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 ...

Smart eye patch uses fluorescence to monitor eye health

A research team has used multi-emission metal organic framework hydrogel (Eu-Dy MOF gel) to construct a noninvasive wearable eye patch fluorescence sensor, combined with the color recognition function of a smartphone to analyze ...

'Eye-on-a-chip' reveals trigger for steroid-induced glaucoma

The eye, like most organs, has an intricate plumbing system. Pressure builds when drainage is impaired, and this condition—glaucoma—can cause irreversible vision loss. Certain popular anti-inflammatory eye medications that ...

Uniquely shaped microstent developed to combat glaucoma

A team of researchers at the University of Oxford have unveiled a pioneering "microstent" which could revolutionize treatment for glaucoma, a common but debilitating condition. The study has been published in The Innovation.

An alternative to LASIK—without the lasers

Millions of Americans have altered vision, ranging from blurriness to blindness. But not everyone wants to wear prescription glasses or contact lenses. Accordingly, hundreds of thousands of people undergo corrective eye surgery ...
