Rosy health and sickly green: color associations play robust role in reading faces

NIH, National Eye Institute (NEI)

Anyone who has ever sensed that a person is sick simply by looking at their face has experienced the wealth of information conveyed by face color. A new study by the National Eye Institute (NEI), part of the National Institutes of Health, provides evidence that the human brain’s visual system is especially sensitive to the color of faces compared to the colors of other objects or things. Study results were published today in Nature Communications.

Children’s Brains Reorganize After Epilepsy Surgery to Retain Visual Perception

NIH, National Eye Institute (NEI)

Children can keep full visual perception – the ability to process and understand visual information – after brain surgery for severe epilepsy, according to a study funded by the National Eye Institute (NEI), part of the National Institutes of Health. A new report by Carnegie Mellon University, Pittsburgh, researchers from a study of children who had undergone epilepsy surgery suggests that the lasting effects on visual perception can be minimal, even among children who lost tissue in the brain’s visual centers.

New Treatment for Severe Dry Eye Disease Promising in Early Clinical Trials

University of Illinois at Chicago

Participants in a phase I/II clinical trial of a new enzyme-based treatment for severe dry eye disease experienced reduced signs of disease and discomfort, according to a paper in Translational Vision Science and Technology.The trial compared eye drops containing a biosynthetic form of an enzyme called DNase with eye drops without the enzyme.

NIH Study Finds No Evidence That Calcium Increases Risk of AMD

NIH, National Eye Institute (NEI)

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. The study findings are published in JAMA Ophthalmology.

Imaging Method Reveals Long-Lived Patterns in Cells of the Eye

NIH, National Eye Institute (NEI)

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 to track individual cells in healthy volunteers and people with retinal disease. The new finding could provide a way to study the progression and treatment of blinding diseases that affect the RPE.

Newswise: Nitisinone Increases Melanin in People with Albinism

Nitisinone Increases Melanin in People with Albinism

NIH, National Eye Institute (NEI)

A small pilot clinical study at the National Eye Institute (NEI) suggests that the drug nitisinone increases melanin production in some people with oculocutaneous albinism type 1B (OCA-1B), a rare genetic disease that causes pale skin and hair and poor vision. Increased melanin could help protect people with the condition against the sun’s UV rays and promote the development of normal vision.

Glaucoma detection gets potential boost from virtual reality, brain-based device

NIH, National Eye Institute (NEI)

A wearable brain-based device called NGoggle that incorporates virtual reality could help improve glaucoma diagnosis and prevent vision loss. Duke University researchers funded by the National Eye Institute (NEI) have launched a clinical study testing the device in hopes that it could decrease the burden of glaucoma, a major cause of blindness in the U.S.

Faulty molecular master switch may contribute to AMD

NIH, National Eye Institute (NEI)

A signaling pathway controlled by transforming growth factor beta (TGF-beta) could be involved in the progression of age-related macular degeneration (AMD).

NIH researchers rescue photoreceptors, prevent blindness in animal models of retinal degeneration

NIH, National Eye Institute (NEI)

Using a novel patient-specific stem cell-based therapy, researchers at the National Eye Institute (NEI) prevented blindness in animal models of geographic atrophy, the advanced “dry” form of age-related macular degeneration (AMD), which is a leading cause of vision loss among people age 65 and older. The protocols established by the animal study, published January 16 in Science Translational Medicine (STM), set the stage for a first-in-human clinical trial testing the therapy in people with geographic atrophy, for which there is currently no treatment.

Researchers Design Technology That Sees Nerve Cells Fire

NIH, National Eye Institute (NEI)

Researchers at Stanford University, Palo Alto, California, have created a noninvasive technology that detects when nerve cells fire based on changes in shape. The method could be used to observe nerve activity in light-accessible parts of the body, such as the eye, which would allow physicians to quantitatively monitor visual function at the cellular level.
