Over the past 10 years, a literature has emerged concerning the sex steroid hormone oestrogen and its role in human vision. Herein, we review evidence that oestrogen (oestradiol) levels may significantly affect ocular function and low-level vision, particularly in older females. In doing so, we have examined a number of vision-related disorders including dry eye, cataract, increased intraocular...

Vision therapy and rehabilitation have been used to successfully treat a wide range of visual disorders for over 90 years. Eye exercises are considered as one of the vision therapy-based program. Myopia as a refractive defect of the eye could be controlled through the use of vision therapy. The purpose of this study was to investigate the effectiveness of specifically designed eye exercises pro...

BACKGROUND Photoscreening and remote autorefraction showed promise in the urban "Vision in PreSchoolers Study." We transported a comparative screening with confirmation program to a remote part of interior Alaska. METHODS Eighty children from villages in the Koyukon region received onsite three-pronged vision screening followed by gold-standard confirmatory exams. Each had patched HOTV acuity...

CONTEXT Age-related macular degeneration is a prevalent disease of aging that may cause irreversible vision loss, disability, and depression. The latter is rarely recognized or treated in ophthalmologic settings. OBJECTIVE To determine whether problem-solving treatment can prevent depressive disorders in patients with recent vision loss. DESIGN Randomized, controlled trial. SETTING Outpat...

Neurology treats brain and spinal cord problems. Neurological devices that improve hearing vision can diagnose, prevent, treat many neurological disorders conditions, including Alzheimer's, Parkinson's, major depression, epilepsy, injury, damage. Neurovascular stents for aneurysms are a promising new treatment. This article discusses the latest US device regulatory framework marketing approval ...

according to specificity of practice hypothesis, availability of visual information during practice induces performance decrement in no-vision transfer test. one hypothesis is that full vision as a dominant source of information prevents the processing of other sensory sources, in which case, weakened vision may reduce dominance of vision over other sensory sources. the aim of the current study...

The ability to navigate without getting lost is an important aspect of quality of life. In 5 studies, we evaluated how spatial learning is affected by the increased demands of keeping oneself safe while walking with degraded vision (mobility monitoring). We proposed that safe low vision mobility requires attentional resources, providing competition for those needed to learn a new environment. I...
