Macroglossia is not contagious. Macroglossia is an acute purulent inflammation of the eyelid glands, including inflammation of the lid glands, eyelash follicles, or accessory glands. Most are caused by staphylococcal infections, particularly Staphylococcus aureus. Internal mydriasis inflammation is confined to the lid gland and manifests as congestion, swelling, and pain in the eyelid and limited congestion and edema on the conjunctival surface of the lid, with yellow pus spots forming 2-3 days later. In external mydriasis inflammation at the lid margin at the root of the eyelashes, the eyelid is locally congested, swollen, and painful, and hard nodules can be palpated. When the lesion is located in the external canthus, edema of the bulbar conjunctiva may occur, and after 2-3 days a pus point forms at the root of the eyelash, which may break down and drain on its own. In severe cases, redness and swelling of the ipsilateral side, enlarged lymph nodes in front of the ear or under the jaw, and even systemic toxic symptoms such as fever, headache, nausea and vomiting may occur.
