Neural Implant Monitors Multiple Brain Areas at Once, Provides New Neuroscience Insights

April 27, 2021

Researchers at UCSD have developed a neural implant that monitors the activity of different parts of the brain at the same time, from the surface to deep structures.

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.

Treatment not always needed to prevent vision loss in patients with elevated eye pressure

April 15, 2021

More than 20 years after the launch of a landmark clinical trial, follow-up examinations and analyses found that not all patients with elevated eye pressure need pressure-lowering treatment to prevent vision loss from glaucoma.

Citicoline protects against glaucoma without reducing fluid pressure in eye

April 14, 2021

A new study showed that ingesting the compound citicoline restored optic nerve (neural) signals between the brain and eye to near-normal levels in the study rats.

Gene therapy shows promise in treating rare eye disease in mice

April 13, 2021

A gene therapy protects eye cells in mice with a rare disorder that causes vision loss, especially when used in combination with other gene therapies, shows a study published in eLife.

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.

University of Maryland School of Medicine study identifies new mechanism that may cause blindness in older adults

April 12, 2021

Using laboratory-grown roundworms as well as human and mouse eye tissue, researchers have identified a new potential mechanism for age-related macular degeneration—the leading cause of blindness among older adults.

Computer model fosters potential improvements to ‘bionic eye’ technology

April 9, 2021

Researchers at Keck School of Medicine of USC develop signals that could bring color vision and improved clarity to prosthesis for the blind.

NEI joins call for standardization of ophthalmic imaging devices

April 8, 2021

Not all health care providers speak the same language, but the software in their clinical imaging devices can and should.
