The common name for mydriasis, also known as needle’s eye or syncope, is called blepharitis, which is an acute purulent inflammation of the eyelid glands caused by a bacterial infection, and is considered by Chinese medicine to be caused by fire. Localized inflammation of the eye can be characterized by typical redness, swelling, heat and pain, for example, if the child has recently stayed up late and not rested well, or if the diet is spicy or stimulating, or if the child may be wearing more clothes and the temperature is higher. If the inflammation is mild, antibiotic eye drops or local hot compresses, it will subside on its own. If the inflammation is heavy, the local area will mature and form a pus point, then you have to go to the hospital to cut open and drain the pus, after the pus is discharged, the local inflammatory symptoms will soon be relieved, and the inflammation will basically heal in 3-5 days after the incision.
