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 ...

Low-dose eye drops can manage adult myopia for 24 hours

Groundbreaking research from the University of Houston shows that a single low-dose atropine eye drop can produce daylong effects in managing myopia, or nearsightedness, which affects roughly one-third of U.S. adults. Professor ...

Seeing keratoconus earlier with light polarization and AI

Keratoconus is a progressive eye disease that weakens and thins the cornea, the clear front surface of the eye. In its early, subclinical stage, the cornea can still appear normal on routine exams. Yet this is when accurate ...

'MitoCatch' delivers healthy mitochondria to diseased cells

Scientists led by Botond Roska at the Institute of Molecular and Clinical Ophthalmology Basel (IOB) have developed MitoCatch, a system that enables targeted delivery of healthy mitochondria to specific cell types affected ...

How blind people map their surroundings using sound

Some blind people use returning echoes from their own mouth clicks to perceive external surroundings, or echolocation. New from eNeuro, Haydee Garcia Lazaro and Santani Teng, from Smith-Kettlewell Eye Research Institute, ...
