Chalazion

A small tumor of the eyelid.

Non-malignant small swelling on the eyelid that often requires surgical removal; also called meibomian cyst.

A small, firm, painless lump near the edge of the eyelid, sometimes related to blockage of a meibomian gland.

An inflamed, tender lump on the eyelid caused by the blockage of a small gland that produces the oil layer of tears. A chalazion appears some distance from the edge of the eyelid, unlike a stye, which occurs close to the eyelashes. A chalazion may cause discomfort in the eye, sensitivity to light, and increased tearing. Over time a chalazion forms a cystlike swelling, which may put pressure on the eyeball and distort vision (astigmatism) or become infected. In many cases, chalazions resolve on their own within a few months. Applying warm compresses (a clean cloth soaked in hot water and wrung out) for lo minutes four times a day may speed healing. If swelling continues, a chalazion can be drained surgically under local anesthesia in the doctor’s office.

A swollen sebaceous gland in the eyelid, caused by chronic inflammation following blockage of the gland’s duct. The gland becomes converted into a jellylike mass, producing disfigurement of the lid. It may become secondarily infected, when it will be painful and may discharge. Treatment is by application of antibiotic ointments or surgical removal of the gland.

A benign, granulomatous lesion analogous to a sebaceous cyst developing on the eyelids, formed by distention of a meibomian gland with secretion.

A chalazion refers to a painless, round swelling that develops in either the upper or lower eyelid. It occurs due to the blockage of one of the meibomian glands responsible for lubricating the eyelid edges. Chalazions are sometimes referred to as meibomian cysts. They can manifest at any age and may be more prevalent in individuals with skin conditions like acne, rosacea, or seborrheic dermatitis.

When a chalazion becomes infected, the associated symptoms may include increased swelling, redness, and pain in the eyelid. In cases where a large swelling exerts pressure on the front of the eye’s cornea, it can lead to blurred vision. Approximately one-third of chalazions resolve without treatment; however, surgical removal may be necessary for larger cysts.
