What are the symptoms of thyroid eye disease (TED) or Graves’ disease?

Symptoms of TED (or Graves' disease) can vary and come and go. Here are some of them:

Bulging eyes. EOT can cause the muscles in and around the eye to swell and push the eyes outward. Because of this bulging of the eye, it looks like people are staring all the time.

Eyelid retraction. When the eye is pushed forward, the upper and lower eyelids retract (move backward). This makes the white parts of the eye more visible.

Dry eyes. With EOT, the eyes become more exposed to wind and dust. This can make the eyes very dry. The dry eye problem causes the eyes to feel scratchy and irritable, and blurred vision. Excessive sensitivity to light is also a problem.

Vision changes. Muscle swelling can cause double vision (seeing two images of the same object). Swelling can also press on and damage the optic nerve (the part of the eye that connects the eye to the brain), which can cause vision loss.

"Bags" in the eyes. Eyelid swelling can cause the tissue surrounding the eye to bulge. This is seen as bags around the eyes and can make a person look older than he or she is.
