Graves' eye disease can also be present when the level of thyroid hormone in the blood is normal or low, depending on the degree of glandular stimulation caused by the immune attack and by the amount of thyroid gland destruction present at the time of diagnosis.owever, most patients with eye symptoms have abnormal hormone levels that are accompanied by specific antibodies in the blood stream. The components of the disease affecting the thyroid gland and the eyes have common causes, but evolve separately and must each be treated separately.
