iridology

 [ir″ĭ-dol´o-je]
the study of the iris as associated with disease.

ir·i·dol·o·gy

(ir'i-dol'ŏ-jē),
A hypothetic non-evidence-based system of medicine not based on evidence, involving examination of the iris, using a chart on which certain areas of the iris are presumed diagnostically specific for particular organs, systems, and structures.
[irido- + G. logos, study]

iridology

[ī′ridol′əjē]
Etymology: Gk, iris, rainbow, logos, science
the science that specializes in relations between disease and the shape, color, and other individual characteristics of the iris. There is considerable controversy over its validity.

iridology

Pseudomedicine
A system of pseudodiagnosis based on the belief that each body region and/or organ is represented by one of six regions on the iris; iridologists claim to diagnose imbalances in the body by studying the shape, colour(s) and qualities of the iris. Anecdotal reports imply that diseases can be identified by changes in the iris including anaemia, cardiac conditions, trauma, liver disease, adrenal dysfunction and renal stress. Interpretation of the changes seen differs according to the iridologist: while all agree that colour changes are significant, for some, whitish discolouration is believed to indicate overstimulation, while for others, these same spots indicate an accumulation of toxins (e.g., uric acid or cholesterol); all agree that clarity of the iris indicates healthiness. Once identified, defects can (in theory) be treated using vitamins, herbs, minerals and other substances.

Formal studies by the American Medical Association and the American Optometric Association have shown iridology to be ineffective as a diagnostic tool: in a well-controlled study of diagnostic accuracy of iridology, three iridologists examined photographs (without knowing the diagnosis) from the irises of 24 patients with severe and 24 with moderate renal disease, as well as 95 individuals with no known disease; the iridologists were unable to diagnose the presence or absence of renal disease with any accuracy.

iridology

Medical diagnosis by examination of the iris of the eye and the location of ‘clefts’ in areas said to represent the various parts of the body. The procedure, which is roughly analogous to REFLEXOLOGY, is rejected by orthodox ophthalmologists as having no scientific or rational basis.
