Needle eye, also called syncope, is scientifically known as mydriasis or blepharitis. In both infants and adults, it is caused by a bacterial infection and is an acute purulent inflammation of the eyelid glands, with typical redness, swelling, heat and pain in the eye. The principles of treatment and disease progression are basically very similar, as follows: 1. Application of antibiotic eye drops: Early antibiotic drops can be applied, infants can be treated with Tobias eye drops, levofloxacin eye drops, fusidic acid eye drops or erythromycin eye ointment, all of which are relatively safe. 2. Local hot compresses: 2-3 times a day, for about 10 minutes each time, can reduce the inflammatory response. 3, Incision and drainage of pus: relatively mild inflammation will basically subside on its own after the above treatment. If the swelling continues to increase after 3-5 days and white spots appear on the skin surface, it is called pus maturation and needs to be incised and drained in the hospital, only after the pus is discharged will the symptoms be significantly relieved, and it will be cured after 3-5 days.
