Baptist Eye Surgeons • March 8, 2023

Thyroid eye disease is a rare but serious condition that can have long-lasting effects on your vision. Mostclose-up of a caucasian man's right eye suffering from thyroid eye diseasecommonly known for causing bulging eyes, it can also gradually damage your optic nerve which can lead to glaucoma. You will need a medical diagnosis and professional treatment in order to avoid these serious complications.

Thyroid eye disease is an autoimmune disease usually caused by a problem with the thyroid, often due to overactivity. It results in the inflammation and swelling of tissues around the eye. Common symptoms include bulging eyes, double vision, and pain. It is diagnosed with a comprehensive eye exam and can be treated in a number of ways.

What Is Thyroid Eye Disease?

Also known as Graves ophthalmopathy , thyroid eye disease (TED or Graves orbitopathy ) is an autoimmune disorder affecting the eyes and the tissues around the eye. It’s usually caused by an overactive thyroid gland ( hyperthyroidism ). However, it can also affect people with normal thyroid function or an underactive thyroid ( hypothyroidism ). 

Causes

Thyroid eye disease occurs when the immune system attacks the eyes’ surrounding tissue. This results in the swelling and inflammation of tissues such as:

  • Muscles
  • Connective tissue
  • Fatty tissue 

As an autoimmune disease, thyroid eye disease is due to the immune system attacking the body. In this case, it attacks the eyes and eyelids as well as other surrounding tissues. 

Phases

The condition has two different phases:

  • Active
  • Stable

The active phase is also known as the inflammatory phase . This phase can last from just a few months to as long as three years. The stable phase occurs when the inflammation has subsided. 

Connection to Graves Disease

Thyroid eye disease is often related to another autoimmune disorder known as Graves disease .

It can also affect the:

  • Thyroid
  • Eyes
  • Skin

Graves disease can lead to hyperthyroidism which is when your body releases too many thyroid hormones. However, it can occasionally lead to the opposite problem of hyperthyroidism. Both instances, as well as people with normal thyroid hormone levels, can experience thyroid eye disease.

Symptoms

Symptoms of thyroid eye disease can vary. On the other hand, there are certain signs you and your Knoxville ophthalmologist can be on the lookout for.

They include:

  • Bulging eyes ( proptosis )
  • Eyes feeling gritty
  • Redness
  • Double vision ( diplopia )
  • Pain behind your eyes
  • Pain when you move your eyes
  • Dry eyes
  • Increased tear production

Both eyes will have symptoms in the majority of cases, although there are instances where only one eye is affected. Contact your Knoxville eye doctor immediately if you experience any changes in your vision or the skin around your eyes. They will be able to diagnose the issue and provide the necessary treatment for your condition.

Possible Complications

Loss of vision can occur in severe cases of the disease due to optic nerve damage. In the case of thyroid eye disease, pressure on the optic nerve can be caused by buildup in vessels that transport blood through the eye. 

This only highlights how important it is to seek treatment immediately if you notice changes in your eyes or vision. While the changes caused by thyroid eye disease may not seem that severe in the beginning, lack of treatment can lead to irreversible vision loss. Contact our office immediately if you notice any sudden changes to your vision so you can get the treatment you need.

You’ll need a comprehensive eye exam and possibly other tests to be diagnosed with thyroid eye disease. While you’ll need treatment for thyroid disease, this won’t cure thyroid eye disease. Your Knoxville ophthalmologist will prescribe one or more treatments based on your individual needs.

Diagnosis

Your eye doctor will perform a comprehensive eye exam to see if you have thyroid eye disease or not. These exams use eye dilation, which allows eyecare professionals to view the inner structure of your eyes. This gives them insight not only into your eye health but overall health as well.

Other necessary tests that may be required include: 

  • An ultrasound of the eyes
  • Computed tomography (CT scan)
  • Magnetic resonance imaging (MRI)

Treatment

Treatment for thyroid eye disease can vary depending on the patient. In some cases, you may be prescribed more than one treatment to fight the disease. This may include:

  • Over-the-counter medications (OTCs)
  • Prescription medications
  • Lifestyle changes 
  • At-home treatments
  • Surgery
  • Radiation

OTCs in the form of eye drops and artificial tears can help relieve irritation and dryness without a prescription. Prescription medications such as anti-inflammatory medicines and systemic steroids may be prescribed to treat the condition. Be sure to follow your doctor’s instructions and discuss any possible side effects beforehand. 

