Meibomian Gland Dysfunction (MGD)
Meibomian Gland Dysfunction (MGD) is a chronic, diffuse abnormality of the meibomian glands, commonly characterized by terminal duct obstruction and/or qualitative/quantitative changes in the glandular secretion. It may result in alteration of the tear film, symptoms of eye irritation, clinically apparent inflammation, and ocular surface disease.
Patients often present with signs and symptoms of dry eye caused by MGD such as:
- Burning and redness
- Ocular fatigue
- Foreign body sensation
- Sensitivity to light
- Excessive tearing
- Symptoms worsen later in the day
- Transient blurring
- Contact lens intolerance
