  • GO=Graves’ ophthalmopathy; GTD=Graves’ thyroid disease.

  • TES=total eye score is calculated by multiplying each class of the NO SPECS system (except class 5) with its grade of severity (0=0; a=1; b=2; c=3 points), yielding a maximum total score of 45 points14 (Since all patients had symptoms, class 1 is not taken into account).

  • CAS=clinical activity score is based on signs of pain, redness, swelling, and impaired function (range 0-7).
