Tränenabflusssystems

Tränenabflusssysteme, also known as lacrimal drainage systems, are the structures within the human eye that are responsible for the drainage of tears. Tears are produced by the lacrimal glands and play a crucial role in maintaining the health and clarity of the eye. The primary function of the tränenabflusssystem is to remove excess tears, dust, and other debris from the surface of the eye, ensuring clear vision and protecting the eye from potential irritants.

The lacrimal drainage system consists of several components. Tears are initially collected in the upper and lower lacrimal sacs, which are small, sac-like structures located in the upper and lower eyelids. From these sacs, tears flow through the lacrimal ducts, which are narrow tubes that lead to the lacrimal canaliculi. The canaliculi are tiny openings that drain into the lacrimal lake, a small depression located in the medial aspect of the upper eyelid. The tears then drain into the nasolacrimal duct, which passes through the nasal bone and empties into the inferior meatus of the nasal cavity.

The lacrimal drainage system is essential for maintaining eye health and preventing infections. Dysfunction of this system can lead to various conditions, including epiphora (excessive tearing), dry eye syndrome, and conjunctivitis. In some cases, surgical interventions may be necessary to correct abnormalities in the lacrimal drainage system, such as dacryocystorhinostomy (DCR) or dacryocystectomy.

Proper maintenance of the lacrimal drainage system is important for overall eye health. Regular eye examinations can help detect any issues early, and maintaining good hygiene practices, such as gently cleaning the eyelids and avoiding rubbing the eyes, can help prevent problems related to the lacrimal drainage system.
