Iridology is the art and science of analysing the colour and structure of the iris of the eye to gain valuable health information.
This is not a new concept.
The Greek physician Hippocrates was known to have examined patient´s eyes for signs of illness, and Plato also noted an eye-body connection. Pictures on several thousand year old papyruses found in the temples of Luxor, have priests investigating the eyes of the pharaoh.
It has been claimed that the priests of Ancient Egypt were able to diagnose both existing disease and make a prognosis regarding the patient´s future health, as well as determining the characteristic features of a person, based on iris changes. In Tibetan medicine the eyes were considered to give information about many health problems, particularly focusing on the functioning of the liver.
Modern iridology owes its rediscovery to the Hungarian physician Dr. Ignaz von Peczely. As a boy, he tried to capture an owl in his backyard and in the struggle, the owl broke its leg. He noticed that a mark appeared in the bird´s iris at 6.00 on the same side as the broken leg, and as the leg healed, the sign changed.
He later recalled this incident as a physician when he was called upon to treat a man with a broken leg, and from here started to develop the iris chart we still use today. At the same time in history in another part of the world, the Swedish pastor, Nils Liljequist, began to observe the discoloration of his own irides due to taking certain chemicals and drugs. He too constructed iris charts similar to those of Ignaz von Peczely.
Today, we base most of our concepts of Iridology on the work of Dr Bernard Jensen, an American chiropractor, naturopath and iridologist.
This iris of the eye is connected to every organ and tissue of the body via the brain and nervous system. Hundreds of thousands of nerve filaments, blood vessels and muscle fibres in the iris mirror the changing conditions of associated body parts, by virtue of the nerve connections through the optic nerve, optic thalami and spinal cord.
Both the sympathetic and parasympathetic nervous systems are present in the iris. The nerve fibres in the iris respond to changes in the body tissues by manifesting a reflex physiology that corresponds to specific tissue changes and locations.
