The most common types of eyelid bumps are sty, chalazia, papilloma and xanthelasma.
Chalazia (sometimes referred to as Meibomian cyst) is a painless swelling on the eyelid. It is caused by a secretion failure in one of the Meibomian glands that lubricate the eyelid.
Chalazia – Treatment
Small chalazia usually disappear after one to two months. You can accelerate this process by yourself if you massage (gently) eyelids because, by doing so, you will remove the remaining secretion from the gland. Bigger chalazia, which can grow to the size of pea beans, often do not disappear spontaneously, so they should be removed surgically. The eyelid is cut from the inside, and the contents of the chalazia is removed. The surgery is done in a surgical clinic, and only local anesthesia is needed. Chalazia can be infected and, if that happend, the swelling will be bigger, red and painful. In many cases they will disappear by themselved. If it does not retract, incision in the eyelid will be required to allow the discharge of the pus.
Papilla is a non-dangerous growth on the skin, from pink to black color, which can occur anywhere on the eyelid or on the edge of the eyelid. It grows very slowly, ruins the aesthetic appearance of a person and is removed surgically with local anesthesia.
Xantelazma consists of yellow fatty nodules which accumulates underneath the outer part of the eyelid, especially near the nose. This is rarely a feature of some hereditary metabolic disorder, but in most cases the condition is not dangerous. If the nodlues ruin the aesthetic appearance they can be removed, but they may reappear one day.
Other (not so common) nodules that appear on the eyelid include angioma, the type of mole, and the skin tumor called basalioma.
