There is no truth to these claims, as emphasized by the following test of iridology. In 1979, Bernard Jensen and two other practitioners of iridology were given 143 photographs of irises of patient’s eyes to view and determine which individuals had kidney impairment. (48 had a diagnosis of kidney disease as revealed by standard blood tests; the rest had no kidney disorder.) These iridologists were not able to separate the diseased from the normal. One iridologist had picked out 88 % of normal patients as having kidney disease; another examiner found that 74% percent of those patients that had severe kidney disease were identified as normal. This test was reported in the Journal of American Medical Association, 242, 1385-1387, 1979.
The British Medical Journal 297:1578-1581, 1988, carried an article of a test given to five leading Dutch iridologists. They received a stereo color slide of the right iris of 78 people, half of whom had a diagnosis of gallbladder disease, and the other half were free of any disorder. The five practitioners were not able to differentiate the diseased from the normal, and were not able to agree among themselves as to who were diseased or not. This typifies the results of many tests given to iridologists.
Another problem that exists in iridology is that there are no standards in the charts used to represent the eye, from which the diagnosis of the health condition of the person being examined is made. The following quote presents this problem.
For example, there are some twenty different iridology charts that a practitioner may choose from in his practice.
Does iridology have an astrological basis for existence? Does it have its base in the “universal energy” concept? Like much of New Age medicine, iridology makes use of the concept of mystical energy. In fact, the pupil of the eye is held to be a repository of sorts for the body’s energy, according to many iridologists.
Most iridologists agree that the integrity of the body’s energy is reflected by the quality of energy in this (pupil) hub, or core.
As to astrology, iridologist Brint sums it up this way.
From an Eastern point of view, the eye may be viewed as a Mandala… The Mandala links the microcosm and the macrocosm… Through the Mandala man may be projected into the universe and the universe into man… In iridology, the macrocosm and the microcosm are linked in our eyes… Iridology may be summed up as the observation of the change that arises from the interplay of various levels of consciousness and results in one’s unique evolution into greater (occult) truth and light.
