The condition of mydriasis, if a localized abscess forms and breaks down, will result in localized pus or bleeding. Once this situation occurs, it is recommended to first keep the eye locally clean, clean the local blood or purulent secretions with saline or sterile cotton swabs in a timely manner, and to continue to use antibiotic drugs to control the inflammation. If the pus is completely drained from the pus cavity after the breakdown, the disease will soon return to normal and the broken skin will soon crust over. If the pus cavity is not completely drained after the ulceration, but part of it remains, even after the wound is healed, the local hard nodes can still be felt, and it is difficult to be cured by conservative methods, so it is recommended to go to the hospital as soon as possible for surgical treatment to incise and drain the pus.
