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.

Study identifies early risk factors for progressive supranuclear palsy

Progressive supranuclear palsy, or PSP, is a rare brain disease that causes problems with balance, eye movements and thinking. Civil rights leader Jesse Jackson recently passed away after living with the disease for more than a decade.

AI-driven OCT imaging system enables precise wound healing assessment

No matter the size or severity, wounds on human skin are difficult to monitor while they heal. Biopsies disrupt the wound site and are too invasive for routine, repeated monitoring, and most medical imaging devices that could do the job are large, expensive and booked up with more pressing diagnostics.

New pathway explains poor response to bladder cancer immunotherapy

Researchers at the Icahn School of Medicine at Mount Sinai and the Mount Sinai Tisch Cancer Center have discovered a biological pathway that helps explain why some bladder cancers do not respond well to immunotherapy.
