Meibomian Gland Dysfunction

Meibomian Gland Dysfunction (MGD)

Meibomian Gland Dysfunction is a leading cause of evaporative dry eye. As such many people these days are told that they have MGD, and specific treatments have been devised to treat the condition and thereby improve Dry Eye Syndrome.


The Meibomian Glands are oil producing glands sited within the top and bottom eyelids. Healthy glands produce a clear thin oil that is secreted out through small pores in the eyelid margins. The oil seeps into the tears and under normal conditions is blended in to the tear film thoroughly. Its function is to prevent the tears from evaporating away so quickly.  

In some individuals, the glands become dysfunctional. A number of things can happen such as blockages within the glands, inflammation, gland die off and plugging of the openings. Gland dysfunction results in changes to the amount and quality of the oily secretion and hence leads to Dry Eye.


Treatment of Meibomian Gland Dysfunction 

Correct treatment of this condition, lies with analysis  of each  persons glands to determine the specific cause of the dysfunction.  Treatment is aimed at restoring correct functioning of the glands although in severe cases full resolution may not be possible.  

Treatment options include antibiotic tablets, heat therapy, anti-inflammatories and lid margin exfoliation.  Supportive therapy, by way of new drop formulations specifically targeted for Evaporative Dry Eye may be needed to boost the tear film while the glands improve.
