- Is Your Thyroid Condition Affecting Your Eyes?
Many people with an over active thyroid gland caused by Graves’ disease develop what is known as eye signs (Graves’ ophthalmopathy). Early symptoms can include redness, dryness, itching, a gritty feeling, swelling of the eyelids and an inability to wear contact lenses. Symptoms can be especially bad at night, in air conditioned buildings and during windy days.
The eyes appear to be slightly bulging because of spasms of the muscles of the lids, giving them a staring appearance. Around half of people with Graves’ disease only experience relatively mild symptoms, but another half develops more severe eye disease.
The more severe version of thyroid eye disease is an autoimmune disease of the eye socket and eye muscles in which there is inflammation, swelling and eventual scarring. The immune system attacks the eyes and surrounding muscles. It occurs most often in people with Graves’ disease but can also occur in people with Hashimoto’s thyroiditis and thyroid cancer.
There are two phases of thyroid eye disease:
In either phase the eyes can feel irritated, like there is something inside them and the vision can be blurry.
The irritation can be relieved by lubricating eye drops. Redness and aching can be relieved by the use of a cold compress over the eyes; this is available from pharmacies. Since symptoms tend to be worse at night, some people find that elevating the head of the bed with a brick can give some symptom relief.
During phase one when there is a lot of inflammation and swelling, oral steroids like prednisone are often given. This can reduce the swelling and pain. Steroids cannot be used for long periods of time because they have side effects, such as weight gain, indigestion and a worsening of restlessness, which is also a symptom of Graves’ disease. Some people require radiotherapy if the swelling is very bad.
During phase two when there is scarring, some people need surgery to lower the upper eyelid if it is abnormally raised. Surgery can reduce the “poppyness” of the eyes and also can fix the double vision if the eye muscles are moved.
Thyroid eye disease is most common in people with an overactive thyroid gland caused by Graves’ disease. The Graves’ disease is quickly treated by reducing thyroid hormone levels but unfortunately this doesn’t help the eye disease much. For many people, thyroid eye disease becomes a long term problem; the inflammation and swelling pass but around a third of people are left with continual dryness, irritation and sensitivity.
Thyroid eye disease is an autoimmune disease and it must be supported like all autoimmune diseases: a change in diet, supporting the digestion, liver and immune system.
