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.

AI algorithm proves more accurate than experts in glaucoma detection

While artificial intelligence (AI)-powered screening has been validated for diabetic retinopathy, applying the technology to glaucoma has proved more challenging because glaucoma is not one disease. A glaucoma diagnosis is based on a constellation of symptoms, diagnostic tests, and longitudinal data.

New chip restores reading ability for macular degeneration patients

A tiny wireless chip implanted in the back of the eye and a pair of high-tech glasses have partially restored vision to people with an advanced form of age-related macular degeneration. In a clinical trial led by Stanford Medicine researchers and international collaborators, 27 out of 32 participants had regained the ability to read a year after receiving the device.
