Abstract

Patients with Graves' disease were questioned by postal survey about their smoking history. There were significantly more smokers in the group with ophthalmopathy than in the group with Graves' thyrotoxicosis or controls. Patients with severe eye signs smoked significantly more tobacco than did those with less serious signs.
