Eye Health

Vision is a vital sense that significantly impacts the quality of life. This hub features numerous well-researched articles on the anatomy, physiology, and function of the human eye, as well as in-depth discussions on common and rare eye diseases, their diagnosis and treatment, and recent developments in ophthalmology. You can find information here based on evidence on a wide range of topics, from eye care and vision screening for children to more complex conditions such as glaucoma, diabetic retinopathy, and eye cancers. The collection also examines how genetics and the environment impact eye health, the effects of systemic diseases on the eyes, and the application of new technologies such as optogenetics and artificial intelligence in clinical ophthalmology.

Air Pollution and Eye Health

The eye is a delicate organ with a large and moist area exposed to the environment that makes it more susceptible to air pollution than other parts of the body.

Deafness prompts brain rewiring to enhance peripheral vision

The brains of people who are deaf from an early age re-wire to see more of what is happening in their visual periphery, new research has revealed.

Some mice showed signs of stress resilience before the stress even began

Researchers found that mice later classified as resilient showed stronger coordination between neuronal OFF-periods and slow-wave activity in the prelimbic cortex even before social stress. After social defeat, resilient mice also showed a distinct reorganization of neuronal silence during NREM sleep, linking local sleep dynamics with behavioral resilience.

Norwegian scientists harvest super donor cells to fight diverse diseases

Cells from nine "super donors" are being collected in Oslo. The aim is for these to be used to repair or replace damaged cells, tissue and organs in people suffering from conditions ranging from heart attacks to Parkinson's disease.

One brain implant could give people with paralysis a more expressive way to communicate

Researchers showed that a single high-density ECoG implant could decode attempted speech and upper-body gestures in parallel in people with severe paralysis, allowing two participants to control a personalized full-body avatar. Training the decoders on both isolated and concurrent behaviors improved performance across contexts and reduced false activations, offering proof-of-concept evidence for more expressive multimodal BCIs.

Summer program improves social skills in young autistic children

A summer intervention program for autistic children ages 4-6 with no intellectual disability significantly improved their social performance, according to a study by researchers at the Institute for Autism Research (IAR) at the University at Buffalo. It was published in Advances in Neurodevelopmental Disorders in July.

New brain computer interface restores simultaneous speech and physical gestures

A National Institutes of Health (NIH)-funded scientific team has shown that a new brain-computer interface (BCI) can allow people with vocal tract and bodily paralysis to convey both speech and upper-body gestures simultaneously.

Air pollution linked to higher risks of glaucoma and cataract

People who live in areas with higher levels of air pollution are more likely to develop glaucoma and cataract, according to a large study presented today (Monday) at the 44th Congress of the European Society of Cataract and Refractive Surgeons (ESCRS).

Smartphone imaging accurately supports remote cataract referral decisions

Researchers have found a high level of agreement between cataract referral decisions based on smartphone images reviewed remotely and those made by ophthalmologists examining patients in person at rural eye camps.

Study reveals structure of color-sensing cone cells in primates

For over 60 years, scientists have debated a basic structural question about cone photoreceptors, the cells that let vertebrates see color: are their light-sensing disk membranes closed off inside the cell, or are they open to the extracellular space? In non-mammalian species, the answer is clear - cone disk membranes typically stay continuous with the surrounding plasma membrane and are therefore open.
