These findings, combined with the clinical conditions-an ophthalmologic evaluation (that showed the presence of exophthalmos without lagophthalmos and visual acuity deficiency), thyroid ultrasound, and TSH receptor antibody positivity-led to a diagnosis of Graves' disease.
Thyroid hormone levels and thyroid-stimulating hormone receptor antibody (TRAb) levels were measured, and the degree of exophthalmos was measured in all patients.
The therapeutic outcomes defined as: i) reduction of the clinical activity score (CAS) ≥2 points or ii) reduction of proptosis ≥2 mm or iii) improvement of diplopia according to the Gorman score were also studied in relation to treatment schedule, age, gender, duration of thyroid or GO, smoking habits, and serum TSH-receptor autoantibodies levels.
