ZONES OF IRIS

Circular division/Zones: From the pupil to the outer border of the iris the area is divided by concentric rings. Each of these divisions is called a Zone. Not only are many zones specified, but their names are very different. Peczely names three zones - a stomach, an intestine and an outer zone. Felke and Kritzer specify only two regions. Frau Eva Flink and Struck divide the iris into three large zones or six small zones. Dr. Bernard Jensen of California named 7 zones.

Immediately around the pupil is a fine dark -to-light brown border which is quite narrow, and which we designate as the Pupillary margin / Neurasthenic ring . The real objective of observation is the `edge' around the pupil. Colour changes and organic lesions of this ring indicate disturbances of the central nervous system. According to Frau Eva Flink and Struck, the iris is divided into three major, or six minor equal zones.

1 st major zone/ pupillary zone. The area from the pupillary margin upto the iris wreath is the pupillary zone On examination of the iris a change in the course of the iris fibres is noticed. This interruption in the course of the fibres , which normally includes about one-third of the iris, is called the Iris-wreath/ Autonomic nerve wreath. The first major zone, is subdivided, and includes the first and second minor zones The Ciliary Zone: The further division of the outer two-thirds of the iris is called the ciliary zone. This zone contains 2 major zones (the second and third major zones) each divided into two minor zones .

The First Major Zone contains First minor zone - stomach Second minor zone - intestines The Second Major Zone contains Third minor zone - blood and lymph vessels Fourth minor zone - muscular system organs: heart, kidneys, adrenals, pancreas and gall-bladder. The Third Major Zone contains Fifth minor zone - skeletal system Sixth minor zone – skin liver and spleen, nose, mouth, urethra, anus.

7 zones according to Bernard Jensen :

1) Stomach 2)Intestine 3)Heart, Bronchi, Pancreas , Adren , Pit.G , Pineal, Gall Bladder 4)Prostate, Uterus, Skeleton 5)Brain, Lung, Liver, Spleen, Kidneys, Thyroid etc 6)Muscles ,Motor Nerves, Lymphatic, Circulatory 7)Skin, Sensory Nerves .
