title: [Dysthyroid optic neuropathy in pregnancy].
abstract: BACKGROUND
  While development of thyroid eye disease is rarely observed in pregnant women, here we report three cases of pregnant patients with severe dysthyroid optic neuropathy (DON).
  
  
  METHODS
  Case 1, a 30 year-old woman with thyroid eye disease diagnosed during pregnancy and DON occurring at eight months. Visual acuity was 0.05 in right eye and 0.8 in left. Case 2, a 32 year-old woman with Graves' disease diagnosed during pregnancy and DON occurring at five months. Visual acuity was 0.2 in right eye and 0.09 in left. In cases 1 and 2, since no permission for therapy during pregnancy was obtained from either patient, systemic steroid therapy was performed after delivery. Case 3, a 31 year-old woman with Graves' disease diagnosed during pregnancy. At nine months, DON was diagnosed in both eyes. Visual acuity was 0.07 in right eye and 0.2 in left. An organized systemic steroid therapy following delivery at the end of a normal gestational period was performed. In all three patients, higher levels of thyroid antibodies were observed while thyroid function remained controlled.
  
  
  CONCLUSIONS
  DON developed in pregnant woman with Graves' disease who have higher levels of thyroid antibodies. A close coordination between internists and obstetricians is required for appropriate treatment, including systemic steroid therapy.
