 Along the edge of the eyelids, there are glands meibomian glands that produce and deliver oils meibum onto the tear film. These oils serve to slow down the evaporation of tears. The meibomian glands may become obstructed due to change in meibum quality. When meibum thickens and solidifies, it plugs the gland openings and oils can no longer reach the tear film. The blockage of the glands is the primary cause of meibomian gland dysfunction MGD, and may result in symptoms of dry eye burning, stinging, grittiness, etc.. The typical treatment for MGD is a procedure called warm compresses. It is a combination of applying heat and pressure to the eyelids for approximately 10 minutes to melt the meibum, unplug the gland openings, and allow oils to flow normally onto the tear film once again. One way to apply heat to the eyelids is by using the MGDRx EyeBag. The EyeBag is microwaved for 30-40 seconds under full power, and is placed over the closed eyes for approximately 10 minutes. The eyes are gently massaged afterwards.
