We assess the number of functional oil glands (meibomian glands) on your lower eyelid by gently pressing against the lower lid margin. The Lipiscan imaging device is used to take dynamic high-definition images of the meibomian glands in the lower and upper eyelid. It allows our doctors to quickly identify meibomian gland dysfunction (MGD) and gland dropout, which is the leading cause of dry eye symptoms. Early detection of MGD is essential as dry eye symptoms can get worse and if left untreated may lead to permanent damage.
The tear film consists of three layers - a mucus layer, aqueous layer and lipid layer. A healthy tear film is largely responsible for everyday visual comfort. The outermost oily layer of the tear film, which is secreted by the meibomian glands is the protective coating on the ocular surface that acts as a barrier to evaporation keeping the middle watery layer intact. In meibomian gland dysfunction the oil production from these glands is inhibited causing the watery layer of the tear film to evaporate faster, leaving the eye surface exposed.
When the tear film is destabilized or compromised, the ocular surface becomes easily irritated and may become red, scratchy and uncomfortable. You can experience eye fatigue, difficulty with contact lens wear and recurrent styes.
