Meibomian glands in the lower eyelid imaged under amber light to show vasculature support and the gland structure. Meibomian gland dysfunction (MGD, also meibomitis or meibomianitis) is a chronic disease of the meibomian glands, which is commonly characterized by obstruction of the end of the duct that delivers the secretion produced by the glands (called meibum) to the eye surface, which ...
Meibomian gland dysfunction is more often seen in women and is regarded as the main cause of dry eye disease. [14] [15] Factors that contribute to meibomian gland dysfunction can include things such as a person's age and/or hormones, [16] or severe infestation of Demodex brevis mite.
Posterior blepharitis is an inflammation of the eyelids, secondary to dysfunction of the meibomian glands. Like anterior blepharitis, it is a bilateral chronic condition and may be associated with skin rosacea. [1] There is growing evidence that, in some cases, it is caused by demodex mites. [16]
The most common cause of dry eye is increased evaporation of the tear film, typically as a result of meibomian gland dysfunction (MGD). The meibomian glands are two sets of oil glands that line the upper and lower eyelids and secrete the oily outer layer of the tear film—the lipid layer. These glands often become clogged due to inflammation ...
People with dermatochalasis often also have blepharitis, a condition caused by the plugging of glands in the eye that produce lubricating fluid (meibomian glands). [2] Dermatochalasis can be severe enough that it pushes the eyelashes into the eye, causing entropion. [2] Weakness in the orbital septum may cause the herniation of the orbital fat ...
A meibography is an image of the morphology of the meibomian glands. Different technologies exist to perform a meibography in a non-invasive manner. Meibography is used in meibomian gland dysfunction diagnosis. [1]

Posterior blepharitis is usually due to meibomian gland dysfunction. Dermatologic conditions: there are multiple types of dermatological conditions that can result in madarosis dependent on the location. Atopic dermatitis is associated with allergic disorders and affects the lower eyelid.
