Meibomian gland disease (MGD) is the leading cause of dry eye disease, affecting millions across the US1,2


Meibomian gland disease occurs when the meibomian glands do not secrete enough high-quality oil to effectively lubricate the surface of the eyes, resulting in dry eye, irritation, and fluctuating vision.1,3

  • Foreign body sensation
  • Burning
  • Eyelid itching
  • Crusting
  • Red eye
  • Light sensitivity
  • Erythema of the eyelids
  • Soreness
  • Excess tearing

Impact of disease

When left untreated, symptoms may worsen and lead to1,5,6:

  • Inflammation
  • Discomfort
  • Blurry vision
  • Alteration of tear film
  • Gland shrinkage and deterioration
  • Permanent and/or progressive gland loss
  • Ocular surface disease

An infestation of Demodex mites may contribute to MGD.7,8

There are currently no FDA-approved pharmacologic treatments for MGD9
