Modern Iridology Webinar

with Inger Rasmussen

Wednesday, November 18th, 2026

Traditional iridology is supported by extensive evidence and study, so it has become standardised and taught worldwide on the same principles.

Some experts (think of them as TCM masters who, just by looking at you and your posture, have already understood everything about your Qi—your vital force and its associated manifestations) need only look at your eyes for a few seconds to understand your inherited traits and possible imbalances.

Now, imagine what we can achieve with modern technologies, like super-precise microscopes, and how they can support research and advances. This is what the webinar is about. To put this into practice, imagine a large cohort of patients with the same condition, and we identify clear signs and markings in their irides (with 98% accuracy). Wouldn’t we use this to detect it before it manifests and help iridologists worldwide learn from this research?

This is what this talk is about.
