Thyroid Eye Disease Symptoms

Thyroid Eye Disease (TED) can cause a number of different symptoms. You may notice that some symptoms develop slowly and others appear quickly.

In time, TED can leave you with ongoing symptoms like eye bulging, eye pain, double vision, and pressure behind the eyes. So, it is important to recognize symptoms early and start a treatment plan with your doctor. The sooner you spot changes to your eyes, the sooner your doctor can help.

TEPEZZA is the only medicine to treat Thyroid Eye Disease (TED) at its source, not just the symptoms. Watch a video to see how TEPEZZA treats TED.

Bulging eyes

Although there are many symptoms of TED to look for, the most noticeable is bulging of the eye, which your doctor may call proptosis (prop-toe-sis) or exophthalmos (ek-sof-thal-muhs).

What causes bulging eyes?

With TED, over time muscle and fat tissue behind the eye become swollen. This swelling can push against the back of the eye, causing it to bulge forward.

How are bulging eyes measured?

During an eye exam, your TED Eye Specialist will use a special ruler called an exophthalmometer (ek-sof-thuhl-mom-i-ter) to measure how far the eyes have bulged.

Generally, your TED Eye Specialist will measure eye bulging before, during, and after treatment. This helps them keep track of how much your eyes have improved.
