I believe the statistic is less than 50% of those who have Graves
develop any symptoms of Graves
. Each is caused by different sets of antibodies. Some people get eye disease with
out ever having thyroid problems. And, of those with
Graves/thyroid who do develop eye disease, only about 5% of those ever develop serious enough eye problems (bulging
, eyelid retraction, double vision, optic nerve issues) to warrant surgery.
