No Evidence That Calcium Increases Risk Of AMD

Eating a calcium-rich diet or taking calcium supplements does not appear to increase the risk of age-related macular degeneration (AMD); according to the findings of a study by scientists at the National Eye Institute (NEI). AMD is a leading cause of vision loss and blindness among people age 65 and older in the United States.…

AI Can Make Ophthalmologists More Effective

As artificial intelligence continues to evolve, diagnosing disease faster and potentially with greater accuracy than physicians; some have suggested that technology may soon replace tasks that physicians currently perform. But a new study from the Google AI research group shows that physicians and algorithms working together are more effective than either alone. It’s one of…

Gel Bonds To Eye

Repair Injuries: Adhesive Gel Bonds To Eye Surface

An adhesive gel packed with light-activated chemicals can seal cuts or ulcers on the cornea the clear surface of the eye and then encourage the regeneration of corneal tissue; according to a preclinical study published online today in Science Advances. The new technology, named GelCORE (gel for corneal regeneration); could one day reduce the need…

Retinal pigment epithelium

Long-Lived Patterns In Cells Of The Eye

Cells of the retinal pigment epithelium (RPE) form unique patterns that can be used to track changes in this important layer of tissue in the back of the eye; researchers at the National Eye Institute (NEI) have found. Using a combination of adaptive optics imaging and a fluorescent dye, the researchers used the RPE patterns…

Robot's Eyes Helps Those With Profound Motor Impairments

An interface system that uses augmented reality technology could help individuals with profound motor impairments operate a humanoid robot to feed themselves and perform routine personal care tasks such as scratching an itch and applying skin lotion. The web-based interface displays a “robot’s eye view” of surroundings to help users interact with the world through…

Vision loss

High Rate Of Visual Problems In Stroke Survivors

Visual impairment, also known as vision impairment or vision loss; is a decreased ability to see to a degree that causes problems not fixable by usual means, such as glasses. Some also include those who have a decreased ability to see because they do not have access to glasses or contact lenses. Visual impairment is often…

But what about the drawbacks? Here’s a major one: increased screen…

Wet Macular Degeneration

Need To Know About Wet Macular Degeneration

Macular degeneration is age-related macular degeneration (AMD or ARMD); is a medical condition which may result in blurred or no vision in the center of the visual field.  Early on there are often no symptoms. Over time, however, some people experience a gradual worsening of vision that may affect one or both eyes. While it…

Sight Loss

World's First Gene Therapy Operation For Sight Loss

Researchers in Oxford have carried out the world’s first gene therapy operation to tackle the root cause of age-related macular degeneration (AMD); the UK’s most common cause of sight loss. The procedure was carried out at the John Radcliffe Hospital support of the NIHR Oxford Biomedical Research Centre in a clinical trial sponsored by Gyroscope…

Blindness

Health Burden Of Glaucoma Worldwide

Glaucoma is the leading cause of irreversible blindness worldwide; accounting for 8% blindness in 2010. Glaucoma affected 64.3 million people in 2013, which will increase to 76.0 million in 2040 and further to 111.8 million in 2040. Its distribution was extremely disproportionate; with about 60% of any glaucoma and 76.7% of primary angle closure glaucoma…

Visual Processing Between The Retina And The Brain

Researchers in Munich and Tuebingen find that processing of visual stimuli occurs at the earliest waystation; on the way to the visual cortex but not all inputs are treated equally. In humans, the visual system collects up to 80 % of all the sensory data received from the environment. In order to make sense of…
