!Eyes – Iris & Ciliary Body
!!Anatomy
The iris is the __blind of the ((Sensory - Eyes Overview|eye))__ which surrounds the pupil. It's pigment layer collects scattered light. It is divided into two major regions:
*The stroma connects a __sphincter muscle__ (sphincter pupillae) which contracts the pupil  and a set of __dilator muscles__ (dilator pupillae) which open it. They are directed by the ((Nervous - System Overview|autonomous nervous system)): in stress the pupil widens and in relaxation it narrows. The back surface of the stroma is covered by the iris __pigment epithelium__. 
*The outer edge or root of the iris is attached to the sclera and the anterior ciliary body. The ciliary body produces __aqueous humor__ which constantly drains through the region just in front of the root of the iris, with the result that diseases of the iris often have important effects on intraocular pressure and indirectly on vision. The eye ((Sensory - Eyes - Crystalline Lens|lens)) is suspended with __zonula fibres__, and is __accomodated/adjusted__ by ((Organ Walls - Smooth Muscle Layer|ciliary muscles)). The iris and ciliary body together are known as the anterior uvea.

!!Brain
In the Brain Stem, the __primeval ring structure__ is reflected: organ tissue relays with assimilative and digestive functions from oesophagus to small intestines are situated in the right brain stem, while excretory organs from caecum to rectum are relayed in the left brain stem. Medial on both sides are the relays of mouth/pharynx, middle ears and lacrimal glands, as well as the pineal and pituitary glands and the thyroid.

!!Mind
!!!Theme
“Visual Chunk”: Capturing or avoiding light

!!!Emotions, Thoughts
__Pressure, Strain__
*I can't see that! 
*The light is hurting my eyes! 
*I was incapable of keeping my eye on it. 
*My sight was inadequate. 
*I will never forget that sight. 
*I wish I had never seen that. 
*I need to see that to catch it!

!!!META-Meaning
*Everything I need to see is within my reach, and I can let the rest pass. 
*I find it easy to look and to see. 
*I trust my eyes.

!!Organ
!!!Stress Phase Symptoms
1. Increase of tension in the affected muscles (too much or too little light). Due to that contracture, the pupil cannot adapt to the incidence of light, which leads to __myosis__ or __mydriasis__ (night-blind or overly light-sensitive).

2. Proliferation in iris pigment cells (__iris naevus__) and thickening of the stroma. Possibly incorporation of substances from medication or processes in other organs.

3. Increase of production of aquaeous humour which leads to high inner pressure and can be diagnosed as __glaucoma__.

!!!Regeneration Phase Symptoms
1. Normalization of tonus in the smooth muscles.

2. Inflammation of iris and ciliary bodyr (__iridocyclitis__) and degradation of the reinforced tissue. Possibly __angle closure glaucoma__ (Oedema in the anterior or posterior eye chamber) during regeneration phase A.
__Iris coloboma__ (gap formation) is seen after eye damage or as incomplete embryonic development.

!!!Biological Meaning
By functional increase in the stress phase, capturing or avoiding light / a visual chunk is facilitated.

!!Social
!!!Examples
*A construction worker has looked into a welding bow which blinded him temporarily. After the incident, the sphincter pupillae is very tense and doesn´t allow much light to enter the eye.
*A child has been kept in a dark and secluded place for several months. When set free, his eye muscles are not capable to adapt to the light.
*The elderly client cannot maintain her big house and garden, but she doesn't get the help she would like from her children. She dislikes to see the "decay" and develops changes in the iris. After deciding to move into a small flat, she gets uveitis and later, glaucoma is diagnosed. (Klapp)
*The patient had severely increased eye pressure caused by pressure at his workplace (he saw "the big pile of work" which he had to cope with short-termed). Some hours later the pressure has decreased - the ciliary body produced less aqueous humour. (Odum) 

!!Additional Information
!!!Constellations
__Brain Stem Constellation__ possible: perplexity, lethargy, passiveness, reduced movement. Purpose: new orientation

!!!Differential Diagnosis
__((Sensory - Eyes - Chorioid|Chorioid))__ (Brain Stem, +/-): proliferation of blood vessels or pigment layer in stress phase ("visual chunk") can cause vision and contrast impairment (involved in "macula degeneration"); Regeneration phase: chorioiditis, uveitis.

__((Sensory - Eyes - Retina|Retina))__ (Cerebral Cortex, -/+): stress (persecution by things/feelings): tunnel vision, scotoma, glaucoma; Regeneration phase: temporary retina detachment, then normalization. In chronic processes: macula degeneration.

__((Sensory - Eyes - Vitreous Body|Vitreous Body))__ (Cerebral Cortex & Medulla, -/+): stress (persecution by persons): degeneration, reduced intraocular pressure; in regeneration phase: opacity, glaucoma, increased pressure; chronic: Mouches Volantes.
