A Quick Insight to the Meibomian Glands
First of all, what exactly are meibomian glands?
Named after the German physician Heinrich Meibom who discovered them back in the 17th century, Meibomian glands are oil glands located in the rim of the upper and lower eyelids where the eyelashes are.
These glands are responsible for secreting oils onto the surface of the eye that keeps the tears from evaporating too quickly. Without these oils secreted by the Meibomian glands, the eye dries out and become irritated.
Meibomian Gland Dysfunction
Changes to the amount and quality of oil that the Meibomian Glands produce can cause MGD. Multiple factors can lead to MGD, but the most common cause is the blockage and clogging of the glands.
When less and less oil reaches the eye, the tears evaporate too quickly. This is why MGD is highly associated with dry eye disease.
Like dry eyes, the risk of developing meibomian gland dysfunction increases with age. Compared to children and young adults, people aged 40 and above have a significantly higher risk of developing MGD. Aside from dry eye disease, MGD is also connected to an eyelid condition called blepharitis.
It has similar symptoms as dry eyes as well, like burning sensation, itchiness and irritation. MGD can also cause redness, inflammation and irritation in the eyelids. Early diagnosis of MGD is vital since if left untreated, it can cause permanent damage to the eyes.
Meibomian Gland Expression
Eye specialists usually perform meibomian gland expression to diagnose if the patient is suffering from MGD. Eye doctors squeeze out the oil from the eyelids to determine if there’s clogging in the glands.
Aside from being a diagnostic procedure, meibomian gland expression is also a proven effective therapy for MGD. It can reduce the symptoms and improve signs of MGD. Meibomian gland expression is one of the most common procedures for MGD where you deal directly with the clogging and blockage of the glands.
How Does It Work?
The procedure for meibomian gland expression involves applying pressure to the eyelids to express the glands and squeeze out the oils.
Eye specialists use tiny forceps or paddle-like instruments to compress the lower and upper eyelids. Mastrota paddle is a standard tool for meibomian gland expression. It is designed to squeeze out the oil from the meibomian glands effectively. The eye doctor places the Mastrota between the eye and the inner eyelid, parallel to the glands. Then, he or she uses a finger or a cotton tip to apply pressure in the outer eyelid.
Eye doctors may also apply warm compress before the expression for the smooth secretion of the hardened oils that clog the glands. A topical anesthetic like proparacaine can also be used to both eyes before the procedure.
Meibomian gland expression is also usually performed alongside other eye treatments like Intense Pulse Light (IPL) treatment and Blephasteam.
