There are many eye ointments for the treatment of mydriasis. Antibacterial eye ointments are available, such as the most commonly used ointment of chrysin, erythromycin and levofloxacin, which can be used to treat mydriasis. It is a common inflammation caused by bacterial infection of the lid gland, skin, hair follicles, eyelids and other soft tissues, so antibacterial eye ointments and eye drops can be used to treat wheals. The cause of mydriasis is mainly due to a decrease in the local resistance of the eyelid, which leads to the invasion of bacteria and causes inflammation of the eyelid. Usual triggers like unhealthy local eye use, such as prolonged late nights, fatigue, and eye rubbing, can all cause mydriasis to develop.
