Hello…it is not uncommon for the eye problems which are associated with being hyperthyroid, for example, blurry, teary, grainly, itchy a little swollen, staring,…to go away with any form of treatment which brings your thyroid levels down. My eyes bother me a bit when my thyroid levels go up or down from normal. They are much better then when I was very hyperthyroid, prior to thyroid bloackade with antithyroid drugs.
This is different from the eye troubles that are a direct result from anti-bodies attack on the eyes..or Graves EYE Disease. That is a much more controversial and difficult subject.
