Eyes that stick out generally indicate expressions of shock, gasp, or even anger. However, if your eyes stick out at any time, you should immediately consult a doctor. Exophthalmos, or proptosis, is a medical term that is often used to describe the bulging eyeball. This disorder is common in people who have thyroid disease, specifically Graves' disease. What is Graves' disease, and why does it cause the eyes to protrude? What's the danger? Check out the complete information in this article
What is Graves' disease?
Graves' disease is a disorder of the immune system that causes the thyroid gland to become aggressive. The function of the thyroid gland itself is to produce thyroid hormones to control body activities. If the thyroid gland is overactive and produces more thyroid hormone, it will cause hyperthyroidism.
Graves' disease affects 1 in 3 people in the world, and is more common in women aged 30-50 years or people who smoke. People who have immune disorders such as type 1 diabetes or rheumatoid arthritis (rheumatism) are also more likely to develop this disease
Why can Graves' disease cause the eyes to stick out?
Graves' disease is an autoimmune disease, a condition in which the body's immune system turns to attack healthy tissue (instead of foreign disease-causing cells such as viruses or bacteria). In this case, the immune system attacks the thyroid gland located in the neck and the muscle and fatty tissue around the eyes, causing swelling of the eyes.
The inflammatory effect caused by this attack can then increase the pressure on the eyeball. In some patients, this can compress the nerves of the eye. The swelling and inflammation that occurs also weakens the function of the eye muscles called extraocular muscles.
Some of the symptoms that people with Graves' disease have, other than bulging eyes, include:
- Eye pain
- Dry eyes
- Irritated eyes
- Photophobia or sensitive to light
- Frequent tears
- Diplopia or double vision caused by weakened eye muscles
- Blurred vision
- Blindness, when the nerve of the eye is pinched
- It is difficult to move the eyes, because the eye muscles are affected
- Feeling the pressure behind the eyeball
Bulging eyes due to Graves' disease can cause long-term vision problems. Even so, the effects rarely persist if the condition is treated promptly.
How do doctors diagnose this condition?
First of all, an ophthalmologist will examine the ability of your eyes to move. Then the doctor will measure how far your eyeball protrudes from where it should be with a device called an exophthalmometer. The eye can be called abnormally protruding outward if the length of the protrusion is more than 2 mm from the upper normal limit.
How can this eye condition be treated?
There are several treatments that can be done to treat bulging eyes due to Graves' disease, such as:
- Quit smoking to reduce the risk factors
- Take medication to lower the level of thyroid hormone in the blood. These medications don't directly treat your eye problems, but they can prevent them from getting worse
- Artificial tears lubricate dry eyes
- Using sunglasses for photophobia
- Corticosteroid injections can help lower the inflammation that accompanies your condition
- Surgical action
The cause of the bulging eyes, apart from Graves' disease
Bulging eyes can also occur due to other conditions besides Graves' disease, namely:
- Eye injury
- Bleeding behind the eye
- Abnormal blood vessels at the back of the eye
- Infection of the eye tissue
- Eye cancer, such as neuroblastoma and sarcoma
