![]() Without any abnormality, this oily liquid is easily secreted from the meibomian glands. The meibomian glands normally secrete a lipid secretion, known as meibum which is a clear or pale yellow oily liquid. Particularly, the lipid layer is an essential component of the tear film, providing a smooth optical surface and retarding evaporation from the eye. These three layers work collaboratively to help maintain the health of the eyes and prevent eye infection. Tear film is made up of three intertwined layers – a lipid layer, an aqueous layer and a mucous layer. ![]() These glands secrete oil which coats the surface of the eyes and keeps the water component of tears from evaporating. There are approximately 30 to 40 meibomian glands in the upper eyelid and 20 to 30 glands in the lower eyelid. Meibomian glands are the tiny oil glands which line the margin of the eyelids. Knowing warning signs of meibomian gland dysfunction allows for early diagnosis and appropriate treatments before dry eye syndrome develops. If the oil gland openings get plugged up or obstructed, meibomian glands do not secrete sufficient oil into the tears, leading to evaporative dry eye that often causes eye irritation and eye lid infections. The normal tears are made up of three layers – a lipid layer, a watery or aqueous layer and a mucous layer. One of contributing factors to dry eye syndrome is meibomian gland dysfunction (MGD) defined as blockage or other abnormality of the meibomian glands, tiny oil glands which line the margin of the eyelids. ![]() eye irritation, redness, discharge, easily fatigued eyes and blurred vision might be potentially associated with dry eye syndrome.
