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.

Turning back the clock on a severe vision disorder

March 31, 2021

Scientists at the University of Pennsylvania School of Veterinary Medicine report findings of a gene therapy to treat a severe form of Leber congenital amaurosis, caused by mutations in the NPHP5 gene.

Preventive treatment reduces diabetic retinopathy complications

March 30, 2021

Early treatment with anti-VEGF injections slowed diabetic retinopathy in a clinical study from the DRCR Retina Network (DRCR.net). However, two years into the four-year study its effect on vision was similar to standard treatment.

New genetic links found to rare eye disease, opening the door to better diagnostics and potential treatments

March 25, 2021

NEI-funded research at Scripps Research Institute has turned up more than a dozen gene variants linked to MacTel, a rare eye disease. The variants are likely causing the condition to develop and worsen for a significant share of patients.

Research points to new hope for treatment-resistant AMD

February 26, 2021

The latest research from the John A. Moran Eye Center reveals how an oxidized form of cholesterol can change choroidal endothelial cells into cells that become scars and may wreak havoc in the eyes of age-related macular degeneration (AMD) patients.
