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.

Rethinking Mendelian assumptions in inherited retinal degenerations

A new study challenges what's long been assumed about genetic variants thought to always cause inherited blindness.

Early identification of nutrition risk in ICU patients using artificial intelligence

A new study by researchers at the Icahn School of Medicine at Mount Sinai suggests that artificial intelligence (AI) could help predict which critically ill patients on ventilators are at risk of underfeeding,

Homer1 gene plays a critical role in shaping attention

Attention disorders such as ADHD involve a breakdown in our ability to separate signal from noise. The brain is constantly bombarded with information, and focus depends on its ability to filter out distractions and detect what matters.

New tear gland organoids shed light on the biology of dry eye disease

An estimated 5-15% of people have problems with dry eyes, with symptoms including eye redness, stinging, or burning sensation, and eye fatigue. Dry eye disease (DED) occurs when the eyes' tear glands produce insufficient or poor-quality tears which can be due to allergy or autoimmune disease, hormonal changes, aging, etc.

Hotter days and nights are already stealing sleep across the U.S.

Rising nighttime and daytime temperatures are associated with reduced sleep duration, poorer sleep continuity, delayed sleep onset, and altered sleep stages in a large U.S. cohort tracked with wearable devices. Vulnerability is greatest among adults aged 40–50 years, females, people with lower socioeconomic status, chronic conditions, and those living in marine climate zones, with climate change projected to further magnify sleep loss.
