What is a chalazion? Chalazion, also known as a chalazion cyst, is a chronic inflammation of the chalazion gland. What are the signs of a chalazion? Appearance: Nearly round, hard, well-defined, immovable bumps (“bumps on the eyelid”) that are visible on the skin surface, with no adhesions to the skin and no redness or swelling on the skin surface at the site of the bumps; they are not painful to touch; they are visible when the eyes are closed but look smaller or even invisible when the eyes are open. Size: can be large or small, small to the size of a grain of rice (can only be found by careful touch); large can grow to the size of a small flower of rice. Location: Chalazia can occur in the upper or lower eyelids. Number: It can occur singly or in multiple cases. Some patients have multiple chalazia in the upper and lower eyelids, or even in the left and right eyes at the same time. What should I do if I have a chalazion? Small chalazia can absorb on its own, so no treatment is needed; if the chalazia grows gradually, it can break down and form granuloma on its own, or grow to a certain extent and cause discomfort in the eye, it can be removed surgically. Chalazion may also be secondary to infection. If secondary infection occurs, redness, swelling, and pain may occur (clinical manifestations are similar to those of internal wheals), and anti-inflammatory treatment (e.g., topical eye drops such as tobramycin and ofloxacin; eye ointments such as erythromycin eye ointment and gentamycin eye ointment; oral or systemic antibiotics) and local hot compresses are required. If an abscess forms, surgery is required; if the inflammation subsides and the bumps are still present, surgery is also required. Surgery for chalazion is simple and is a minor procedure that can be done in a few minutes and does not require hospitalization.
