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.

Researchers identify seizure-associated depolarization as cause of post-ictal symptoms

People with temporal lobe epilepsy in particular often wander around aimlessly and unconsciously after a seizure. Researchers at the University Hospital Bonn (UKB), the University of Bonn, and the German Center for Neurodegenerative Diseases (DZNE) have identified a neurobiological mechanism that could be responsible for this so-called post-ictal wandering and potentially other postictal symptoms.

Artificial intelligence detects mild depression through micro-movements in facial muscles

Depression is one of the most common mental health challenges, but its early signs are often overlooked. It is often linked to reduced facial expressivity. However, whether mild depression or subthreshold depression (StD) (a mild state of depressive symptoms that does not meet the criteria for diagnosis but is a risk factor for developing depression) is associated with changes in facial expressions remains unknown.
