Iridology

Abstract
Iridology has existed for more than 100 years and has now aroused new interest in the age of alternative medicine. The conception that disorders in different organs of the body are projected in the iris by the appearance of a variety of signs and spots has repeatedly been rejected by medical science, apparently with little success. Supporters of iridology pretend that their critics have a professional unwillingness to accept unorthodox ideas and that future research will demonstrate the true value of iridology. An evaluation of the concepts of iridology and of controlled scientific reports has, however, established the following points: The basis of iridology and the different iris signs are explained by physiological variations of the normal human iris; controlled clinical trials and experiments conclusively show that iridology has no ability to detect disorders in other parts of the body; there are sufficient proofs that iridology is purely conjectural. Iridology is of no medical value and might even be a potential danger to people seeking medical care. It should be exposed as a medical fraud.
