Epitarsus: Anatomical feature of the cartilage of the eyelid

The epitarsus, or epitarsus (from the Greek epi-, above, and the anatomical term tarsus palpebrae, cartilage of the eyelid), is a structural feature of the eyelid that plays an important role in its functionality and protection of the eye.

The tarsus palpebrae, or eyelid cartilage, is a thin, semicircular skeletal element located in the area of ​​the upper and lower eyelids. It consists of dense fibrous tissue and contains Meibomian glands, which are responsible for producing an oily secretion necessary to lubricate the eyeball and prevent evaporation of tears.

The epitarsus is a small thickening or growth located on the inner surface of the tarsus of the palpebrae. This structure is usually a few millimeters in size and may not be visually noticeable. However, its presence is essential for the normal functioning of the eyelid and the protection of the eye.

The main function of the epitarsus is to prevent the eyelid from penetrating too deeply into the palpebral fissure when closing. During blinking and closing of the eyelid, the epitarsus serves as a kind of shock-absorbing cushion that softens shocks and prevents damage to the eye. Thanks to this structure, the eyelids fit tightly to the eye, providing effective protection against external influences such as dust, bacteria or mechanical damage.

In addition, the epitarsus contributes to the correct distribution of tear fluid over the surface of the eye. It helps distribute tears evenly when blinking, preventing excess accumulation in the corners of the eye and providing optimal moisture for the cornea.

Despite its small size and inconspicuousness, the epitarsus plays a significant role in eye health and comfort. Its presence contributes to the efficient functioning of the eyelids and prevents various problems associated with their functionality. In some pathological conditions, such as deformations of the eyelid or its internal structures, the epitarsus may be impaired, which can lead to discomfort, dry eyes and other unpleasant symptoms.

Thus, the epitarsus is an important anatomical feature of the eyelid cartilage. It provides eye protection, shock absorption during blinking and proper distribution of tear fluid. Thanks to the epitarsus, the eyelids effectively perform their functions and help maintain eye health.
