Job Description of an Iridologist

Iridologists are alternative medical practitioners who use close examination of the iris to identify potential health concerns. Iridology is not legally defined or regulated within the United States like other healthcare professions; nevertheless, some natural medicine practitioners consider it valid. Iridologists study the eye in attempt to diagnose or identify specific diseases. Ostensibly, they practice by observing coloring, patterns and changes within the iris. They might also consult iridology maps that indicate which sections of the iris correspond to certain parts of the body.

Medical and Scientific Viewpoints

Proof remains elusive that iridology assists in such assessments. Scientific case-controlled studies regarding iridologists' abilities to determine whether individuals had kidney disease, gall bladder disease, cancer, asthma and other afflictions were published in the Journal of Alternative and Complementary Medicine, Journal of the American Medical Association and the Archives of Ophthalmology. All found a lack of efficacy in the practice: professional iridologists' abilities to identify medical problems were the same as what would be expected if guessing correctly by chance. Furthermore, studies have questioned the safety of the practice: an iridologist might incorrectly diagnose patients with disorders or may reassure them that they're healthy when in fact they are not.

Education Required

Because the field is unregulated by the government and medical community, there is no regulated body of coursework required to become an iridologist. However, prospective iridologists must become familiar with certain principles to successfully practice the discipline according to iridology standards. Course topics include eye anatomy and physiology, iridology theory, business basics and consultation practices; these may be taken using books, audio format and/or live classes. Iridology institutes and programs can be found worldwide, although accreditation can be complicated.
