Cognitive tests that rely on vision-dependent tasks may skew results for up to 25% of adults over 50 with undiagnosed visual problems such as AMD and cataracts. This may lead to a misdiagnosis of mild cognitive impairment in older adults.
By the time most of us hit our 40s, our close-up vision starts to decline and we develop presbyopia. A new eye drop called Vuity claims to alleviate the symptoms of presbyopia, allowing people to gain clearer vision without the need for glasses or surgery. Researchers examine the potential benefits of using Vuity for people with presbyopia.
Focused ultrasound technology that stimulates the retina may help those with blindness to regain their vision.
Antabuse, a drug commonly prescribed to treat alcohol use disorder, may help to restore eyesight in people with genetic retinitis pigmentosa and other disorders associated with retinal degeneration.
The ability of retinal cells to "wall off" damage may be key to preserving vision.
Eating a handful of dried goji berries five times a week may help delay or even prevent the onset of age-related macular degeneration. Over a 90 day period, those who ate goji berries had an increase in protective pigments in their eyes.
For those with a genetic predisposition to higher eye pressure, high caffeine consumption may increase the risk of developing glaucoma threefold.
Study confirms learning click-based echolocation can help those experiencing vision loss to maintain mobility while providing a sense of independence.
Older adults with visual impairments are 1.3 times more likely to develop mild cognitive impairment, often considered a precursor to Alzheimer's disease, than those with no significant vision loss.
The prevalence of depression and anxiety was between 2 and 2.56 higher in women experiencing sensory loss than men. Sensory loss was categorized as hearing loss, visual problems, or dual sensory loss.
Gene therapy that targets retinal ganglion cells with light-sensitive cone opsins helps restore vision in mice. Researchers report a potential human treatment could be available within three years.
Researchers report persistent psychological stress can contribute to the development and progression of vision loss.
