Iris signs, from which a disease state can be diagnosed, are differentiated
(a) By their colour
(b) By their shape
‘How do the Iris-signs Originate?’ It was stated there that white, dark and black signs can appear:
1. White signs are signs of inflammation or over-stimulation. The whiter the signs, the more acute, inflammatory and painful is the condition of the affected organ. If the condition becomes chronic, then the originally white sign changes to blue-white, dirty-white, yellow or even brown.
The white iris signs show only in blue and grey irides as so brightly white. In brown eyes, the acute state shows only as a lightening of the brown iris tissues, which are then brighter than the background shade, but never quite white.
2. Dark iris signs are signs of under-stimulation, diminished function, and enervation. The iris shows in the appropriate region—grey to dark grey, but yet not black. These signs are always to be seen where the superficial surface layer of the iris has receded to expose the second
layer—vascular layer (= the lacunae and dark wispy signs).
The dark iris-signs denote a chronic disease state of the tissues as suggested above in referring to the yellow to brown signs. The difference between these two groups is to be found in the cause of the actual disease conditions. Above are signs resulting from the deposition of toxic wastes and residues in the tissues. They are indications of a state of tissue which has been described by N. Krack in Erfahrungsheilkunde 5—1961 as follows :
These signs are symptoms of incomplete products of intermediate metabolism which infiltrate into the interstitial connective tissue and there induce degenerative processes, indurations and loss of fluid. This process is progressive, attacks always the connective tissues, and can even encroach upon vascular and nerve fibres.
As against the signs just described, which originate from an excess in the tissues, and which become visible in the iris as deposits. Above: dark iris-signs indicating over-relaxed tissues with tendency to tissue destruction and consequent atrophy.
3. Black iris signs indicate loss of substance. They originate from the destruction of the second layer of the iris, which thus allows the third pigment layer to become exposed.
4. Coloured signs in the iris—also called toxin-flecks—can appear as yellowish-red, rust-red, brown, black-brown, or in all other shades. They lie mainly in the deeper iris-layers. These foreign colourings will be explained later on in this book, but it may here be noted that Dr. Schnabel in his book Iridoskopie has written fully on these different forms and colours. Angerer also treats these indications fully in his work, Handbuch der Augendiagnostik.
