Meibomian glands are small, modified sebaceous glands located in the eyelids. They produce a lipid-rich substance called meibum, which is essential for maintaining the health and function of the tear film. The meibomian glands are connected to the eyelid margin via small ducts, which can become blocked or inflamed, leading to meibomian gland dysfunction (MGD).

MGD is a common condition characterized by the obstruction of the meibomian gland ducts, resulting in impaired meibum secretion. This can lead to symptoms such as dryness, irritation, redness, and a sensation of a foreign body in the eye. MGD can be caused by various factors, including aging, hormonal changes, and certain medications.

The diagnosis of MGD typically involves a comprehensive eye examination, including a slit-lamp examination to assess the eyelid margin and meibomian glands. Treatment options for MGD may include warm compresses, eyelid massage, topical medications, or, in severe cases, surgical intervention to clear the blocked ducts.

Prevention of MGD involves maintaining overall eye health, avoiding smoking, and using artificial tears as needed. Regular eye examinations can help detect MGD early and manage symptoms effectively.
