RAI will cause a temporary worsening of thyroid
eye symptoms when you carry the antibodies and usually more so in smokers! Thyroid
eye disease is going to do what it wants to do, to anyone it wants, anytime it wants and as often as it wants, as long as a person has the antibodies and that is, thyroid eye antibodies.
Taking prednisone might help temporarily alleviate the symptoms, but unfortunately does not derail the eye disease.
