Glaucoma and the optic nerve

Researchers identify genes and cell types that may have causal role in primary open-angle glaucoma formation

In a new study, researchers conducted a comprehensive study that uncovered key genes, biological processes and cell types that may affect the pathogenesis of primary open angle glaucoma, in intraocular pressure-dependent and independent manners.

Some ethnic groups at higher risk for retinal damage from diabetes

Researchers at Indiana University School of Optometry found that individuals are at different risks for retinal damage from diabetes, with certain ethnic groups and males being at a greater risk.

University of Houston expert warns red light myopia therapy can injure retina

A University of Houston optometry researcher is warning against the use of low-level red light (LLRL) therapy as a method to control myopia, or nearsightedness, especially in children.

Using fMRI, new vision study finds promising model for restoring cone function

Researchers have found that in dogs, fMRI can detect brain responses to daylight vision for black and white information as well as color information, and identify the area of the visual cortex that responds to stimulation of a cone-rich retinal region.

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.

Retinal imaging and genetics data used to predict future disease risk

Researchers combined retinal imaging, genetics and big data to estimate how likely a person is to develop eye and systemic diseases in the future.

Mega-analysis identifies gene variants associated with glaucoma in people of African ancestry

A new analysis focusing specifically on people of African ancestry identified three gene variants that may be contributing to this population’s susceptibility to developing and being blinded by glaucoma.

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.

Study finds AI–driven eye exams increase screening rates for youth with diabetes

A study of children and youth with diabetes concludes that diabetic eye exams using artificial intelligence (AI) increase completion rates of screenings to detect diabetic eye disease.

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.
