A compound of specific bioactive products from a major family of enzymes reduced the severity of age-related macular degeneration (AMD) in a preclinical model, according to a new study led by Massachusetts Eye and Ear researchers.
A new University of Liverpool study, published in Brain and Behaviour, identifies simple measures that could substantially improve the quality of life of stroke survivors with visual impairments.
In a nationally representative sample of older US adults, visual impairment was associated with worse cognitive function, according to a study published by JAMA Ophthalmology
Like the rest of the body, the brain loses flexibility with age, impacting the ability to learn, remember, and adapt. Now, scientists at University of Utah Health report they can rejuvenate the plasticity of the mouse brain, specifically in the visual cortex. Published today in PNAS, the study shows that manipulating a single gene triggers the shift, revealing it as a target for new treatments to recover the brain's youthful potential.
Where are baseball batters looking during the fraction of a second when a pitched ball is in their air? Their visual tracking strategies differ depending on whether they're swinging at the pitch, reports a study in the August issue of Optometry and Vision Science, the official journal of the American Academy of Optometry. The journal is published by Wolters Kluwer.
A new study by researchers at the University of Houston College of Optometry, published in Ophthalmic & Physiological Optics, found that blue light emitted from digital devices could contribute to the high prevalence of reported sleep dysfunction.
Football officials watching slow-motion clips or drivers changing from motorways to 30 mph zones could be unconsciously misjudging speed -- and the motivations behind a person's movements -- because their perceptions of 'normal' have been altered by recent experiences, new research has found.
Computer simulations of electrical charges sent to retinal implants based on fractal geometry have University of Oregon researchers moving forward with their eyes focused on biological testing.
Scientists have succeeded in regenerating functional retinal cells in adult mice. Like humans, mice cannot repair damage to their retinas. However, because zebrafish can, researchers created in mice a version of the fish gene responsible for turning Muller glia into retinal cells if eye injury occurs. Researchers found way to prevent the gene's activity from being blocked as the mice got older. The new interneurons formed connections and reacted normally to signals from light-detecting cells in the retina.
A research team from the Schepens Eye Research Institute of Massachusetts Eye and Ear has successfully prevented mice from developing angiogenesis of the retina--the sensory tissue at the back of the eye--using gene-editing techniques with CRISPR-Cas9.
