I forgot to post the site for the Mayo Clinic ophthamology site. Sorry.
http://www.mayo.edu/Mayo_Ophtho/Graves_info.html
This site has information more specific to Graves Eye Disease.
Occasionally, between the time the site address is posted, and the time I try to access it, I have found that the address has changed. This is particularly true of long addresses, like the Mayo one, where you are going directly to some other location within the primary site. If you encounter this problem, try accessing only the primary site and working your way from there, i.e. http://www.mayo.edu/
Hope these help.
