The treatment of mydriasis depends on the degree of mydriasis: 1. In the early stage, when the symptoms are mild and the local inflammation is not obvious, you can apply local heat compresses (10-15 min each time, 3-4 times a day) in order to promote blood circulation in the eyelids, relieve the symptoms and promote inflammation, and use local antibiotic eye drops or ointment (such as tobramycin eye drops 4-6 times a day, one drop each time; erythromycin eye ointment, 1 time before bedtime, squeeze 3-4 mm long each time). Each time squeeze 3-4mm long); 2. Those with obvious local inflammation, recurrent episodes or heavy conditions with systemic reactions, especially the elderly, children and some patients with poor body resistance, will need oral or intravenous antibiotics; 3. If an abscess is formed, it is necessary to go to the hospital to incise and drain the pus. Note: wash your hands before and after ordering eye medication, do not touch your eyes when ordering eye medication, try to drop eye medication into the space between the lower eyelid and the eye, do not drop onto the cornea; pay attention to your diet during treatment, drink less alcohol and eat less spicy food; pay attention to rest and stay up less late; do not squeeze!
