Hyperthyroidism is the abbreviation for hyperthyroidism, and patients with mild infiltrative proptosis of hyperthyroidism are mainly treated by controlling risk factors and topical treatments. Specific treatment measures include wearing tinted glasses to reduce photophobia and shyness, using preservative-free artificial tears during the day and lubricating eye ointment at night, keeping the angle of the atrium moist and covering the cornea, reducing salt intake, and using diuretics to reduce periorbital edema. In patients at high risk for exacerbation of infiltrative proptosis, oral glucocorticoids may be used prophylactically prior to iodine 131 therapy. It is recommended that patients with mild hyperthyroidism with infiltrative synophthalmos seek medical attention in a timely manner and standardize treatment under the guidance of a physician.
