Faces, bodies, spiders, and radios: How the brain represents visual objects

June 5, 2020

Caltech researchers have combined tools from machine learning and neuroscience to discover that the brain uses a mathematical system to organize visual objects according to their principal components. The work was published June 3 in Nature.

Vision screening device improves detection of “lazy eye”

June 3, 2020

The NEI has funded development of a handheld pediatric vision scanner that easily and accurately screens for amblyopia, or “lazy eye.” The device could facilitate earlier identification of children who need vision-saving treatment.

Gene Found that Causes Eyes to Wither in Cavefish

June 2, 2020

University of Maryland-led study identified the first gene responsible for eye loss in cavefish, revealing connection to a human vascular disease.

'Time is vision' after a stroke

May 27, 2020

A person who has a stroke that causes vision loss is often told there is nothing they can do to improve or regain the vision they have lost. But research from the University of Rochester may offer hope to stroke patients in regaining vision.

Eye Injury Sets Immune Cells On Surveillance To Protect The Lens

May 26, 2020

Researchers at Thomas Jefferson University finds that the eye launches an immune response in the lens after injury. After injury to the cornea, immune cells travel from the ciliary body to the lens along fibers known as ciliary zonules.

Early visual experience drives precise alignment of cortical networks critical for binocular vision

May 18, 2020

Researchers at the Max Planck Florida Institute for Neuroscience identify three distinct cortical representations that develop independent of visual experience but undergo experience-dependent reshaping, an essential part of cortical network maturation.

Pace of eye disease over two years predicts long-term outcome

May 18, 2020

Progression along an age-related macular degeneration (AMD) severity scale over two years predicts the likelihood of developing late-stage disease five years later.

Retinal Texture Could Provide Early Biomarker Of Alzheimer’s Disease

May 14, 2020

Biomedical engineers at Duke University have devised a new imaging device capable of measuring the various layers of the retina at the back of the eye, which could be used to detect Alzheimer's disease.

New gene therapy delivery system aims for precision

May 4, 2020

In a novel approach to gene therapy, scientists funded by the National Eye Institute (NEI) report using gold nanoparticles and light to target specific cells in mouse retina.

Eyes send an unexpected signal to the brain

April 30, 2020

New research, led by Northwestern University, has found that a subset of retinal neurons sends inhibitory signals to the brain. Before, researchers believed the eye only sends excitatory signals.
