PURPOSE
To determine risk factors for severe Thyroid-Associated Orbitopathy (TAO). METHODS: We retrospectively studied the clinical data of 385 patients of the New York City area diagnosed with TAO from January 1990 to December 2000. We reviewed clinical characteristics and tried to identify several risk factors. The statistical analysis was applied to the collected data. RESULTS: Men more frequently had proptosis, restrictive myopathy, and optic neuropathy than women. Patients older than 50 years presented more frequently with proptosis, restrictive myopathy, and optic neuropathy than younger than 50 years. Patients with a family history of thyroid disease had similar clinical characteristics compare to those without family history. Smokers more often had proptosis, restrictive myopathy, and compressive optic neuropathy than nonsmokers. Patients who had received radioactive iodine (RAI) treatment were older, and were more frequently smokers. If patients were smokers and treated with radioactive iodine treatment, they were more likely to have proptosis, restrictive myopathy, and compressive optic neuropathy than if not treated with radioactive iodine. However, the RAI treatment did not seem to be associated with severe characteristics of TAO in non-smokers. CONCLUSIONS: The risk factors for severe TAO are: male, age older than 50, smoking, treated with RAI in smokers. |
