Heat Therapy for Dry Eye Syndrome
Dry eye syndrome is a common condition that occurs for a variety of reasons. The leading cause of dry eye is meibomian gland dysfunction (MGD), which affects the essential oil layer of the eye’s tear film and causes the tears to evaporate too quickly. Mild to moderate cases of dry eye causes discomfort, while severe dry eye can result in permanent damage and scarring of the cornea.
More than 85% of patients who visit their eye doctor due to dry eye symptoms are diagnosed with meibomian gland dysfunction. MGD is chronic and the symptoms generally worsen when left untreated.
Fortunately, a certain procedure, called meibomian gland expression, uses heat to unblock glands in the eyelids to relieve the itchy, gritty feeling caused by MGD.
What Is Meibomian Gland Dysfunction (MGD)?
The meibomian glands are located along the outer edges of your upper and lower eyelids, where they produce complex oily fluid that stabilizes the tear film and slows the evaporation of your tears. This is an essential function, as tears ensure your cornea lubricated for comfortable and clear vision.
When the meibomian glands don’t function properly or are blocked, the oil layer of your tear film isn’t thick enough to keep your eyes moist. In addition to the rapid evaporation of tears, this creates greater friction between the cornea and eyelids, resulting in eye irritation.
What Is Meibomian Gland Expression?
Just like the pores in our skin, the tiny meibomian glands can be blocked with thickened oil residue. Meibomian gland expression is a procedure that unblocks the gland by squeezing out a tiny amount of oil from the glands. This also allows your eye doctor to determine how to best open the glands permanently.
The process is not only a method for diagnosing MGD, but also a therapy that can remove the blockage and reduce MGD symptoms.
How Does It Work?
Meibomian gland expression involves gently expressing and squeezing out the oils of the glands by applying pressure to the eyelids.
The eye doctor uses tiny forceps or paddle-like instruments to compress the lower and upper eyelids. The doctor may also apply a warm compress before the expression of the gland for the smooth secretion of the hardened oils that clog the glands.
Depending on the severity of your MGD, your doctor may suggest other types of heat therapies or treatment.
Other Heat Therapies for Dry Eye
Intense Pulsed Light
Intense Pulsed Light (IPL) heats the skin around the eye area and dislodges the oil build-up. This treatment targets the source directly – the blood vessels that surround the glands. Once this occurs, the glands can once again secrete the oils naturally, resuming their moisturizing effects.
LipiFlow is a device that applies warm and gentle pressure directly to the meibomian glands, liquefying the blockage. Your eye doctor will then be able to remove the blockage from the area, flushing out any dead cells, leaving your glands clear and comfortable.
The Bruder Mask
The Bruder Mask is a heated compress that sits over your eyes, almost like a large, soft beauty mask. The mask is made up of many tiny beads which, when warmed, release heat. This heat gently opens the oil glands and helps restore the oil secretion back into the eyes.
Meibomian gland expression promotes healthy secretion of oil to the eyes’ surface and provides excellent long-term results. All successful meibomian gland expression treatments decrease dry eye symptoms by increasing the glands’ quality of oil production. Usually, a single session is sufficient, but many people benefit from regular treatments.
If not treated early and properly, meibomian gland dysfunction can cause severe damage to your eyes and vision.
