Hello and welcome! This is a nice article from the University of Michigan Kellogg Eye Center that talks about the cause and course of TED, as well as treatment options. Every patient is different, so it’s hard to predict exactly what the course of the disease will be for you.

The good news is that once TED burns itself out, the vast majority of patients will NOT see a recurrence, although it is certainly challenging to deal with the active phase — and any subsequent surgeries that may be required.
Take care!
