The patient’s right eye is tearful and swollen, which may be caused by blockage or narrowing of the tear duct, conjunctivitis and impaction. 1. Lacrimal duct obstruction or narrowing: Lacrimal duct obstruction is the main cause of patients’ eye watering. Inflammation, degeneration and other factors may cause narrowing or even blockage of the lacrimal duct, resulting in the inability of tears to flow into the nasolacrimal ducts, which may cause patients to experience tearing, eye swelling and other uncomfortable symptoms. 2. Conjunctivitis: When inflammation occurs in the conjunctiva area of the patient, repeated stimulation of inflammation can cause increased tear secretion, causing tearing, which can also be accompanied by eyelid pain, swelling and other uncomfortable symptoms. 3. Inverted eyelashes: the cornea contains a large number of nerve endings, very sensitive to external stimuli, if the abnormal growth of eyelashes in patients with inverted eyelashes touches the cornea, it can cause the patient to appear irritating tearing, but also eye swelling and other discomforts. It is recommended that patients with tearing and swelling of the eyes should seek prompt medical attention to assess their condition and follow the doctor’s instructions for treatment.
