Exacerbation of Thyroid Eye Disease and Dysthyroid Optic Neuropathy During Pregnancy: A Case Report.

ABSTRACT

A 37-year-old, never-smoker, pregnant woman diagnosed with Graves' disease who had stable thyroid eye disease (TED) before pregnancy presented with aggravated proptosis and eyelid swelling at 13 weeks of pregnancy. Despite the administration of local triamcinolone and 3 cycles of corticosteroid pulse therapy from 25 to 28 weeks, the patient's visual acuity decline necessitated postpartum orbital decompression surgery. Although TSH receptor antibody (TRAb) levels decreased during the mid- to late term of pregnancy, the TED worsened. This finding suggests that factors other than anti-TSH receptor antibodies may have a significant effect on disease severity.
