Treatment of chalazion is generally conservative and surgical, depending on the symptoms and stage of development of the disease. Chalazion is a chronic inflammatory granuloma caused by infection of the lid gland, also known as a chalazion cyst, due to retention of lid gland secretions that block the lid ducts and accumulation of secreted lipids that protrude from the lid layer. It occurs mostly in the upper lid and usually has no acute inflammatory manifestations. The chalazion grows slowly, often asymptomatically, and may eventually penetrate the lid conjunctiva to form a polypoid granuloma or may protrude from the lid margin at the opening of the lid gland to form a small, reddish swelling. For smaller chalazia, or for children who cannot easily cooperate with treatment, conservative treatment is now generally used. Larger chalazia rarely disappear spontaneously and in principle require surgery, which should only be performed after the inflammation has subsided if the infection is combined. In clinical practice, about 50% of small chalazia can heal on their own without treatment. In the early stage, in order to accelerate its regression and avoid complications, local cold or hot compresses can be applied at different stages, paying attention to eyelid hygiene, while local antibiotics are applied to the eyes. Corticosteroid injections in the lesion area can also be considered. Tretinoin 0.1-0.2 ml (40 mg/ml) can be injected in the center of the lesion under surface anesthesia, and most of them heal after 1 or 2 injections, which can obtain good results without complications. For larger chalazia or if conservative treatment is not effective, surgical treatment can be chosen. Surgical treatment is mostly performed by performing chalazion incision and drainage + scraping, and postoperative antibiotics are used to spot the eye, and basic recovery can be achieved in about 1 week.
