Thyroid Eye Disease


(Also Known as Graves’ Ophthalmopathy or Graves’ Orbitopathy)


Thyroid eye disease (abbreviated as TED) is an autoimmune disease that affects some people with autoimmune thyroid disease. TED is most common in people with hyperthyroidism due to Graves’ disease and rarely, may occur in patients with normal or low thyroid levels.

  • About one in every three people with Graves’ disease develop eye symptoms.
  • While eye symptoms can occur at any time, they usually appear within the first year of diagnosis of Graves’ disease.
  • TED is usually mild and gets better on its own over time.
  • Some cases can be quite severe and can require medications or surgery.

    Symptoms of thyroid eye disease include:

    • Feeling of grittiness in your eyes (like “sand in your eyes”) and sensitivity to light
    • Pain behind your eyes or with eye movement
    • Redness of the eyes due to swelling/irritation of the thin coating (conjunctiva) that covers the white part of the eyes
    • Dry eyes
    • Extra tearing of the eyes
    • Puffy or red eyelids
    • Forward bulging of your eyes (proptosis)
    • Seeing double (Double vision)


    If you notice any of these symptoms of more serious eye disease, contact your doctor immediately.

    • If your eyelids cannot close fully due to TED, the outer surface of your eyeball can be injured.
    • If you notice a change in how you see colors
    • If parts of your field of vision are lost (this can happen if your optic nerve is compressed.)

    Thyroid Eye Disease FAQs


    Your thyroid gland is a butterfly-shaped gland that is located in the lower front of your neck. The job of your thyroid gland is to make thyroid hormones. Thyroid hormones are released into your blood and carried to every tissue in your body. Thyroid hormones help your body use energy, stay warm and keep your brain, heart, muscles, and other organs working normally.


    The diagnosis of thyroid eye disease (TED) can be made by your primary care physician, your thyroid doctor/ endocrinologist, or your eye doctor (ophthalmologist). This usually occurs when you tell them about your symptoms, and they examine your eyes. You may also need additional testing such as

    • Measurement of the amount of bulging of your eye
    • Tests to check your visual field, and color vision
    • A computed tomography (CT) scan or magnetic resonance imaging (MRI) scan of your eye sockets and eye muscles


    If the symptoms and/or eye changes from TED are moderate-to-severe or if the diagnosis or severity is uncertain, you should be referred to an ophthalmologist (eye doctor).


    More research on TED is needed to better understand why some people get it and others do not. However, research has identified some factors that can make it more likely for TED to develop or get worse.

    • Exposure to cigarette smoke, even secondhand smoke
      • If you smoke, you should try to quit.
      • You should avoid all cigarette smoke including secondhand smoke
      • Having abnormal thyroid hormone levels (high or low) can make your eye disease worse. You can work with your doctor to keep your thyroid hormone levels in the normal range.
    • Treatment of your overactive thyroid with radioactive iodine (RAI), especially in people who also smoke and/ or people who already have TED.
      • Your doctor will usually suggest you avoid treatment with RAI if you have moderate or severe eye symptoms.
      • However, if RAI is the best treatment for you, your doctor may discuss giving you a steroid medicine at the time of the RAI treatment. This can prevent your eye disease from getting worse.


    If you have TED, there is good treatment available. There are some non-medication treatments you can use yourself, other treatments should be recommended or prescribed by your doctor, and sometimes surgery is needed.

    Non-medication treatments you can use:

    • Wear sunglasses if your eyes are more sensitive to sunlight. Wearing sunglasses helps protect your eyes from both sun and wind. Sunglasses with a wraparound design offer the best protection.
    • Use lubricating eyedrops. Eyedrops, such as artificial tears, may help relieve dryness and scratchiness. Be sure to use eyedrops that are for lubrication. Check with your doctor if you aren’t sure what type of eyedrops to use.
      • A lubricating gel can be used before bed if your eyelids do not close completely. This will prevent your cornea (the outer layer of your eye) from drying out while you are sleeping.
    • Raise the head of your bed. Keeping your head higher than the rest of your body may relieve pressure on your eyes. This can help reduce swelling and puffiness.
    • Prisms. If double vision is a problem, glasses containing prisms may be prescribed by your eye doctor.


    Your doctor may recommend a medication. You and your doctor should review all possible side effects and the potential benefits before considering a medicine. Newer medicines are being investigated to see if they will help TED.

    • Surgery is required in only a small number of patients with TED.
    • Usually, surgery is planned when your eye symptoms have reached the inactive phase. Inactive means that your eye symptoms are stable. They are not getting worse or better.
    • Very rarely, emergency surgery is needed if you have any vision loss.
    • You may need more than one type of eye surgery. If so, your ophthalmologist will let you know the best timing and order for the different procedures.
    • Several types of ophthalmologists may be needed. All TED surgeries should be done at a medical center that specializes in the type of surgery you need.


    If your eyesight is in danger and/or you have significant eye bulging, a type of surgery called orbital decompression can be done.

    • In this procedure, bone in the wall of your eye socket (orbit) is removed. Also, fat can be removed from the eye socket to allow more space for the swollen tissues.
    • This procedure provides room for your eyes to return to their normal position. It can also improve your vision if there is compression of the optic nerve.
    • There is a risk of complications. This can include double vision.
      • If you have double vision before the surgery, it may still be a problem after the surgery.
      • You might develop new double vision after surgery.
    • Most of the time this type of surgery is not scheduled until the inactive phase of your symptoms is reached. However, emergency orbital decompression can be done if compression of the optic nerve is reducing your vision and you have not responded to medical therapy such as steroids.


    Sometimes scar tissue and other changes in your eyes can cause one or more eye muscles to be too short or too tight. This pulls your eyes out of alignment, leading to double vision.

    • Eye muscle surgery may help correct double vision. The affected muscle is detached from your eyeball and reattached so that your eyes move together.

    In some cases, you may need more than one operation to improve double vision.


    Eyelids can be retracted, leaving your eyes more widely open. This can cause you to have difficulty closing your eyelids. This leaves your eyeballs more exposed, causing excessive tear production and irritation.

    • Surgical repositioning of your eyelid may help reduce the irritation.
