Involuntary eye movements could be targeted by restoring retinal dopamine, mouse experiments suggest

Researchers have found a possible way to stop abnormal signals in the retina that are linked to involuntary eye movements (nystagmus). In experiments on mouse retinas in the lab, restoring dopamine signaling stopped these ...

Scientists outline blueprint for next-generation wearable eye health sensors

Dr. Yangzhi Zhu of the Terasaki Institute for Biomedical Innovation (TIBI), with collaborators at UC San Diego and USC, published a Nature Sensors perspective on what it will take to turn tear-based wearable sensors into ...

Statins may protect people from developing glaucoma

Taking statins is linked to a lower risk of developing glaucoma and a reduced chance of it getting worse, suggest the findings of research published online in the British Journal of Ophthalmology.

What your eyes could reveal about your heart health

More than 2,000 years ago, the Greek mathematician Euclid began his treatise "Optics" with an assumption that now sounds peculiar: visual rays traveled out from the eye toward the objects we see.

Decadelong study finds smoking worsens sickle cell retinopathy

Sickle cell retinopathy (SCR), a common, potentially blinding eye condition found among some people with sickle cell disease, is caused by misshapen blood cells blocking blood vessels in the light-sensing retina. In a 10-year ...

How a membrane lipid tunes the eye's response to light

Weill Cornell Medicine investigators have determined how a molecule within cells can help tune the eyes' sensitivity to light. The study identified the molecule's binding site on a protein in retinal cells, which should enable ...

New imaging system maps retinal oxygen in unprecedented detail

The retina consumes oxygen at one of the highest rates of any tissue in the body, and disruptions in its oxygen supply are linked to blinding diseases such as glaucoma, age-related macular degeneration, and diabetic retinopathy. ...

Obesity genes tied to kidney, eye and nerve damage in diabetes

A large genome-wide analysis reports that common obesity traits share, and in some cases drive, risk for diabetic kidney disease, diabetic retinopathy, and diabetic neuropathy. The study maps shared DNA signals, tests causal ...

Bringing eye images into focus with AI

Researchers at the University of Waterloo have developed a better way to enhance the clarity and detail of eye images used to diagnose disease by teaching artificial intelligence (AI) software the science behind the imaging ...

Opticians may slash wait times, curb blindness risk

Qualified local optometrists can manage certain eye care conditions rather than those based at hospitals, significantly reducing patient waiting times and lowering costs for the NHS, a new study finds.
