Iris

The Iris controls pupil size and consists of smooth muscle tissue controlled by the midbrain. There are different muscle bundles: pupil openers and pupil closers

Also see eyelid, cornea, lens, retina, vitreous body.

Themes

• Light morsel. Too much or too little light to see something (properly).
• Being blinded and therefore not having seen the wanted (left) or the danger (right).
• It was too dark to clearly see the wanted (left) or the danger (right), literally or metaphorically.

Difference between left and right see ring shaped organism.

CA phase

Functional increase. Adjusting brightness to see better.

Biological purpose and results

• Strengthening of smooth muscle to better regulate pupil size. This allows more or less light to enter.
• With longer running theme of insufficient light: enlargement of pupil to see better in the dark. Hypersensitive to light, sunglass wearers.
• With longer running theme of too much light: pupil reduction, night blindness.
  
  

Further symptoms

None.

PCL phase

Normalization of pupil size.

Symptoms

None, possibly distorted iris when the program runs in a part of smooth muscle tissue (Coloboma).

EC

"Cramping" iris, fluctuating pupil size.
