Lacrimal sac: anatomy and function

The lacrimal sac, also known as the saccus lacrimalis, is an important structure in human anatomy associated with the process of lacrimal secretion. It is located inside the orbit of the eye and is part of the tear system, which plays a key role in maintaining eye health and protection.

The anatomy of the lacrimal sac includes a cavity surrounded by tissue structures. This sac has the shape of a small pouch and is located between the inner canthus and the nasal cavity. It has an opening known as the lacrimal punctum, which connects to the lacrimal ducts and then drains tear fluid into the nasal space.

The main function of the lacrimal sac is to collect tear fluid, which is produced by the lacrimal glands. When tears form on the surface of the eye, they flow down the palpebral fissure and enter the lacrimal sac through the lacrimal punctal separator. The lacrimal sac then contracts and carries the tears into the lacrimal ducts, which direct them into the nasal cavity. This process removes excess tear fluid and maintains constant eye moisture.

However, the lacrimal sac can also become subject to various diseases and disorders that can affect its function. Some of the common problems associated with the lacrimal sac include inflammation (dacryocystitis), blocked tear ducts, or defects in the anatomical structure. These conditions can cause unpleasant symptoms such as constant tearing, swelling in the lacrimal sac, and increased sensitivity to touch.

Diagnosis and treatment of lacrimal sac problems are usually performed by ophthalmologists or tear specialists. Depending on the diagnosis, various treatment options may be used, including conservative approaches, antibiotics, lacrimal sac massage, or even surgery.

In conclusion, the lacrimal sac is an important anatomical structure required for the proper functioning of the lacrimal system. It plays a key role in removing excess tear fluid and maintaining eye health. Understanding its anatomy and function helps evaluate and treat problems associated with this area of ​​the body and ensures optimal eye health.
