How to treat miscros meibomian gland dysfunction

Tears nourish the cornea, provide lubrication and act as a refracting surface for light. The tear film lipid layer provides a hydrophobic barrier that stabilises the tear film and retards evaporation of the aqueous layer.1 Insufficient or inferior quality meibum leads to increased tear evaporation rate, the spilling of tears over the lid margin and a poorer refracting surface.2 Other functions of meibum include sealing the lid margins during sleep1 and providing a protective barrier against micro-organisms that may contaminate the eye.3

The meibomian glands are located in the upper and lower tarsal plates of the eyelids. The median number of distinct glands in the upper eyelid is 31, while the number in the lower eyelid was found to be 26.4
