!Eyes - Lacrimal Ducts & Nasolacrimal Duct
!!Anatomy
The ((Sensory - Eyes - Lacrimal Gland|lacrimal glands)) are paired glands that secrete the aqueous layer of the tear film. They are situated in the upper outer portion of each orbit. The tear fluid contains salt, oil and proteins. It is lead via the __excretory ducts into the lacrimal sac__. It nourishes and cleans the ((Sensory - Eyes - Cornea|cornea)), being spread by the ((Sensory - Eyes - Conjunctiva|conjunctiva)) of the inner ((Sensory - Eyelids|eyelid)) when blinking.
The nasolacrimal duct carries tears __from the lacrimal sac into the nasal cavity__. Excess tears flow through nasolacrimal duct which opens in the nose. This is the reason the nose starts to run when a person is crying  or why you can sometimes taste eye drops. Like the lacrimal sac the duct is lined by stratified columnar epithelium containing mucus-secreting goblet cells (Brain Stem +/-) and is surrounded by ((Musculoskeletal - Connective Tissue|connective tissue)). The canal containing the nasolacrimal duct is called the nasolacrimal canal.

!!Mind
!!!Theme:
Visual Recognition, Attention

!!!Emotions, Thoughts:
The wish to be seen and __acknowledged__, or the wish to not be seen. 
*I want them to see and recognize me! 
*Look at me! 
*He can't look me in the eyes. 
*I can't look her in the eyes. 
*I don't want them to see me like this!

!!!META-Meaning:
I feel loved and recognized, because I love and recognize myself.

!!Organ
Sensitivity reaction according to __I__nner __S__kin/Stomach Mucosa Pattern with __hyperesthesia in stress phase__ ''(''point of discussion'' /Kora)''

!!!Stress Phase Symptoms:
Widening of the ducts by smooth muscle reaction which leads to momentary release of tear fluid and possibly __epiphora__ (wet eyes). Later in the process there may be ulcer formation in the lacrimal ducts accompanied by dragging pain (IS).

!!!Regeneration Phase Symptoms:
Swelling and inflammaion of the excretory ducts and lacrimal canal (__Canaliculitis__) which leads to congestion and dry eyes or __epiphora__, and sometimes could be diagnosed as a tumor.
In chronic processes, lacrimal stones (__dacryoliths__) can build up, or a stenosis can occur because of repair with scar tissue.

!!!Biological Meaning:
Because of the extended diametres of lacrimal ducts in stress phase, a larger amount of lacrimal fluid can be forwarded faster, in order to see clearer and also to draw attention to oneself (crying).

!!Social
!!!Examples:
*A child, after having got a little brother, feels that her parents don´t have eyes for her anymore but just for the baby. She cries because the lacrimal ducts hurt, and gets her mother's attention.
*A boy is mobbed at school and on his way home. He wishes himself to be invisible for his persecutors. Safe at home, he gets dry eyes.
*The client feels disregarded at work, since the office was changed and her desk moved. In the evenings, she suffers from dryness in the eyes.

!!Additional Information
!!!Differential Diagnosis:
__((Sensory - Eyes - Lacrimal Gland|Lacrimal gland))__ (Brain Stem +/-): Increased production of tear fluid in stress phase of "visual chunk" conflict, dry eyes after several regeneration phases in recurring processes because of functional degradation with scar tissue.
__((Sensory - Eyes - Conjunctiva|Conjunctiva))__ (Cerebral Cortex -/+): itch, pain & increased tear flow in regeneration phase after loss of visual contact.
Other possible reasons for dry eyes include:
*Staring, too little blinking (__((Sensory - Eye Muscles|eye muscles)), ((Sensory - Eyelid Muscles|eyelid muscles))__) e g due to work behind a computer screen 
*__Blepharitis__
*__Dry air__ through air conditioning
*__Low testosterone__ level (also due to medication)
*Eye __surgery__
