Tear film biomarkers: What, when and why?

About the session

CPD ref: C-108377


The analysis of tear biomarkers has gained attention in the field of medical research and diagnostics because tears are easily accessible and can provide non-invasive insights into various health conditions. The emerging field of tear film biomarkers holds great promise for diagnostic and therapeutic advancements, potentially reshaping the landscape of precision medicine. 

This lecture is designed to dive into the world of the tear film, to understand how such a small liquid layer can tell us so much about both systemic and ocular health, and the future of biomarkers on the tear film.
