'''Meibomian Gland Dysfunction''' (MGD) is a common eye condition affecting the [[Meibomian glands]] located in the eyelids. These glands produce the oil layer of the eye's tear film, which is crucial for preventing the evaporation of the eye's tear layer. MGD occurs when the Meibomian glands do not secrete enough oil or if the oil they produce is of poor quality. This can lead to dry eye symptoms, as the tear film evaporates more quickly than normal. MGD is a leading cause of [[Dry Eye Syndrome]]. | '''Meibomian Gland Dysfunction''' (MGD) is a common eye condition affecting the [[Meibomian glands]] located in the eyelids.

Meibomian Gland Dysfunction (MGD) is a common eye condition affecting the Meibomian glands located in the eyelids. These glands produce the oil layer of the eye's tear film, which is crucial for preventing the evaporation of the eye's tear layer. MGD occurs when the Meibomian glands do not secrete enough oil or if the oil they produce is of poor quality. This can lead to dry eye symptoms, as the tear film evaporates more quickly than normal. MGD is a leading cause of Dry Eye Syndrome.
Causes and Risk Factors[edit]
The exact cause of MGD is not fully understood, but several factors are known to contribute to its development. These include:
- Ageing: The function of Meibomian glands tends to decrease with age.
- Hormonal changes: Particularly those associated with menopause.
- Eyelid hygiene: Poor eyelid hygiene can lead to blockages of the Meibomian glands.
- Contact lens wear: Long-term use of contact lenses can increase the risk of MGD.
- Environmental factors: Exposure to dry, windy, or smoky environments can exacerbate symptoms.
- Other health conditions: Such as Rosacea, Seborrheic dermatitis, and allergies.
Symptoms[edit]
Common symptoms of MGD include:
- Dryness
- Irritation
- Burning sensation
- Redness
- Blurred vision
- Eyelid crusting
Diagnosis[edit]
Diagnosis of MGD involves a comprehensive eye examination. An eye care professional may use various tests to assess the quality and quantity of the oil produced by the Meibomian glands, the stability of the tear film, and the overall health of the eyelids.
Treatment[edit]
Treatment for MGD aims to improve the function of the Meibomian glands and the quality of the tear film. Approaches include:
- Warm compresses: Applying warm compresses to the eyelids can help liquefy the oil in the Meibomian glands, facilitating its flow.
- Eyelid hygiene: Regular cleaning of the eyelids can remove any debris that may block the Meibomian glands.
- Artificial tears: Over-the-counter lubricating eye drops can provide temporary relief from dry eye symptoms.
- Prescription medications: In some cases, antibiotics or anti-inflammatory medications may be prescribed to reduce eyelid inflammation.
- In-office procedures: Techniques such as LipiFlow thermal pulsation therapy can help clear blockages in the Meibomian glands.
Prevention[edit]
Preventive measures for MGD include maintaining good eyelid hygiene, using a humidifier in dry environments, taking breaks during long periods of screen use to reduce eye strain, and wearing sunglasses outdoors to protect the eyes from wind and UV exposure.
