The glands of Zeis service the eyelash. These glands produce an oily substance that is issued through the excretory ducts of the sebaceous lobule into the middle portion of the hair follicle. In the same area of the eyelid, near the base of the eyelashes are apocrine glands called the "glands of Moll".

Meibomian gland probing is also used on patients who experience deep clogging of the glands. Meibomian gland dysfunction may be caused by some prescription medications, notably isotretinoin. A blocked meibomian gland can cause a chalazion (or "meibomian cyst") to form in the eyelid.
Sebaceous carcinoma is a neoplastic growth of sebaceous glands. It is predominantly seen in the head and neck region given the high density of sebaceous glands in this region. The periocular region, which includes the meibomian, Zeis, and sebaceous glands of the caruncle and eyelid, is the most common site accounting for up to 75% of SGc. [6]
Along the inner margin of the tarsus are modified sebaceous glands known as tarsal glands (or meibomian glands), aligned vertically within the tarsi: 30 to 40 glands in the upper lid, and 20 to 30 in the lower lid, which secrete a lipid-rich product which helps keep the lacrimal secretions or tears from evaporating too quickly, thus keeping the ...
Moll's gland, also known as the gland of Moll or ciliary gland, is a modified apocrine sweat gland that is found on the margin of the eyelid. They are next to the base of the eyelashes, and anterior to the meibomian glands within the distal eyelid margin. These glands are relatively large and tubular-shaped.
An external hordeolum, or stye, is a purulent inflammation of infected eyelash follicles and surrounding sebaceous (Gland of Zeis) and apocrine (Moll's gland) glands of the lid margin. Trichotillomania is a disorder that urges the sufferer to pull out scalp hair, eyelashes, etc.
Hordeolum is an infection of the sebaceous glands of Zeis usually caused by Staphylococcus aureus bacteria, similar to the more common condition Acne vulgaris. It is characterized by an acute onset of symptoms and it appears similar to a red bump placed underneath the eyelid.
