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.

Latest Eye Health News and Research

Internet-controlled brain implant enables remote neural stimulation and drug delivery

A researcher in Chicago remotely controls a miniaturized brain implant in Daejeon, Korea - over the internet. Korean researchers have developed a wireless device that can deliver drugs and light to precisely modulate targeted neurons from anywhere in the world.

New retina model reveals how CLN3-Batten disease damages vision

Researchers have developed a new way to study CLN3-Batten disease, a rare, inherited condition that causes early vision loss in children followed by progressive neurological decline.

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.

Vagus nerve stimulation may enhance long-term motor learning

Do you ever feel like sometimes you can master a new dance step almost immediately, while other times you struggle to nail it despite repeated practice? This might be due to skill or effort, but also to something less obvious: whether the brain is in a state that allows learning to take hold.

New molecular pathway explains why eye pressure rises at night

Glaucoma is an eye disease that causes progressive damage to the optic nerve, leading to loss of sight. One major risk factor is an increase in intraocular pressure (IOP), or the pressure inside the eye.

Loneliness can reprogram the brain to increase alcohol use

Loneliness can reprogram the brain in ways that push alcohol consumption, reports a new preclinical study led by Northwestern University and the Salk Institute for Biological Studies.

Type 2 diabetes mechanisms differ significantly based on patient BMI

Research published today in Diabetologia by Amsterdam UMC and the University of Ghana reveals that type 2 diabetes manifests in two fundamentally different ways depending on a patient's body mass index (BMI).

Wake-activated brain circuits reveal what drives the urge to sleep

Researchers identified wake-activated neurons in the median raphe and anterior medial preoptic area that track sleep pressure and help regulate when and how deeply mice sleep. Manipulating these circuits altered NREM sleep, sleep-pressure accumulation, and rebound sleep, revealing key neural mechanisms underlying mammalian sleep homeostasis.

Infants' sense of agency develops through culture-specific caregiver interactions

A baby sits on the floor and reaches toward a red ball on a floor and grunts. The mother responds, "Do you see the ball?" She picks it up and holds it in front of baby and says, "Do you want to hold the ball?" The baby shrieks in excitement as the mother hands the ball to the baby.

Paying attention to your body may change how an acute skin inflammation unfolds

Voluntary attention to inflammation-related bodily sensations reduced the magnitude of histamine-induced skin inflammation and promoted faster resolution compared with distraction in healthy adults. The findings point to complementary sensory-dependent and top-down autonomic pathways, although the precise neural and immune mechanisms remain unresolved.

Improved indoor lighting may prevent nearsightedness in children

Research has already shown that the more time children spend playing with screens indoors instead of playing outdoors, the more likely they are to develop myopia.

AI-based "tissue clocks" measure the biological age of human organs

AI-based "tissue clocks" can estimate the biological age of human organs from histological images, researchers at the CeMM Research Center for Molecular Medicine of the Austrian Academy of Sciences and the Ludwig Boltzmann Institute for Network Medicine (LBI-NetMed) at the University of Vienna showed.

Studies link traumatic brain injury to high mortality in Pakistan

Traumatic brain injury (TBI) in Pakistan is associated with a high risk of death and disability long after the initial injury, even in mild to moderate cases, according to two new studies in JAMA Network Open led by Weill Cornell Medicine researchers.
