However, in the case of TED, different antibodies attack the muscles associated with eye and eyelid movement. The eye version of this disease is called Thyroid Eye Disease. This often causes the thyroid gland to become over active. In the case of Graves' disease, the body sees the thyroid gland as the foreign object and produces antibodies that attack the thyroid gland. Autoimmune disease may be understood as a process by which the body sees some part of itself as being foreign and reacts to it much the same way that it would to any bacteria or virus. This disease is caused by what is described as an autoimmune process.


TED is usually associated with systemic (generalized) hyperthyroidism or Graves' disease. A great deal can be done to improve these conditions with medical treatment, although some patients will need surgery to help ease their issues. Some patients are left with permanent changes, and in others the eyes return to normal. Once stabilized, it is unusual for the eyes to start changing again. It is important to realize that if one of these occurs, it does not mean you will necessarily get all the other symptoms too.Įye problems will usually occur and frequently change in type or severity for between six months and two years. These include redness and swelling, double vision, decreased vision, eyelid retraction (inability to close the eyes), and a bulging of the eye itself. Thyroid disease can cause multiple eye problems. It also rarely occurs in those who are hypothyroid and even when there is an absence of thyroid abnormalities in the body. Although TED is seen in all types of thyroid disorders, it is most common in patients that are or were hyperthyroid. Your doctor may also use the term Thyroid Associated Orbitopathy (TAO). The eye changes associated with thyroid disease are referred to as Thyroid Eye Disease (TED).
