Thyroid eye disease (TED) is a rare, autoimmune disorder affecting the eyes. It is caused by an overactive thyroid and results in inflammation of the muscles and other tissue around the eyes. This often causes the eyes to bulge or move out of their normal position, leading to double vision or blurred vision.

Symptoms of thyroid eye disease can include: Ocular discomfort or dry eyes, swelling of the eyelids, bulging eyes, double vision or blurred vision, feeling of pressure or “heaviness” behind the eyes, and difficulty closing the eyelids. TED can also lead to an enlargement of the muscles around the eyes, known as thyroid orbitopathy, and can cause additional discomfort.

In most cases, TED is treatable. Depending on the severity of the disease, medications such as steroids, calcium channel blockers and antithyroid drugs may be used to reduce the inflammation and prevent further damage. Surgery may also be used in some cases to correct issues caused by the disease, such as double vision.

Early detection is important when it comes to treating this rare disorder. If you experience any of the symptoms of TED, it’s important to see an ophthalmologist right away. They can determine the best course of action for managing the disease and will likely send you for additional tests or scans.

TED is a serious disorder, but its progression can be slowed or even stopped with early treatment. It’s important to be aware of its signs and symptoms and to seek medical attention if you suspect you may be affected. With the right treatments and care, thyroid eye disease can be managed and its adverse effects minimized.
