Iridology charts vary somewhat in the location and interpretation of their iris signs. Examination of Iris patterns has no clinical use in detecting problems not related to the eye. No correlation has ever been proven between patterns on specific areas of the Iris and the presence or absence of disease. In no case could the iridologists reliably differentiate well patients from disease conditions nor could they tell when the same person was ill or well by examining eye photographs. Bottom line Iridology has no diagnostic value.
Successful therapies occur either due to placebo or self limited illness.
Some practitioners of Iridology are well intended but misinformed while others may indeed by using intentional deception. Top Resources 1. Simon A and others. An evaluation of iridology. A study of the validity of iris diagnosis.
