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.

Severe COVID and flu infections increase risk of lung cancer

Severe COVID-19 and influenza infections prime the lungs for cancer and can accelerate the disease's development, but vaccination heads off those harmful effects, new research from UVA Health's Beirne B. Carter Center for Immunology Research and UVA Comprehensive Cancer Center indicates.

Dual sensory loss affects confidence in navigation and sound localization

According to a recent multi-institute PLOS One study led by the Multisensory Research Lab at the Wilmer Eye Institute, Johns Hopkins Medicine, time of hearing loss onset is a key determinant of patient confidence and self-reported sound localization abilities - the ability to perceive and locate objects in an environment - even in individuals who use hearing aids or who have received vision rehabilitation training.

Photoreceptor cells can recover from early stages of cell death

Photoreceptors are specialized cells in the eye that convert light energy into neural signals.

Wegovy linked to higher risk of eye stroke and vision loss

Wegovy, a GLP-1 agonist for weight loss, may carry the highest risk of 'eye stroke' (ischemic optic neuropathy) and sudden sight loss of the semaglutide drugs, finds an analysis of unintended side effect reports published in the British Journal of Ophthalmology.

Multi-agent AI systems outperform single models under heavy clinical workloads

As artificial intelligence (AI) becomes more common in health care, from managing records to assisting with medication decisions, researchers at the Icahn School of Medicine at Mount Sinai are asking an important question: How well does AI hold up when the workload gets intense at health system scale?
