Lacrimal drainage

Lacrimal drainage is the process of draining tear fluid from the eye into the nasal cavity through the lacrimal ducts. Tear fluid is a fluid that is produced in the tear glands and moisturizes the surface of the eye, protecting it from damage and infection.

Tear drainage occurs automatically due to the lacrimal system. Tear fluid accumulates in the conjunctival sac, the space between the inner surface of the eyelid and the eyeball. When the pressure in the sac becomes too high, tear fluid leaks out through the tear ducts in the nose.

However, if tear flow is obstructed or impaired, it can lead to various eye health problems. For example, excess accumulation of tear fluid in the conjunctival sac can cause irritation, redness and itching of the eyes, as well as dry mucous membranes. In addition, a lack of tear fluid can lead to eye dryness and irritation, which can impair the quality of vision.

In order to prevent these problems, it is necessary to monitor the health of the tear system and promptly consult a doctor if symptoms occur. One way to improve tear drainage is to use special eye drops and ointments that help increase tear production and improve its drainage.

Additionally, there are various treatments such as laser surgery to correct tear problems and improve the quality of life of patients. Overall, tear drainage is an important process for maintaining eye health and preventing various diseases.

Tear secretion is a normal physiological process of the human body, aimed at maintaining normal vision and moisturizing the conjunctiva of the eyes. Tears are a secretion or product produced by the lacrimal glands inside the conjunctiva. When the eye is damaged or inflamed, the tear glands may stop functioning or become less active, which can lead to watery eyes.

Tear production requires the formation of tear fluids, which dissolve hard deposits and provide lubrication and protection to the eye. Tear fluids also help the body remove toxins released through tears. The secretion of the lacrimal glands is regulated by the nervous system, including the brain and eyes. Regulatory neurons send signals to the stem lacrimal gland, which produces and releases molecules called neurolutamine. These neurotransmitters are sent to the body's clock tracking system and regulate tear production. In addition, nerve fibers connected to sympathetic nerve endings in the lacrimal bladder produce additional hormones (adrenaline, norepinephrine) that enhance the secretion of the lacrimal gland. This mechanism allows the body to adequately respond to sudden stressful situations.

When a person experiences problems with tear production, such as watery eyes or watery eyes, it can be caused by various reasons, including general depression, stress, fatigue, eye diseases, allergies, etc. Watery eyes can also occur due to a malfunction of the immune system, when the body attacks its own structures. Many people suffer from frequent colds, which can cause watery eyes and
