Meibomian gland dysfunction

The oil glands behind a stable tear film

Meibomian glands inside the eyelids supply oil to the tear film. This oil helps slow evaporation. With meibomian gland dysfunction, or MGD, the amount or quality of the oil changes, often with blocked gland openings and eyelid inflammation. The tear film can become less stable even when the eyes still make watery tears. ¹; ²

What you might notice

MGD may contribute to burning, grittiness, watering, redness or vision that becomes less clear between blinks. Eyelid irritation can overlap with blepharitis and other forms of dry eye. Aging, skin conditions such as rosacea and changes in blinking can contribute. An examination helps identify which factors are present. ²; ³

What the clinician checks

The evaluation can include the lid margins, gland openings, oil quality and how readily oil is released. Tear-film testing and, when useful and available, gland imaging add context. The findings guide treatment; one symptom or test does not describe the whole problem. ⁴

Treatment focuses on gland function and inflammation

Common options include lubricating drops, gentle lid hygiene and clinician-directed warming of the eyelids. Depending on the examination, prescription treatment or in-office gland-focused care may be considered. IPL is another option for selected patients with MGD-associated dry eye. ²

Beatific Vision tailors meibomian-gland-specific care after evaluation. Ask which treatments fit your findings and what each is intended to improve. If home warming is recommended, ask for clear instructions on temperature and timing. Avoid forcefully squeezing the eyelids or attempting gland expression with tools at home.

What to expect

Treatment may improve comfort and tear-film stability, but ongoing care is often needed. A plan should include a review point, a way to judge improvement and a next step if symptoms persist. Your clinician will explain what treatment can realistically change and how to maintain any improvement. ⁵

When to seek urgent care

Arrange an eye examination for persistent or worsening symptoms. Sudden loss of vision, severe eye pain, marked light sensitivity or an eye injury needs urgent assessment. A painful red eye in a contact-lens wearer also needs prompt care; remove the lenses and seek advice rather than assuming it is dry eye. ⁶; ⁷; ⁸
