!Eyelid Muscles
!!Anatomy
The eyelid is opened and closed by two types of muscles:  While the __levator palpebrae__ (lifts the eyelid) and the __orbicularis oculi__ (closes the eyelid) are ((Musculoskeletal - Skeletal Muscles|striated)) and voluntary,  there are unstriated fibers, the __tarsal muscles__, which are ((Organ Walls - Smooth Muscle Layer|smooth muscles)) and operate involuntary to widen the palpebral aperture.

The protective __eye-closure reflex__ can be triggered by touch of the cornea, or by bright light. The sensory input is relayed via the brain stem to the facial nerve (cranial nerve VII) that promotes eyelid closure.

2. __Cerebral Cortex__ (-/+) motor cortex eye area for ((Nervous - Motoric Innervation|innervation of voluntary striated muscles))

3. __Midbrain__ (+/-) posterior central for involuntary innervation (((Organ Walls - Smooth Muscle Layer|smooth muscle)) pattern)

!!!Theme:
1. (CM) Visual overwhelm, strain

2. (CC) Not being able to avoid visual stress

3. (MB) Protection of the eye and from visual triggers

!!!Emotions, Thoughts:
__Overwhelm, remorse, fear__
*I wish I had closed my eyes.
*I wish I hadn´t witnessed it. 
*I saw it but I couldn´t help. 
*I couldn´t keep my eyes open.

!!!META-Meaning:
*Now, I can decide what to look at. 
*I do not need to see everything. 
*I forgive myself for seeing/not seeing that.

!!Organ
!!!Stress Phase Symptoms:
1., 2. Paralysis of M. orbicularis oculi or M. levator palpebrae, hanging eyelid (__ectropium__ or __ptosis__). The muscles weaken gradually with decreased trophic.
3. (MB): Increased tonus in the tarsal fibres, thereby insufficient lid closure (__lagophthalmus__).

!!!Regeneration Phase Symptoms:
1., 2. Returning innervation leads to eyelid flutter (__tremor__). Later, strengthening of the muscle can lead to muscular hypertension and rigidity, especially in a chronic process. A chronically contracted ring muscle creates a lid turned inward (__entropium__).
3. (MB): Tonus normalization

!!!Healing Peak
Eyelid flutter (__tremor palpebrae__), spasm in orbicularis oculi muscle (__blepharospasm__)

!!!Biological Meaning:
1., 2. Strengthening of the function and awareness of the META-meaning by regeneration.
3. (MB): Forced application of the function needed (attention) during stress phase.

!!Social
!!!Examples:
*A woman has witnessed her brother die in an accident, as well as other scareful events. After the birth of her son, she develops ptosis and blepharospasm in a chronical process by environmental triggers. (Klapp)
*A truck driver fell asleep at the wheel which lead to an accident. He feels guilty that he couldn´t keep his eyes open, or take a rest when due. Afterwards, auditory triggers startle him to open his eys widely.

!!Additional Information
The skin and muscles of the eyelid are innervated by cranial nerves, which have fibres from brain stem, cerebral medulla and cortex (with their emotional representations connected). The tarsal muscle fibers are innervated by the autonomous nervous system.

!!!Constellations:
__Megalomania__ (Cerebral Cortex relays active in both hemispheres): Visual-attention-Megalomania: "I see everything - nothing can be hidden from me!" 

!!!Differential Diagnosis:
Increased sensitivity to light through processes in __((Sensory - Eyes - Iris|Iris)), ((Sensory - Eyes - Retina|Retina)) or ((Sensory - Eyes - Chorioid|Chorioid))__ influence the need for protection and closure of the eyelids.
__((Nervous - Facial Nerve|Facial nerve))__ (Cranial nerve VII with fibres from Brain Stem, Cerebral Medulla and Cortex) in stress phase (social devaluation fear) or when damaged: paralysis, facial paresis, lagophthalmus (insufficient lid closure)
