Abstract
30 patients with Graves' ophthalmopathy were subjected to exophthalmometry in the upright and supine positions to determine if the difference in exophthalmometer readings in these two situations are significantly different and would help in distinguishing the early and late Graves' ophthalmopathy patients. The cases were divided into two groups (of 15 patients each) of early Graves' ophthalmopathy (Grades 0,1,2) and late Graves' ophthalmopathy (Grades 3,4,5) according to the American Thyroid Association classification. In addition, 15 age and sex matched normal individuals who served as controls, also underwent similar investigation. Contrary to earlier observations, the results showed statistically insignificant increase in exophthalmometer readings when going from the erect to the supine position. It was concluded that postural change in exophthalmometer readings neither helps in distinguishing normal subjects from patients of Graves' ophthalmopathy nor can it differentiate between various grades of Graves ophthalmopathy.
