Chronic Eyelid Disease

Eyes are one of the most important connections we have to the rest of the world. However, when practicing good hygiene many people forget about their eyes. Similar to the way we brush our teeth daily and visit the dentist, we should clean our eye lids and lashes daily and visit our eye doctors on a regular basis.

The Role Of Lid Hygiene In Ocular Surface Disease prevention is an important part of any preventative eye care.The key function of the eyelid is to regularly spread the tears and other secretions of the eye surface to keep the cornea moist and protect the eye from dirt and debris. The blink reflex protects the eye from foreign bodies while spreading the tear film evenly across the cornea.  Eyelids also keep the eyes from drying out when asleep. There are many chronic eyelid conditions caused by meibomian glands dysfunction or MGD.

The meibomian glands (or tarsal glands) are a special kind of sebaceous gland at the rim of the eyelids inside the tarsal plate, responsible for the supply of meibum, an oily substance that prevents evaporation of the eye’s tear film.

Meibum prevents tear spillage onto the cheek, trapping tears between the oiled edge and the eyeball, and makes the closed lids airtight. There are approximately 50 glands on the upper eyelids and 25 glands on the lower eyelids.

Dysfunctional meibomian glands often cause dry eye, one of the more common eye conditions. They may also contribute to blepharitis.
