If a patient with hyperthyroidism has eye pain, it is important to go to a proper hospital to confirm that the patient has thyroid-related eye disease. If the patient is diagnosed with thyroid-related eye disease, medication or radiation or surgery should be given. Thyroid-associated ophthalmopathy is characterized by blepharoconstriction, late fall of the upper eyelid, diplopia, eye movement disorders, conjunctival edema, congestion, corneal ulcers, dry eyes, photophobia, etc. The treatment used after the diagnosis is confirmed is medication, radiation or surgery. The treatment used after diagnosis is also based on the patient’s condition. Pharmacological treatments include glucocorticoids, immunosuppressants, and so on.
