Combating intractable blindness with 3D bio-printed retina

Retinal vein occlusion (RVO) is one of the leading causes of vision loss worldwide, often triggered by chronic diseases such as hypertension and diabetes. Similar to a blocked water pipe causing backflow and pressure buildup, ...

Eye scans reveal clues to aging and heart disease risk, study finds

The tiny blood vessels in your eyes might hold the key to predicting a person's risk of developing heart disease and how fast they're biologically aging, according to researchers at McMaster University and Population Health ...

Diabetes

Early trigger of diabetic eye disease identified

A team led by UCL scientists has identified a key protein that triggers diabetic retinopathy—a condition caused by high blood sugar damaging the retina's blood vessels and a leading cause of sight loss among working-age ...

Risk of eye disease increases during menopause transition

Many symptoms, such as hot flashes and vaginal dryness, are commonly associated with the menopause transition. One of the lesser-known symptoms that worsens in midlife is dry eyes. A new study suggests that postmenopausal ...

Patient wealth is associated with quality of glaucoma care

Patients with newly diagnosed glaucoma who have less wealth or reside in rural communities are less likely to receive standard glaucoma care compared to wealthier patients, according to a recent multi-institutional study ...

Ophthalmology

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. ...

Neuroscience

Understanding the minutiae of seeing in 3D

So much has to go right as our visual systems develop. One of them is that many thousands of retinal ganglion cells (RGCs) have to relay signals through the eye's optic nerve via delicate projections, or axons, to precise ...

Aging eyesight issues and treatment

Diminishing eyesight is a common issue that occurs with age. While often unavoidable, routine eye checks are crucial.

Ophthalmology

A new device for early diagnosis of degenerative eye disorders

Researchers at an EPFL lab have developed an ophthalmological device that can be used to diagnose some degenerative eye disorders long before the onset of the first symptoms. In early clinical trials, the prototype was shown ...

New app brings virtual eye care to Bangladesh

A brother-sister duo's startup has partnered with one of the largest eye hospitals in Bangladesh in an effort to make trips to the eye doctor completely virtual.

Researchers home in on a new cause of Stargardt disease

Using a new stem-cell based model made from skin cells, scientists found the first direct evidence that Stargardt-related ABCA4 gene mutations affect a layer of cells in the eye called the retinal pigment epithelium (RPE). ...

Ophthalmologists underrepresented in Google searches

In most U.S. counties, a Google search of the phrase "eye doctor near me" may underrepresent ophthalmologists, according to a study published online Oct. 20 in JAMA Ophthalmology.

Neuroscience

Neuroscientists find more naturalistic ways to study vision

For years, neuroscience experiments have depended on carefully controlled conditions. Mice run in place on tiny treadmills, rather than freely scurrying. Or they're meticulously trained to do easy-to-measure tasks that don't ...

3D map reveals DNA organization within human retina cells

National Eye Institute researchers mapped the organization of human retinal cell chromatin, the fibers that package 3 billion nucleotide-long DNA molecules into compact structures that fit into chromosomes within each cell's ...
