Eyelid cysts are usually chalazia, and whether they will disappear on their own is determined by the size of the chalazia and cannot be generalized. Chalazion is a chronic inflammatory granuloma of the lid gland based on obstruction of the lid drainage ducts and retention of secretions, also known as a chalazion cyst, and is a common condition that can affect both children and adults. Smaller chalazia may disappear on their own or be treated with heat or physical therapy to promote dissipation and absorption; larger chalazia may not disappear on their own and patients need to be treated with surgical removal, which must remove the wall of the chalazion to prevent recurrence. In addition, patients should pay attention to the cleanliness and hygiene of the eyes in daily life, do not rub the eyes with dirty hands or overuse the eyes, try to eat a light diet, avoid eating greasy, spicy and stimulating food.
