Learning how transplanted neurons fit in

October 7, 2021

As scientists move closer to testing regenerative therapies for eye disease, techniques are needed to monitor transplanted cells as they integrate with host tissues.

Living Retina Achieves Sensitivity and Efficiency Engineers Can Only Dream About

September 28, 2021

In a pair of papers on retinal structure, Duke University neurobiologists have shown that the rigors of natural selection and evolution have shaped the retinas in our eyes just as this theory of optimization would predict.

Retina ‘hardwired’ to predict path of moving objects

August 2, 2021

Neural circuits in the primate retina can generate the information needed to predict the path of a moving object before visual signals even leave the eye, UW Medicine researchers demonstrate in a new paper.

New biomarkers may detect early eye changes that can lead to diabetes-related blindness

July 26, 2021

New biomarkers found in the eyes could unlock the key to helping manage diabetic retinopathy, and perhaps even diabetes, according to new research conducted at the Indiana University School of Optometry.

NEI-funded technology promises to broaden access to retinal scanning

July 22, 2021

A National Eye Institute-funded project at Duke University has yielded a fully automated optical coherence tomography (OCT) device that does not require a trained operator and promises to broaden access to retinal imaging technology.

Scientists unravel the function of a sight-saving growth factor

June 16, 2021

Researchers at the National Eye Institute (NEI) have determined how certain short protein fragments, called peptides, can protect neuronal cells found in the light-sensing retina layer at the back of the eye.

AI Spots Individual Neurons in the Eye Better than Human Experts

May 4, 2021

A new combination of optical coherence tomography (OCT), adaptive optics and deep neural networks should enable better diagnosis and monitoring for neuron-damaging eye and brain diseases like glaucoma.

Audacious projects develop imaging technology to aid eye tissue regeneration

April 21, 2021

As regenerative therapies for blinding diseases move closer to clinical trials, the NEI's functional imaging consortium is pioneering noninvasive technologies to monitor the function of the retina’s neurons and their connections to the brain.

Micro-molded ‘ice cube tray’ scaffold is next step in returning sight to injured retinas

April 21, 2021

Researchers at the University of Wisconsin have developed a micro-molded scaffolding photoreceptor “patch” designed to be implanted under a damaged or diseased retina.

An artificial retina engineered from ancient protein heads to space

April 12, 2021

LambdaVision, the Farmington, Connecticut-based biotech firm that developed the artificial retina, is exploring optimizing production of an artificial retina in space, in a series of missions to the International Space Station.
