5. Signs
The alterations produced by the iridian system in the stroma of the iris and the pupil as a consequence of disorders which occur in the organism are called signs.

In the irises they are shown by alterations in the iridian mesh, with the signs taking different shapes and by the alteration of their colour or tone, by marks or pigmentation. In the pupils by alterations in the pupil edge, their shape, miosis or mydriasis. It is supposed that the signs which appear in the pupil edge are iris filaments which penetrate the pupil space, no signs are considered to exist in the aqueous humour. Alterations which appear in the iridian stroma and in the pupil as a consequence of pigmentation alterations, trauma or physical defects and which do not reflect disorders in the organism are excluded from the present study.

Classification of the signs is carried out according to:
Their topographic area, their origin, their functional state and the phase they are in, their relation to other signs and their morphology.

• According to the topographic projection area:
- Iridian signs. These are the signs which are projected in the topographic areas in the iris.
- Pupil signs. These are the signs which are reflected by the pupils.

• According to origin and projection:
- Genetic signs. These are the signs which are projected during the first months of life. They inform of genetic predisposition to suffering certain disorders and physical constitution.
- New signs. These are the signs which are projected when a disorder occurs in the human organism.

• According to functional state and the phase they are in:
- Active signs. These are the signs which reflect a disorder which is affecting the correct functioning of the organism. This disorder produces the corresponding symptoms.
- Residual signs. These are the signs which correspond to disorders which have been completely cured. They are signs which are in regression.
- Latent sign. This is a sign which does not show a pathology.

• According to their relation to other signs:
- Associated signs. These are the signs which are projecting the same disorder. They are produced in the same topographic area and at the same time. Disorders may be projected in the iris by one sign or several signs. The latter case is what is known as associated signs.
- Complementary signs. These are the signs which project disorders which are affecting different parts or functions of the organism which do not produce any clear symptoms, or produce such subtle symptoms that they are not perceived. The information they provide is complementary to knowledge of the general state of health. M.R.I. reveals the existence of disorders which can only be detected by means of the information conveyed by the signs they project.

• According to their morphology:
They are named in accordance with the shape they take. They may be lacuna, transverse, rhombus, dots, etc. Within this classification we have defined 50 iridian signs with different variants and 15 pupil signs. This classification and definition is set out in “Study nº2” of the “M.R.I. Course”.