Lifestyle changes like quitting smoking can make a big impact on your symptoms. At-home treatments can also help alleviate your symptoms. To make yourself feel more comfortable, try:

  • Applying a cold compress to your eyes
  • Raising your head above your body when lying down
  • Using an eye patch to reduce double vision
  • Wearing sunglasses

Surgery may be necessary for some patients. This could involve loosening the eyelids to protect the cornea, moving your eye muscles, enlarging the eye socket, or removing excess tissue. Radiation may be used in the form of radioactive iodine to get rid of the hormone-producing cells.

Night vision problems can make everyday activities like driving at dusk, walking in poorly lit places, or adjusting to indoor lighting harder and sometimes unsafe. Trouble seeing in low light, called nyctalopia, is not a disease itself but a sign that something else may be affecting your eyes. Learning what causes night vision problems and when to get help is important for keeping your vision healthy. What Are Night Vision Problems? Night vision problems mean it is hard to see clearly in low light or darkness. Some people notice their eyes take longer to adjust when going from bright to dim places. Others may have trouble with glare from headlights, seeing less contrast, or things just looking dimmer at night. Mild changes in night vision can happen as you get older, but if your symptoms keep getting worse or do not go away, you should pay attention to them. Common Causes of Night Vision Difficulties There are several potential causes of night vision problems. Night vision problems can have many causes, from getting older to certain eye conditions, such as lens problems, leading to blurred vision and increased sensitivity to glare. They are one of the most common causes of poor night vision, especially in older adults. 1. Cataracts Cataracts cause clouding of the eye’s natural lens, leading to blurred vision and increased sensitivity to glare. They are one of the most common causes of poor night vision, especially in older adults. 2. Vitamin A Deficiency Vitamin A is important for keeping your retina healthy. If you do not get enough vitamin A, your eyes may have trouble adjusting to darkness, which can lead to night blindness. 3. Glaucoma Some types of glaucoma can affect your side vision and make it harder to see differences between light and dark. As the optic nerve gets damaged, seeing in low light can become more difficult. 4. Retinitis Pigmentosa This inherited eye condition slowly affects your ability to see at night and to the sides. Early signs often include trouble seeing in the dark. 5. Diabetes-Related Eye Disease Diabetic retinopathy can harm the blood vessels in your retina, which may cause blurry vision and make it harder to see at night. 6. Aging and Pupil Changes As people get older, their pupils do not react to light changes as quickly, and the retina becomes less sensitive. This naturally makes night vision worse over time. Symptoms to Watch For Night vision problems often develop slowly. Some common signs are: Difficulty seeing in low light or darkness Trouble driving at night due to glare from headlights Longer adjustment time when moving between light and dark environments Reduced contrast or clarity in dim settings Frequent squinting or eye strain in low light If these symptoms start to affect your daily life, it is a good idea to get a full eye check-up. When to See an Eye Doctor You should see an eye doctor if you notice new night vision problems, if they are getting worse, or if you have other changes in your vision. The doctor can run tests to find out what is causing the problem and suggest the right treatment. A full eye exam might include checking your retina, testing your field of vision, and taking images to look at your eye health. Finding problems early is very important for conditions like glaucoma, diabetic eye disease, and retinal disorders, because early treatment can help protect your vision. Protecting Your Night Vision Not all causes of night vision loss can be prevented, but taking care of your eyes can lower your risk and help you see better. Some helpful steps are: Scheduling regular eye exams Handling chronic health conditions like diabetes Eating a diet rich in vitamin A and antioxidants Wearing proper corrective lenses if prescribed Avoiding driving with untreated vision changes Prioritizing Your Eye Health Night vision problems can be an early sign of eye disease. Since many eye problems develop slowly, having regular eye exams is one of the best ways to catch changes early and keep your vision healthy for the long term. If you have trouble seeing at night or notice any changes in your vision, making an appointment for an eye exam can help keep your eyes healthy and your vision clear in all types of light.
