Treatment of hyperthyroidism does not treat
Graves Eye
Disease. The symptoms of GED are frequent tearing (I developed eye
problems months before I developed thyroid problems, I thought it was allergies), gritty feeling in the eyes. As the eye disease progresses, the eyes can bulge out of the sockets, lid lag and retraction can develop and double vision can develop.
As far as anit-thyroid meds go, most docs will treat with them for 12-18 months before recommending RAI or surgery.
