    PURPOSE: The aim of this study is to evaluate the response of Graves’ orbitopathy to
    irradiation, and to specify the prognostic factors allowing one to better define the indications of
    orbital radiotherapy. METHODS AND MATERIALS: From 1977 to 1996, 199 patients
    received bilateral orbital irradiation delivering 20 Gy in 10 fractions and 2 weeks for a
    progressive Graves’ orbitopathy. 195 patients were seen between 1 and 6 months after
    radiotherapy. The different symptoms were studied and their response to radiation was
    analyzed. Factors such as age, sex, evolution of thyroid disease, history of symptoms, and
    previous or combined treatments were analyzed. RESULTS: The results revealed that 50
    patients (26%) had a good or excellent response, 98 (50%) had a partial response, 37 (19%)
    were stable, 10 (5%) had a progression of disease. The signs that best responded to
    radiotherapy were the infiltration of soft tissues and the corneal involvement. Responses of
    proptosis or oculomotor disorders were more complete when these signs were not advanced at
    the time of treatment. Irradiation seemed to have the same efficacy when applied as first-line
    treatment or after failure of corticosteroids. Neither modality of treatment of hyperthyroidism
    nor thyroid status at the time of orbital irradiation modified the results. The best results were
    recorded for early or moderately advanced presentation (p = 0.05). Patients treated within a
    delay of 7 months after the beginning of the ophthalmopathy had better responses than patients
    treated later (p = 0.10). CONCLUSION: Radiation therapy was successful in Graves’
    orbitopathy by stopping the progression of disease in almost all cases, by improving the comfort
    of patients, by obtaining objective responses, and by avoiding surgical treatments particularly
    when signs were moderate.
