Often referred to as "the windows to the soul," the eyes express joy, sadness, and fear. The iris is the most obvious feature of the external eye, with its color being a major factor in ethnic and familial identity. In fact, eye color has been the topic of many researchers' works, most notably the geneticist Gregor Mendel. In recent years, naturopathic practitioners have exhibited renewed interest in a disease-recognition method that is based on detailing characteristics of the human iris. Iridology is the study of carefully mapped sections of the iris and the assigned organ systems represented by those areas.1
Iridology, also known as iridodiagnosis, is an alternativemedicine technique that uses the colors, patterns, and various other properties of the iris to assess an individual's general health. (2) The technique of iridology is based on the belief that each organ in the human body has a corresponding region in the iris. Thus, the premise is that organ functioning can be examined simply by inspecting the iris.
Iridologists generally use cameras, flashlights, and microscopes to examine the patient's iris in order to detect tissue change, stromal irregularities, and pigment patterns. The results are then compared with an iris chart, which helps in correlating the various parts of the human body with different zones in the iris. A typical iris chart divides the iris into approximately 90 zones, each corresponding to a different part of the human body. Iridologists believe that the details reflected by the iris are generally the changes in the tissues of the corresponding body organelle. (2)
