Thyroid Eye Disease Symptoms and Signs

Thyroid Eye Disease (TED) is an ongoing condition that can get worse over time if it is left untreated. Treating Thyroid Eye Disease early can help you avoid serious eye damage.

Use the TED Symptom Simulator Tool below to learn about the symptoms of TED and how they progress or read the list of symptoms below.

The TED Symptom Survey can help you identify symptoms of TED so you can share them with your doctor.


Symptoms of Thyroid Eye Disease (TED)

The longer TED goes untreated, the more likely serious eye damage will occur.

That’s why it’s so important to regularly check for Thyroid Eye Disease symptoms. The sooner you spot symptoms, like those listed below, the sooner you and your doctor can come up with a treatment plan.

Red eyes

Your eyes and eyelids may look red or bloodshot. At first, these changes may be confused with allergies or an infection. Your doctor may refer to these changes as erythema (er-uh-thee-muh).

Eye pain and pressure icon Eye pain and pressure icon Eye pain and pressure icon

Eye pain and eye pressure

You may feel pain in, around, or behind your eye; including pain when looking up, down, or sideways.

You may even feel pressure behind or around your eye. This pressure may also give you headaches.

In one study, about 30 out of 100 people (30%) with TED had eye pain.

Light sensitivity icon Light sensitivity icon Light sensitivity icon

Sensitivity to light

Your eyes may become extra sensitive to light. This means that you may find sunlight or bright indoor light to be uncomfortable or even painful. Your doctor may refer to this change as photophobia (fow-tow-fow-bee-uh).

Blurred vision icon Blurred vision icon Blurred vision icon

Blurry vision

Images may look blurry or out of focus.

In one study, about 30 out of 100 people (30%) with TED had blurry vision.

Double vision icon Double vision icon Double vision icon

Double vision

You may see 2 images of the same object. Your doctor may refer to this change as diplopia (dih-ploh-pee-uh).

In one clinical study, about 50 out of 100 people (50%) with TED had double vision.

Bulging eyes icon Bulging eyes icon Bulging eyes icon

Bulging eyes

Because of the swelling of the fat and muscle tissue behind your eyes, they may bulge forward. This can happen to just one eye or both eyes. Your doctor may call this change proptosis (prop-toe-sis) or exophthalmos (ek-sof-thal-muhs). During an exam, your doctor may measure the amount of eye bulging using a special ruler called an exophthalmometer (ek-sof-thuhl-mom-i-ter).

In one study, about 60 out of 100 people (60%) with TED had bulging eyes.

Eyelid retraction icon Eyelid retraction icon Eyelid retraction icon

Eyelid retraction

Your eyelids look like they’ve been pulled back from where they normally are, and you may find it hard to close your eyes all the way. In some cases, you may not be able to close them at all.

About 90 out of 100 people (90%) with Thyroid Eye Disease (TED) had retracted eyelids (eyelids that don’t close properly).

Swollen eyelid icon Swollen eyelid icon Swollen eyelid icon

Swollen, puffy eyelids

Your eyelids may look puffy and swollen. At first, you or your doctor may think this is because of allergies or an infection. Your doctor may refer to this change as eyelid edema (ih-dee-muh).

Eyes that point in different directions

Looking in the mirror, you may notice that the position of your eyes doesn’t match. Eyes that are not aligned properly may cause other symptoms, such as double vision. Your doctor may refer to misaligned eyes as
strabismus (strah-biz-muss).

Color vision loss icon Color vision loss icon Color vision loss icon

Color vision loss

You may notice colors don’t appear as bright as they used to. Or there’s a difference in how bright colors seem when comparing one eye with the other.

In rare cases, you could become color blind. Losing color vision can mean that your optic nerve is being damaged and that you’re at risk of losing your sight.

Talk to your doctor right away if you notice color vision changes.

About 6 out of 100 people (6%) with Thyroid Eye Disease may notice some color vision loss from damage to the optic nerve.

Vision loss

In some cases, you may notice there are parts of your vision missing, or you can’t see at all. This is because Thyroid Eye Disease (TED) can cause swelling that pushes down on the optic nerve. If this happens, emergency surgery may be needed to save your vision.

“The bulging and movement of the eyeballs was compressing my optic nerves. There was some question as to whether I would go completely blind.”
— Ron, real TED patient

Watch Ron’s story

Up to 6 out of 100 people (6%) with TED may have optic nerve damage.

Optic nerve damage can lead to blindness, but it’s very rare for TED patients to lose all of their vision. Talk to your doctor right away if you notice vision loss.

TED is a rare condition, and not all doctors are used to treating it.
Make sure you see a doctor who is.

Listen To Your Eyes

Hear actual TED patients describe the importance of listening to what their eyes were telling them in this video:

It’s important to remember that TED affects everyone differently

While some symptoms may get better over time, others may not. It’s even possible for symptoms to return, or “flare up.”

According to specialists, being treated as early as possible in the “acute” (or “active”) phase is ideal, but treatment may still be able to help during the “chronic” (or “inactive”) phase.

If you have a thyroid condition (like Graves’) and eye symptoms, talk to a TED Specialist.
