PURPOSE: To propose criteria for the diagnosis of Graves' ophthalmopat
hy. METHODS: We reviewed the evolution of nomenclature describing Grav
es' ophthalmopathy and the diagnostic schema used in key published rep
orts. RESULTS: A laboratory test or clinical finding pathognomonic for
Graves' ophthalmopathy currently is not available or recognized. Exta
nt diagnostic criteria may exclude appropriate cases. CONCLUSIONS: Gra
ves' ophthalmopathy is considered to be present if eyelid retraction o
ccurs in association with objective evidence of thyroid dysfunction or
abnormal regulation, exophthalmos, optic nerve dysfunction, or extrao
cular muscle involvement, The ophthalmic signs may be unilateral or bi
lateral, and confounding causes must be excluded. If eyelid retraction
is absent, then Graves' ophthalmopathy may be diagnosed only if exoph
thalmos, optic nerve involvement, or restrictive extraocular myopathy
is associated with thyroid dysfunction or abnormal regulation and if n
o other cause for the ophthalmic feature is apparent.
