Meibomian glands (English: Meibomian glands) are located in the upper and lower eyelids. The glands produce oil and fat (lipids) that together with the tear fluid (from the tear fluid) prevent the eyes from getting dry.
Dry, irritated eyes and blurred vision (blepharitis) may be caused by reduced function (dysfunction) in Meibomian glands or in too little tear production (other causes must also be ruled out).
- By Sjögren's disease there is reduced tear production, but at the same time reduced function in Meibomian glands is also possible.
Most people with symptoms are over the age of 40. The condition is more common among Asians than ethnic Norwegian. Sjögren's syndrome is thought to be a risk factor. Makeup can also cause obstruction of the channels in the Meibomian glands and thus symptoms
Heat and light pressure against the eyelids can relieve by increasing the excretion of the glands. Eyelid can prescribe special eye drops, for example Ikervis containing ciclosporin.
