Close up of thyroid eye disease

Thyroid Eye Disease

Do your eyes appear to be bulging, accompanied by eye pressure and pain? 

You may have thyroid eye disease (TED), an autoimmune condition that attacks the tissues surrounding the eye. 

Our doctors in Merrillville and Hobart, IN, can help with the only FDA-approved medicine for TED, TEPEZZA. 

Experiencing Vision Changes? Contact Us – We're Available 24/7

In advanced cases of TED, vision loss can occur as the inflamed structures at the back of the eye press against the optic nerve. If you're experiencing vision loss, contact us immediately to evaluate your condition.

Symptoms of Thyroid Eye Disease

  • Dry eyes
  • "Gritty" feeling in eyes
  • Watery eyes
  • Red eyes

From the time I walked into the office I was greeted by an upbeat happy and professional staff. All the tests were done thoroughly and quickly and I was put in exam room. I don't think it was even 5 minutes before Dr. Gross came in with his assistant.

Risk Factors


Genetics factor into your chances of developing thyroid eye disease. If you have a family member who's had the condition or another autoimmune disease, you may be at risk of developing thyroid eye disease.


Women are more likely than men to develop thyroid eye disease. This may be because women are more likely to develop hyperthyroidism, which can then cause TED. However, when men do develop TED, the symptoms are often worse. 


Smoking greatly increases your chances of developing TED. Smoking increases your risk of developing the condition by seven to eight times, and if you do develop TED, smoking can cause symptoms in the active phase to last longer. 


Patients with overactive thyroids have a higher chance of developing TED. However, patients with an underactive thyroid or a normal-functioning thyroid can also develop thyroid eye disease.  


TEPEZZA is the first and only FDA-approved medication to treat TED at its source. Rather than treat the symptoms of TED, TEPEZZA treats the autoimmune disease at its core by helping to decrease inflammation behind the eye. In just eight infusions of TEPEZZA every three weeks, patients can overcome TED. After TEPEZZA, patients will not need daily medication to manage their disease.

About 15% of TEPEZZA patients experience recurrence of the disease. In this case, TEPEZZA infusions can be repeated to treat TED a second time.

A Look at the Process of Treating TED With TEPEZZA

TEPEZZA does more than stop symptoms, it stops the cause of TED. 
TEPEZZA does more than stop symptoms, it stops the cause of TED. 


At our Merrillville or Hobart offices, our doctors will perform an eye exam to take a closer look at how your eyes and eyelids are affected. If TED is suspected, we'll order a blood test to check your thyroid hormone and antibody levels. 

TEPEZZA Infusions

TEPEZZA infusions are given to patients during the active phase of the disease, where symptoms are present and worsening. Eight infusions in total are given.

The first two infusions are 90 minutes long, and the following infusions are each an hour long. They are given three weeks apart, and the dosage is determined based on your weight.


Surgery or orbital radiotherapy may be recommended to address the damage formed in the active phase of thyroid eye disease.

Eyelid, eye muscle, or orbital decompression surgery may be recommended to heal the eye after TED. Orbital decompression is performed to lessen the proptosis of the eye.

Side Effects of TEPEZZA

Reactions to TEPEZZA can occur during your first infusion or during the 24 hours after. Our doctors can modify your following infusions to minimize side effects, but if you experience any of the following symptoms, let us know right away: 

  • High blood pressure
  • Fast heartbeat
  • Redness of the face or feeling hot
  • Difficulty breathing
  • Headache
  • Muscle pain

Does Graves' Disease Cause TED?

TED is often conflated with Graves' disease, a condition where the immune system attacks the thyroid. Other names for TED even involve the word "Graves," such as Graves' eye disease or Graves' ophthalmopathy. Though many Graves' disease patients develop TED, the two are different conditions. You can develop TED without having Graves' disease, and you can have Graves' disease without having TED.

Approximately 40% of patients with Graves' disease develop TED.
