MGD/Dry Eye Syndrome

Meibomian Gland Dysfunction (MGD)

MGD is a chronic and progressive condition

What is Dry eye?

Dry eye is a medical condition with health and lifestyle consequences if left untreated. There are two primary forms of Dry Eye – Evaporative (which is associated with deficiency in the oily layer of your tears) and Aqueous Deficient (which is associated with deficiency in the watery layer of tears). LipiFlow® addresses Evaporative Dry Eye, which is the most common cause of dry eye symptoms. As part of our Dry Eye Evaluation, the doctor will use several tests to assess and identify the root cause of your Dry Eye symptoms and recommend the best treatment for you.

What are meibomian glands?

Meibomian glands are the oil producing glands of your eye lids. If these glands do not produce enough oil or become blocked, it may contribute to your symptoms of dry eye.

The outermost layer of the tear film, the lipid layer, is composed of oils from meibomian gland secretions that lubricate, prevent evaporation, and perform barrier functions. If these glands become obstructed, qualitative and quantitative changes in glandular secretion may lead to symptoms of eye irritation, clinically apparent inflammation, and ocular surface disease.

Eighty-six percent of patients diagnosed with dry eye have symptoms associated with an unstable tear film due to compromised meibomian gland function.

Using a tool called LipiScan™, we are able to take a picture of your meibomian glands (known as “high-definition meibography”) in order to assess their condition and determine the best course of treatment to optimize the health of your eyes and eyelids. This scan is an integral component in determining the cause of your dry eye symptoms. 

Below you will find examples of the images the LipiScan™ tool produces to visualize your meibomian glands. Dynamic IlluminationIn each of these photos, you can see healthy meibomian glands as the complete columns of “bubbles” in the eyelids to the left and right of center.
