Chalazion

A chalazion is a small lump or cyst on the eyelid. These cysts are harmless and do not usually cause any significant problems for patients. However, they can lead to an aesthetic concern and in some cases may cause some discomfort. In addition, there is potential for the chalazion to become inflamed or infected, which can lead to other problems with the function of the eye if left untreated.

Chalazions occur due to a blockage in an oil gland within the eyelid. The meibomian glands are located within the eyelid, and open behind the eyelashes. When these are blocked, they cause a backlog of oily fluid within the gland, resulting in a chalazion.

Meibomian glands are more likely to become blocked if you have the predisposing conditions blepharitis (also known as meibomian gland dysfunction) or rosacea.

Chalazion prevention

A chalazion can be prevented. To avoid the development of these cysts, it is important to maintain good eyelid hygiene and ensure the eye area is kept clean to avoid oil and crusts building up causing blockage of meibomian glands.

Chalazion treatment

There are a few different treatments for chalazion. In some cases the chalazion will resolve spontaneously, particularly if you carry out regular hot compresses and massage. However, in some cases, this will fail to get rid of the chalazion, in which case you may benefit from surgery.

Surgery may be necessary or considered due to significant  aesthetic concern or deficient functioning of the eye. During the surgery, a small incision is made inside the eyelid to drain the content of the cyst.
