Lacrimal System Anatomy

Anatomical terminology edit on wikidata the lacrimal apparatus is the physiological system containing the orbital structures for tear production and drainage. The lacrimal fascia is surrounded by fibers of the orbicularis oculi muscle.

The lacrimal apparatus provides for the production and maintenance of the preocular tear film.

Lacrimal system anatomy. The anatomy and function of the components will also be highlighted as well as their anatomical relationships. In this section the embryology osteology nasal and paranasal sinus anatomy and secretory and excretory components of the lacrimal system are described in detail with clinical and surgical correlates. The normal function of this system is essential for the integrity of the ocular surface and the provision of a smooth refractive surface.

The superficial head of the muscle travels around the front of the sac to attach to the anterior lacrimal crest and the deep head of the muscle travels behind the sac to attach to the posterior lacrimal crest. The mechanism by which tears are formed distributed and drained will be discussed in the article below. A thorough understanding of lacrimal system anatomy is essential for the successful management of the tearing patient.
