115 (10.4%) were unilaterally blind; 48 children (4.3%) were bilaterally visually impaired...

BACKGROUND Communication is an integral part of human behaviour. Communication disorders are associated mainly with impairment in hearing, vision, and/or speech, which influences the ability to receive, comprehend, produce, and express verbal, nonverbal, and graphic information. When unrecognized and unmanaged, these very often "invisible" conditions can have a significant detrimental effect on...
