A diagram showing the location of the Gland of Zeis

The Gland of Zeis is a type of sebaceous gland that is found at the base of the eyelashes, specifically on the margin of the eyelid. Named after the German anatomist Eduard Zeis, these glands are responsible for the secretion of a type of sebum that lubricates the eyelashes and prevents them from becoming dry and brittle.

Structure

The Gland of Zeis is a small, tubular structure that is located in the dermis layer of the skin. It is connected to a hair follicle of an eyelash, and its duct opens into the follicular canal. The gland is composed of clusters of cells known as acini, which produce the sebum.

Function

The primary function of the Gland of Zeis is to produce and secrete sebum, a type of oily substance. This sebum helps to lubricate the eyelashes and prevent them from drying out. It also provides a protective barrier against the elements and potential pathogens.

Clinical significance

In some cases, the Gland of Zeis can become blocked, leading to the formation of a small, often painful lump known as a chalazion or a stye. This is typically caused by an overproduction of sebum or a buildup of dead skin cells. Treatment for a blocked Gland of Zeis typically involves warm compresses, topical antibiotics, or in severe cases, surgical removal.
