There is no treatment for antibodies. The only thing that can be done, is to get rid of the thyroid so antibodies can't attack it. Even the smallest amount of thyroid left the antibodies can attack, but perhaps not as severe or destructive as in a total thyroid.
The laryngeal nerves and parathyroid glands are located very close to the thyroid, so as not to damage these during surgery a small portion of the thyroid is left . Then RAI is done to disable the remaining thyroid that is left.
TED is an autoimmune disorder which has its own antibodies closely related to thyroid antibodies. Thyroid antibodies can aggravate TED (among other things such as smoking, etc.) therefore by getting rid of the thyroid through surgery and then disabling the remaining with RAI, antibodies cannot attack the thyroid (a thyroid thats not there) therefore worsening the condition of TED. However in some cases the condition progresses regardless of what is done to the thyroid gland (because TED has its own antibodies), therefore there is no satisfactory treatment. Options other than getting hyper/hyper under control which helps some, are strong drugs such as steroids or immunosuppressive drugs to prevent the unlikely occurrence of optic nerve swelling and blindness, and orbital decompression or radiotherapy.
In other words, TED has its own antibodies that directly attack the eyes and its going to do what its going to do, wherever it wants to do it, and, as many times as it wants to do it. Each attack is dealt with and treated as it comes. Its just a matter of luck.
Good Luck.
You do not need another RAI (I-131 treatment). If I read your post correctly, you said that your taking a thyroid supplement & your thyroid lab is normal & that only your TSI is elevated. The TSI is the graves antibody produced by the immune system which attacks the thyroid making it over produce thyroid hormones, therefore making you hyper.. They destroyed most oif not all of your thyroid with the RAI treatment so that it will not react to the TSI antibody. TED can be made worse by RAI or it may occur after RAI esp. if you were not brought to a normal thyroid lab state before you were given RAI or if you were not treated with Prednisone ( a steroid which supresses your immune system ) after you had your RAI treatment. You also should not be allowed to go into a hypo state after RAI, this will also induce TED.
MY thyroid lab is also normal & my TSI is still elevated at 195 with normal being <25. I had RAI 15 months ago & within 3 months my TSH was 89 & I developed a full blown case of TED. I just had orbital decompression surgery on March 21. I also had to travel 4 hours as ocular plastic surgerons experienced with thyroid eye
