Can thyroid problems cause eye problems?
In some people, an eye problem known as Graves’ ophthalmopathy may develop if hypothyroidism develops after treatment for Graves’ disease — the most common form of overactive thyroid (hyperthyroidism). Graves’ ophthalmopathy can cause eye discomfort, protruding eyeballs and vision changes.
What is thyroid associated ophthalmopathy?
Thyroid-associated orbitopathy (TAO), frequently termed Graves ophthalmopathy, is part of an autoimmune process that can affect the orbital and periorbital tissue, the thyroid gland, and, rarely, the pretibial skin or digits (thyroid acropachy).
How does Hashimoto’s affect the eyes?
Similarly, hypothyroidism may cause dry eyes. A study comparing people with Hashimoto’s disease to people with a healthy thyroid found that those with Hashimoto’s are more likely to have dry eyes. This result is because the tear duct of the eye is a target organ of thyroid hormones.
Can thyroid problems cause optic nerve damage?
In more advanced thyroid eye disease, there may also be: Blurred or loss of vision due to optic nerve compression or corneal damage.
How is Graves ophthalmopathy diagnosed?
HOW IS THE DIAGNOSIS MADE? If you have already been diagnosed with hyperthyroidism, a doctor may diagnose Graves’ eye disease by examining your eyes and finding swelling and enlargement of the eye muscles. A computed tomography (CT) scan or magnetic resonance imaging (MRI) scan of the eye muscles may be helpful.
Why is there ophthalmopathy in graves?
Graves’ ophthalmopathy results from a buildup of certain carbohydrates in the muscles and tissues behind the eyes — the cause of which also isn’t known. It appears that the same antibody that can cause thyroid dysfunction may also have an “attraction” to tissues surrounding the eyes.
Can thyroid problems cause blurry vision?
Patients with hypothyroidism may also report aches and pains, swelling in the legs, and difficulty concentrating. Menstrual dysfunction, hair loss, decreased sweating, decreased appetite, mood changes, blurred vision, and hearing impairment are also possible symptoms.
Can thyroid problems cause eye pressure?
For example, hypothyroidism (an underactive thyroid) can help to increase chemical deposits in the group of vessels that bring blood to and from the eye. This can lead to an increase in pressure within the eyeball, which is a main symptom of glaucoma.
Does Graves ophthalmopathy go away?
Graves’ eye disease often improves on its own. However, in some patients symptoms may persist despite treatment of the overactive thyroid gland and specific eye therapies.
Is Graves ophthalmopathy curable?
Graves’ ophthalmopathy doesn’t always improve with treatment of Graves’ disease. Symptoms of Graves’ ophthalmopathy may even get worse for three to six months. After that, the signs and symptoms of Graves’ ophthalmopathy usually become stable for a year or so and then begin to get better, often on their own.
Why is there lid lag in thyrotoxicosis?
Both lid lag and lid retraction are attributed in part to the sympathetic hyperactivity of hyperthyroidism, which causes excess contraction of the Müller muscle (the involuntary lid elevator whose paralysis causes the ptosis of Horner syndrome).
