Risk Factors for Graves' Orbitopathy; the Australian Thyroid-Associated Orbitopathy Research (ATOR) Study

This study identified increase age of onset, duration of GH, and smoking as risk factors for GO. Usage of antithyroid medication was negatively related to GO. Older patients with restricted ocular motility, strabismus, and active GO are at higher risk of DON and may benefit from early medical intervention.
