Meibomian Gland:
The Meibomian gland refers to a sebaceous gland located within the eyelids, specifically in the tarsal plate. It is responsible for producing and secreting an oily substance known as meibum, which plays a crucial role in the lubrication and protection of the ocular surface.
The Meibomian glands are vertically aligned along the upper and lower eyelids and open onto the rim of the eyelid margins. These glands consist of numerous acini or lobules, each of which contains sebaceous cells that produce meibum. The meibum secreted by these glands integrates with the tears produced by the lacrimal glands, contributing to the formation of the tear film.
The meibum produced by the Meibomian glands has several key functions. Firstly, it helps to stabilize the tear film, preventing excessive evaporation and maintaining optimal moisture levels on the ocular surface. Secondly, meibum aids in preventing tears from overflowing onto the face. Lastly, it acts as a physical barrier, protecting the eyes from potential microbial infections, environmental debris, and irritants.
Disorders of the Meibomian glands can lead to conditions such as Meibomian gland dysfunction (MGD), which is associated with symptoms such as dry eyes, discomfort, and potential damage to the ocular surface. MGD can be caused by factors such as inflammation, obstruction of the gland's openings, or changes in the composition of meibum. Effective management of MGD involves various treatment options aimed at improving the quality and function of the Meibomian glands and reducing associated symptoms.

Etymology of MEIBOMIAN GLAND
The word "Meibomian" is derived from the name of Heinrich Meibom, a German physician who first described the glands in the 17th century. Meibomian glands are located along the margin of the eyelids and secrete an oily substance that helps prevent the evaporation of tears from the surface of the eye.
