Retinal photoreceptors use dual pathways to tell brain ‘I’ve seen the light!’

Neuroscientists at Johns Hopkins Medicine have shown that intrinsically-photosensitive retinal ganglion cells use two different pathways at the same time to transmit electrical “vision” signals to the brain.

Knowing what dogs like to watch could help veterinarians assess their vision

University of Wisconsin-Madison study to support development of more sensitive ways to assess canine vision discovers what dogs most like to watch.

New technique enhances quality control of lab-grown cells for AMD treatment

NEI researchers improved a crucial step in the production of retinal pigment epithelium (RPE), a tissue they grow in the lab from patient blood cells and are testing in a clinical trial as treatment for AMD.

Researchers engineer in vivo delivery system for prime editing, partially restoring vision in mice

By adapting virus-like particles to carry the machinery for a type of gene editing called prime editing, scientists have corrected disease-causing mutations in animals and increased editing efficiency.

New research aims to develop novel therapeutic for glaucoma

Researchers at Indiana University School of Medicine are using a novel approach to hopefully develop a new therapy for glaucoma, a complex disease that eventually leads to blindness.

UH Optometry researcher receives $1.4 million to map the cornea

A team of scientists have received funding to explore new approaches to disentangle intricate nerve networks in the cornea and discover which nerve makes people blink, which creates tears and which nerve tells us our eye is in pain.

U.S. - Ireland R&D Partnership hosts workshop

About 50 participants took part in the virtual event, designed to raise awareness of the U.S.- Ireland R&D Partnership Program.

Study identifies "visual system" protein for circadian rhythm stability

Scientists have identified a protein in the visual system of mice that appears to be key for stabilizing the body’s circadian rhythms by buffering the brain’s response to light.

LSU Health discovery may open new therapeutic avenues for degenerative diseases of the brain and eye

Researchers at Louisiana State University have identified a new mechanism that protects against the excessive oxidative stress that precedes the development of neurodegenerative diseases of the brain and eye.

Cell types in the eye have ancient evolutionary origins

In a comparative analysis across animals of the many cell types in the retina, researchers concluded that most cell types have an ancient evolutionary history.
