The eyelid margin is the thin strip of skin on the very edge of your upper and lower eyelids. It is the area where your eyelashes grow. This small part of your eyelid plays a large role in protecting your eye and keeping it comfortable and healthy.
read more about eyelid margin ...The eyelid margin has several important parts. It is home to the follicles where your eyelashes grow from. It also contains the tiny openings of the meibomian glands. These glands produce an oil that is a necessary part of your tears. The margin is the meeting point between the skin on the outside of your eyelid and the moist conjunctiva on the inside.
Several common eye problems start at the eyelid margin. Blepharitis is an inflammation that makes the margins red, itchy, and swollen. A stye is a painful, pimple-like bump caused by an infected eyelash follicle. If the meibomian glands get clogged, it can lead to a condition called meibomian gland dysfunction (MGD), a leading cause of dry eye.
Good hygiene is the best way to care for your eyelid margins. Always remove eye makeup before sleeping and gently clean the area. A warm compress held over closed eyes for a few minutes can also help keep the oil glands from getting clogged. Try to avoid rubbing your eyes, which can cause irritation.
The most critical structures located on the eyelid margin are the Meibomian glands. You have about 25 to 40 of these pores on the upper lid and 20 to 30 on the lower lid. They secrete the lipid (oil) layer of the tear film. Without this oil sealing the eyelid margin, your tears would evaporate almost instantly. Blockages here are the root cause of Evaporative Dry Eye, the most common form of dry eye disease.
Persistent itching at the eyelid margin can sometimes be caused by Demodex, tiny microscopic mites that naturally live on human skin. While usually harmless, an overpopulation of these mites at the eyelash follicles can cause severe inflammation and crusting at the eyelid margin. This condition, known as Demodex blepharitis, often requires specialized eyelid cleansers or tea tree oil treatments to resolve.
Redness and itching are common signs of blepharitis, which is inflammation of the eyelid margin. It can be caused by bacteria or clogged oil glands. Allergies and skin conditions can also be a cause.
Those tiny openings are for your meibomian glands. They are supposed to release a small amount of oil every time you blink. This oil coats the eye's surface and stops your tears from drying out too fast.
Applying eyeliner on the inner rim, or waterline, can block the openings of your meibomian glands. This can lead to irritation, infection, and dry eye symptoms. It is safer to apply makeup only to the outside of your lash line.
You should see an eye doctor if you have symptoms like redness, crusting, swelling, or itching on your eyelid margins that do not go away. Also, make an appointment for any painful bumps or if you have severe dry eye symptoms. A doctor can diagnose the problem and give you the right treatment.
