In addition to the classical medical history (comprehensive examination, tongue, pulse), I apply iris diagnosis.

What is iris diagnosis?

The iris is a reflection of the body and its organs. For example, changes in color and distinctive vascular patterns are indications of diseases such as inflammations and metabolic disorders, as well as their causes.

Description of the procedure

Originally, the human iris was diagnostically assessed with the naked eye or a non-distorting, fourfold magnifying glass. Later, iris diagnosticians startde to use microscopes, which is also used in every ophthalmological practice.

Assessment in iris diagnosis includes:

  • The pupil and the pupil rim
  • The iris
  • The conjunctiva with its vessels
  • The eyelids, lid margins, and eyelashes

However, the most important part remains the iris. To assess it, color, density, and structure must be considered. This provides insights for the naturopath regarding:

  • The constitution (overall body condition)
  • The location of illness and susceptibility to disease
  • The individual reaction pattern of the patient
  • The energy balance of the individual
  • The metabolic situation
  • The pathological connections and the causative conditions of the individual systems among themselves


Since ancient times, including the Hippocratic physicians, and notable authors from the Middle Ages like Meyens and Hildegard von Bingen, the eye has been included in diagnosis. Iris diagnosis can be traced back to the Hungarian naturopath and physician Ignaz von Peczely. His first publication, “Instructions for the Study of Diagnosis from the Eyes,” dates back to 1880/81.

German naturopaths, in particular, have embraced this method and have brought it to a high level of knowledge and understanding over the following decades up to our time. Figures like Magdalene Madaus, Theodor Kriege, Rudolf Schnabel, Josef Angerer, and many others have contributed. In the 1950s, iris diagnosis found confirmation in clinical trials conducted by Prof. Volhard, Josef Deck, and Dr. Vida.
