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.

Study links eyelash extensions to skin mites, eye irritation and blocked glands

A study among young women who regularly have eyelash extensions has found most have tiny mites, called Demodex folliculorum, living on their lashes. These mites can cause a painful reaction in the skin called demodicosis.

Healthy checkout ordinance linked to lower soda and candy sales

A new study found that a healthy checkout ordinance implemented in Berkeley, Calif. supermarkets, drug stores, and mass-market retailers in 2021 was linked to notable decreases in soda sales overall and small-package candy in supermarkets, but greater enforcement of such policies is essential for sustained and meaningful public health benefit.

Avoiding antibody-dependent enhancement enables dengue prevention and treatment

Dengue virus is one of the most widespread vector-borne viral pathogens in the world. Nearly 400 million dengue virus infections occur each year, resulting in approximately 20,000 deaths.

Year-round sun protection helps prevent skin cancer and aging

Sun safety is always in season. It's important to protect your skin from sun damage throughout the year, no matter what the weather.

New genetic variant linked to previously unrecognized retinal disease

An international team of researchers led by the University Hospital and University of Bonn, as well as the universities of Edinburgh, Basel and Pennsylvania, has identified a previously unrecognized form of inherited retinal degeneration caused by a specific variant in the EFEMP1 gene.

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.

Minimum waits delay patient care across England, BMJ data reveals

Nearly half of health boards in England are deliberately delaying care for patients by imposing minimum waiting times in an attempt to manage demand and control costs, reveals exclusive data published by The BMJ today.

Coffee, tea and dementia risk: Why the amount you drink could matter

A targeted perspective synthesizes epidemiological and mechanistic evidence examining how caffeine consumption during midlife may influence dementia risk later in life. The authors highlight potential roles for dose, age, CYP1A2 genotype, adenosine signaling and cultural drinking practices, while stressing that current observational evidence cannot establish causality.

How far your eyes move may change what you see

Researchers found that the distance the eye travels during a rapid gaze shift changes post-saccadic visual sensitivity by altering the spatial-frequency information carried by retinal luminance transients. Larger saccades preferentially enhanced lower-frequency, coarser visual information, while very small saccades could increase the relative visibility of finer, higher-frequency information.

Study reveals public willingness to select embryos using traits when given choices

A study of more than 2,000 people in the United States and China finds that the line between medical and non-medical traits, which underpins the rules on embryo testing in most countries, does not match the preferences of the public.

Experimental vaccine protects against Zika virus through T cells alone

Zika virus has been spreading for decades, but it first grabbed worldwide headlines in 2016. That February, with an outbreak sweeping the Americas, the World Health Organization (WHO) declared the surge in Zika-linked birth defects a "public health emergency of international concern"-a designation which lasted until that November.
