Dry eye study of the eye microbiome and immune system

Dry Eye Disease

Part of Eyes & vision clinical trials.

This trial looks at how changes in the eye’s normal germs (microbiome) and the immune response may relate to dry eye. It may help researchers better understand what drives symptoms and how to improve care.

Study eye bacteria in healthy and eye disease

This study compares the tiny living organisms (“ocular microbiome,” meaning eye-surface bacteria) in different eye conditions. It may help researchers understand how these eye bacteria relate to diseases and why some people develop problems with vision.
