In the early stage of treatment of mydriasis, hot compresses can be applied to promote softening and absorption if it is hard, and cold compresses can be applied to reduce swelling and relieve pain if there is a fluctuating feeling or the appearance of pus head in the later stage. At the same time, local antibiotics can be applied to the eyes, and oral or systemic antibiotics can be used for more severe symptoms. Surgical excision and drainage of the abscess may be considered. Blepharitis is an acute, painful, purulent, nodular inflammatory lesion of the eyelid glands. In the early stages of treatment, if the nodule is small, hot compresses can be applied to promote the softening and absorption of the nodule, but if there are fluctuations or small pus heads in the later stages, the hot compresses should be stopped. 3-4 times a day for 15 minutes each time. Topical antibiotic eye drops help control the infection, such as levofloxacin, tobramycin, chloramphenicol, and rifampin eye drops. More severe symptoms or the development of eyelid cellulitis require oral or intravenous antibiotics. If the swelling matures into an abscess, a myringotomy is also possible. The incision for external blepharitis is made on the skin surface parallel to the lid margin to reduce scar formation; the incision for internal blepharitis is made on the conjunctival surface, perpendicular to the lid margin, to avoid damaging too many glands. This can lead to cavernous sinus thrombosis or sepsis, which can be life-threatening and require systemic administration of sensitive antibiotics in adequate amounts and treatment according to the principles of sepsis. In summary, the treatment of wheals can be local cold or hot and wet compresses and local antibiotics in mild cases, and systemic antibiotics and surgical incision to drain the pus in severe cases. Do not squeeze the wheals by hand without permission.
