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.

Latest Eye Health News and Research

Mapping the brain’s serotonin switch could lead to better antidepressants

In a discovery that could guide the development of next-generation antidepressants and antipsychotic medications, researchers at the Icahn School of Medicine at Mount Sinai have developed new insights into how a critical brain receptor works at the molecular level and why that matters for mental health treatments.

Novel eye-tracking metrics can help properly identify concussion-related vision disorders

In a new study led by Children's Hospital of Philadelphia (CHOP), researchers found that novel eye-tracking metrics can help properly identify concussion-related vision disorders, a common phenomenon among patients with persisting post-concussive symptoms that last more than 28 days after their initial injury.

Thalamic feedback pathway found to tune sensory perception

The cerebral cortex processes sensory information via a complex network of neural connections. How are these signals modulated to refine perception? A team from the University of Geneva (UNIGE) has identified a mechanism by which certain thalamic projections target neurons and modify their excitability.

Gut bacteria send direct signals to the brain to stop you from overeating

Researchers have discovered a novel gut-brain sensory circuit in mice where specialized colonic cells sense bacterial flagellin and rapidly suppress feeding via the vagus nerve. This "neurobiotic sense" operates independently of immune pathways, revealing a direct neural mechanism for microbiota-host communication.
