A chalazion, also called a chalazion cyst, is an obstruction of the opening of the chalazion gland and is not painful, while a chalazion (also called a pinhole) is a bacterial infection of the chalazion gland with significant redness, swelling and heat. Many people, especially children, are prone to growing chalazia and may have multiple episodes. If there are no signs of infection and inflammation (redness, swelling, pain), you can apply heat without antibiotics and it will mostly absorb itself after a few weeks, but if it does not decrease but increases in size in a month, you should see an ophthalmologist. Hot compresses (four times a day for 15 minutes each time) and lid gland massage will speed up the discharge of oil. In the case of mydriasis (red, painful nodules on the eyelid skin), conservative treatment should be used first (for both men and women): hot compresses (to speed up blood circulation and bring in more of your own white blood cells), antibiotic eye drops, and antibiotic eye ointment. Topical eye medication is rarely absorbed systemically, so there is no need to worry about side effects. Oral antibiotics can also help reduce inflammation when mydriasis is severe, but use with caution during pregnancy and lactation! Surgery is considered only when conservative therapy does not work. Recurrence of wheals and chalazion is not uncommon and is related to air pollution, decreased resistance (e.g., in children), skin characteristics (e.g., acne, oily skin), blepharitis, poor local hygiene, and systemic conditions (e.g., diabetes). Some recurrences and reinfections can reappear immediately after the wound is closed for several days. Recurrent episodes in the same area in the elderly should be considered as a possible tumor and aggressive medical attention should be sought.
