Patients with swollen eyes have the following common clinical causes: a. Patients with hemiplegia caused by cerebral infarction may suffer orbital fractures due to inadvertent falls during activities, which may cause localized swelling of the eyes, accompanied by congestion of the eyeballs, at which time the orbital fractures need to be internally fixed and surgically cleared and sutured as soon as possible. Patients with allergies can have allergic allergic reactions after contact with allergens, which can lead to obvious swelling of the eye, and can be treated with oral paracetamol to relieve the symptoms of eye swelling. Third, patients who stay up late for a long time can have short rest time at night, excessive eye fatigue and cause obvious congestion and swelling of the eye tissue, accompanied by the generation of dark circles under the eyes. Patients are advised to regularize their rest time and relax their eyes to avoid repeated swelling of the eyes due to excessive fatigue.
