Thyroid Eye Disease is an autoimmune eye condition that, while separate from thyroid disease, is often seen in conjunction with Graves' Disease. The condition may also be seen in people with no other evidence of thyroid dysfunction, and occasionally in patients who have Hashimoto's Disease. Most thyroid patients, however, will not develop thyroid eye disease, and if so, only mildly so.
Some of the symptoms are:
Pain in the eyes, itching, itching, dry eyes
Inflammation and swelling of the eye, and its surrounding tissues
Swelling in the orbital tissues which causes the eye to be pushed forward -- referred to as exophthalmos -- which can make Thyroid Eye Disease sufferers appear to have a wide-eyed or bulging stare.
Bloodshot appearance to eyes
Double vision
Impaired vision
