The self-healing process of mydriasis is generally like this: first, in the early stages of the disease when bacteria have just invaded, it usually shows typical inflammatory manifestations, localized redness, swelling, heat, and pain in the eyelid, eyelid edema, conjunctival edema, and local pain will be more pronounced, and as the disease progresses, the local inflammation is gradually limited in extent, and most patients are likely to become smaller and smaller until it is completely absorbed, which belongs to This is a form of self-healing. The second type refers to the formation of a local abscess, but the scope of the abscess is not very large, and the pus in the abscess will be gradually discharged to the conjunctival surface or the skin surface, and after the formation of a local pus spot, it may break down and the pus in it will be discharged, and this process belongs to another self-healing process. In the third case, a localized abscess is formed, but it does not break down, but remains in the eyelid for a long time, in which case it needs to be restored to normal by means of surgery.
