Temporal relationship between onset of Graves' ophthalmopathy and onset of thyroidal Graves' disease.
The temporal relationship between the onset of Graves' ophthalmopathy and the onset of thyroidal Graves' disease was evaluated in 125 consecutive patients with Graves' ophthalmopathy. Thyroidal Graves' disease--past or present--was clinically evident in 99 patients (79%): hyperthyroidism in 3 cases. Thyroid disease preceded the eye disease in 37 patients, it occurred simultaneously with the eye disease in 39 patients, and it developed after the eye disease in 23 patients (in 16 cases within one yr after the onset of eye disease). The age at the onset of thyroid disease (38.7 +/- 12.9 yr) was lower than the age at the onset of ophthalmopathy (41.8 +/- 12.5 yr; p less than 0.001). Among the 26 clinically euthyroid patients (21%) laboratory evidence of thyroidal Graves' disease was found in 14 cases (11%): abnormal TRH test, n = 9; normal TRH test but abnormal T3-suppression test, n = 4; normal TRH and T3-suppression tests but positive thyroid stimulating antibodies, n = 1). We conclude that Graves' ophthalmopathy as a rule develops at a time when thyroid autoimmunity also exists. This strongly suggests a common factor in the pathogenesis of thyroidal and ocular expressions of Graves' disease.
