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.

Lung tumors rewire immune cells in the bone marrow before they reach cancer sites

Lung tumors don't just evade the immune system. They reshape it at its source. Researchers from the Icahn School of Medicine at Mount Sinai and collaborators report in the September 10 online issue of Nature that tumors rewire immune cells in the bone marrow before they even reach the cancer, suggesting a new target to enhance the durability of current immunotherapy

Brain lateralization shapes the mental number line in newborn chicks

Lateralization of the brain – the tendency for the left and right hemispheres to specialize in different functions – underlies the development of a left-to-right mental number line, according to a study in newborn chicks.

Electronic nose technology aims to transform food safety

The presence of a strong, unpleasant odor in food is an indication that bacteria has contaminated the food past the point of human consumption. However, oftentimes pathogens such as salmonella and E. coli are difficult to detect.

HPV-DeepSeek shows promise for early detection of head and neck cancer

Human papilloma virus (HPV) causes around 70% of head and neck cancers in the United States, making it the most common cancer caused by the virus, with rates increasing each year.

New tool can predict where deadly brain cancer might reappear

Glioblastoma is a devastatingly effective brain cancer. Doctors can cut it out or blast it with radiation, but that only buys time. The cancer has an insidious ability to hide enough tumor cells in tissue around the tumor to allow it to return as deadly as ever.

Nicotine pouch use may be a step toward reducing more dangerous forms of tobacco

As lawmakers and public health experts debate the safety of nicotine pouches, researchers from Rutgers Health found that for now, most adults that use these products also have a history of tobacco use and may be choosing these products as a possible step toward reducing or quitting more dangerous forms of nicotine delivery.

Innovative approach advances equity in health care AI

A team of researchers at the Icahn School of Medicine at Mount Sinai has developed a new method to identify and reduce biases in datasets used to train machine-learning algorithms-addressing a critical issue that can affect diagnostic accuracy and treatment decisions.
