Theory and Philosophy and iridology


Every science remains in significance on a set of theoretical hypotheses that form its foundation and philosophy. It represents the particular context of theories, observations, experiments and tentative assumptions. Those that have extensively investigated Iridology believe its major hypotheses have already been verified by experience and by comparison with other diagnostic methods.

According to Dr. Bernard Jensen(USA), the Central Hypotheses of Iridology are:

(1) The iris reveals, through changes in pigment and structure, abnormal conditions of tissue in the human body; (2) The anterior of the iris reflexly corresponds in the systematic organization of its topography to the major tissue structures the body. For example, each organ, gland and tissue is represented in a specific location in the left or right iris, or both.

*** The documentation in support of these two central hypotheses is established on the work of hundreds of primary health care professionals that have used Iridology successfully as a diagnostic aid with thousands of patients in the past 100 years. The observations and research of iridologist have been published in many books and professional journals. The accuracy and reliability of iris signs as reflex indications of tissue pathology in the body have been confirmed in many thousands of instances by: laboratory tests, X-rays, and other commonly accepted diagnostic approaches.

(3) Organs and tissues on the left half of the body are reflexly represented in the left iris, while those of the right half of the body are represented in the right iris. Organs and tissues lying along the centerline of the body, the sagittal plane, appear in both irides, as do bilateral organs.

*** Again, this hypothesis is based upon the findings and empirical observations of hundreds of Iridologists. The research of Walter Lang (Die anatomischen und physiologischen Grunglagen Der Augendiagnostik) proposes a set of neural pathways that would account for the physiological eye changes associated with both disease states and abnormal tissue conditions. Lang indicates that afferent autonomic nerve impulses from the various organs and tissues of the body reach the anterior thalamic nuclei of the diencephalon. It therefor acts as a “file cabinet” or storage area on all anatomical conditions. Lang further suggests that this information is transmitted to the hypothalamus, which functions as a central relay and control station of the brain. Nerve impulses from the hypothalamus follow pathways via the oculomotor nucleus and the Edinger-Westphal nucleus to the muscles, stroma and blood vessels of the irides. Where they’re assumed to stimulate topographical tissue changes, corresponding to specific organ and tissue changes elsewhere in the body. Lang shows that areas of the iris can be differentiated to correspond to the various organs and tissued by definition that a single iris nerve fiber (over 28,000) controls only 5 to 10 muscle cells as compared to 200 – 300 muscle cells in the extremities. This means that changes reflexed to the iris are highly specific to certain zones. However the neural system organization is the same in all human beings, the same tissue areas of the body will always reflex to the same areas of the irides.

Hypothesis #4

The anterior iris, including the anterior epithelium, the stroma, the muscle layer, the pupillary margin, the autonomic nerve wreath (collarette), and the scleral-iris margin undergo specific changes corresponding to pathological changes in specific organs and tissues in the body.

*** Again, this hypothesis is based upon findings and empirical observations of hundreds of Iridologists. Iridologists have distinguished that the iris changes due to pathological deterioration of body tissue. This shows as a whiteness (acute) in the iris fibers, then an increasing darkness (sub-acute -> chronic -> degenerative) and the depth of iris lesions. In the past, Iridologists have also stated that they have witnessed changes due to reversal pathology (emergence of healing lines.) in the same iris lesions after successful treatment. In many cases these findings are confirmed with other commonly accepted diagnostic procedures. It must be emphasized that the pathological condition must be adequately severe to be classified by the standards of western medicine as the classification standards of Iridology are different. The various laboratory tests that are being used to determine the presence or absence of disease are not totally efficient in the assessment of subclinical conditions. Acute and sub-acute stages of tissue inflammation can commonly be detected long before other diagnostic methods are capable of finding any health problems with the patient. In a similar manner, when a patient is declared “well” by the standards of Western medicine, Iridology frequently shows a subacute condition persisting in the individual.

Authors Note: The iris is comprised of a genetically based cryptic leaf that is genotypic and does not change (No valid Proof exists) therefor you will only see changes in pigments, transversals and in the borders of certain lacunae. There are examples of Iris changes in certain Iridology books such as Jensen II and Deck books although the Jensen study is questionable due to photographic techniques used. The Deck book shows a very good example of pigment change over a period of 10 years. In most cases, one will mainly find the iris pigment(s) to become more clear after treatment or cleansing of the body. Most recently,  macro 3D imaging is now being used to show changes in the iris although these techniques need more scientific peer review. Iris photography is very difficult because the least amount of light or change in environment can change pupil size thus give the effect of change in the iris.

German medical researcher, Walter Lang, has demonstrated that the autonomic nerve fibers from virtually every gland, organ and tissue of the body extend to the thalamus and hypothalamus which monitor and respond to changes of condition in all anatomical structures. These changes of state, Lang suggests, are relayed from the thalamus and hypothalamus through the ophthalmic branch of the trigeminal ganglion to the motorneurons of the iris muscle structure. Changes in the impulses conducted by these motorneurons may be responsible for the changes in the muscle structure of the iris, leading to the gradual separation of iris fibers in the stroma and consequent appearance of the lesions and other markings familiar to iridologist. Lang also points out that the organization of the human nervous system is genotypic, and further postulates that innervation to the iris reliably represents is also genotypic, which accounts to the fact that the iris reliable represents the same organs, glands, and other anatomical subdivisions of the body in precisely the same locations in the irides of all individuals.

Hypothesis #5

Inherent weaknesses, inherent strengths and the degree of nervous system sensitivity are shown in the iris, respectively, by the crypts and separations in the trabeculae; by closely knit trabeculae; and by parallel, curved cramp rings concentric with outer perimeter of the iris, all located in the ciliary zone outside the autonomic nerve wreath.

*** Scientific research has demonstrated that the posterior pigment epithelium and dilator muscle of the irides are embrylogically derived from neurectoderm, the tissue from which the central nervous system (brain and spinal chord) are also derived. Iridologist find that it is this similarity that reflects in the iris the genetic inheritance of the individual. It is assumed that the specific configuration and development of the dilator muscle somehow determine the radial arrangement and spacing of the vascular arcades (trabeculae) in the stroma above it. The fact that crypts and separated trabeculae represent inherent weaknesses in no way conflicts with the fact that the same structures allow aqueous humor to circulate through the irides
