Treatment: Acutely inflamed cysts may be followed by redness and swelling that spreads throughou the eyelid. In children this must be treated promptly with oral antibiotics, or sometimes admission to hospital and medicine via a 'drip' if it becomes bad enough. Please see your family doctor immediately.
Most inflamed cysts settle within 1-2 weeks. Using a warm cloth for 5 minutes 2-3 times per day on the lid may help, but eyedrops are seldom useful. Persistent or large cysts may require a short surgical procedure (small cut through inside of eyelid, opening the cyst, so that the inflammatory material can be removed), which in children less than 14 will always require general anaesthesia.
Some children with recurrent or stubborn cysts may benefit from treatment with a 3-week course of an antibiotic, Erythromycin. This is to improve the function of the eyelid glands, hence preventing the formation of cysts.
