Every day in the clinic, we always encounter children with chalazion, and the most common question from parents is: “Doctor, my child has grown a “pick” and it hasn’t healed for a month, what should I do? In the face of this most common disease in pediatric ophthalmology clinics, let me answer parents’ questions one by one. I. What is chalazion? Chalazion, also known as a chalazion cyst, is a sterile granulomatous inflammation of the lid gland. What is the lid gland? Our upper and lower eyelids (commonly known as the eyelids) have many oil-draining glands that secrete lipids to protect the tears of the eyes from drying out. When the lid glands become inflamed, they prevent oil secretion, resulting in a buildup of lipids and inflammation of adjacent tissues under pressure. The chalazion often has pus, stones or rotten flesh like granulation tissue. Second, why does chalazion occur? Parents in Guangdong often think that their children are “on fire”. In fact, chalazion can occur for a variety of reasons, but ultimately it is a blockage of the lid gland. Common causes include chronic conjunctivitis (chronic allergic conjunctivitis is often combined with chalazion in children), blepharitis, sebaceous glands, or vitamin A deficiency causing glandular epithelial keratinization that blocks the ducts. Therefore, children who love meat, do not love vegetables, picky eaters, children who love sweets more, and children whose diet is too oily have more morbidity. What’s the difference between chalazion and needle picking? This is an acute form of blepharitis, which is characterized by redness, swelling, heat and pain. Chalazion, on the other hand, is usually a chronic inflammation, and unless it is co-infected, it is usually painless and not particularly uncomfortable for the child. How to treat? This is the most important concern for parents. Generally, early detection of hot compresses, anti-inflammatory treatment when combined with inflammation will mostly heal on its own; if it does not heal on its own, or if the cyst breaks into the skin surface affecting the appearance may lead to obvious scarring, or the formation of granulation requires surgery. Parents often hesitate to operate when their child is recommended by the doctor, but in fact it is only necessary when the cyst is too large to be absorbed, so parents should also be reminded to take care of their child to seek medical attention in time to avoid delaying the condition. V. Why does it recur? Some children have surgery and relapse after a while, why? Often children who have surgery have multiple chalazia, and after surgery the lesions are removed there is also scar formation, so the task of the remaining lid glands increases, and if care is not taken to prevent conjunctival inflammation, diet is not changed, and eye health is not attended to inadvertently there may be a recurrence.
