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 ...

Cataract surgery continues to improve across Europe

A total of 363,039 cataract surgeries performed in 12 European countries in 2024 were recorded in the European Registry of Quality Outcomes for Cataract and Refractive Surgery (EUREQUO), according to the latest figures presented ...

New research reveals underlying mechanisms of eye inflammation

A new study published in The American Journal of Pathology provides new evidence that immune cells enter the retina via the body's standard pathway, identifying PECAM as the gatekeeper and neutrophils as proresolving mediators. ...

How HIV affects the eyes of aging adults

Older adults with well-controlled HIV may have a higher prevalence of certain eye conditions, particularly dry eye, compared with similar adults without HIV, according to a new study led by a University of Colorado Anschutz ...

Boosting cell cleanup process may protect against glaucoma

Glaucoma is a neurodegenerative eye disease defined by the progressive death of nerve cells in the retina called retinal ganglion cells (RGCs) and damage to the optic nerve. It doesn't have many warning signs, so significant ...
