Can Synthroid Affect Your Vision
Synthroid is one of the most common medications used to treat hypothyroidism. Also known by its generic name levothyroxine, Synthroid contains synthetic thyroid hormone that helps to replace low thyroid hormone in your body.
Like most medications, Synthroid comes with a list of side effects. One of the rarer side effects of Synthroid is that it may cause blurred or double vision and eye pain. These symptoms may stem from swelling caused by taking too much thyroid hormone or an adverse reaction to the medication, like an allergic reaction.
There are very few reports that Synthroid directly causes eye problems, except in rare cases where it is an adverse reaction. If you struggle with eye issues while taking Synthroid, it is more likely related to your thyroid not being correctly managed or other causative factors like allergies, etc.
Thyroid Disease Can Affect Your Eyesight
Abnormalities of the thyroid gland, which is located just below the voice box in the neck, can result in an over- or under-production of thyroid hormone. This hormone regulates your bodys metabolism and energy use. If the thyroid gland stops producing enough hormone to keep the energy levels of the body going, that individual usually feels excessively tired, needs more sleep and often puts on weight since the body doesnt burn enough calories. The thyroid gland also enlarges in an attempt to produce more hormone this is called a goiter. If the gland becomes inflamed, it often overproduces thyroid hormone which causes the affected individual to need a lot less sleep, be very energetic and lose weight due to the extra burning of calories from this increased activity level. This condition of an overactive, inflamed thyroid gland is called Graves disease.
Once the condition burns out, most individuals return to a normal appearance or may have only mild residual changes that cause no further problems. A variety of reconstructive procedures that can restore a more normal eye appearance can be performed by eye surgeons who specialize in eye plastic and reconstructive surgery. Persistent double vision can be corrected by loosening tight eye muscles and giving a greater range of motion. Communicate with your doctor as soon as you have any eye problems. Early diagnosis of thyroid-related eye problems allows for easier correction and control.
Coping With Changes To Your Appearance
It is well known that TED can affect your psychological and social well-being. You may feel anger, loss of self-esteem or confidence, or socially isolated, because of the change in the appearance of your eyes. Your mood can also be affected by medications you may be taking, such as steroids. TED can change your facial appearance and alter your expression which may affect the way people react to you which, understandably, can be difficult to cope with. Treatment, which may include surgery, can often improve this and counselling, or contact with others who have TED, can help you find coping strategies.
Some of the following organisations might be helpful:
- Thyroid Eye Disease Charitable Trust can help put you in touch with other people who have had similar experiences which is often helpful.
- The British Thyroid Foundation has a network of telephone support volunteers that can help. They also have closed Facebook groups for people with TED. You can email them at if you would like their support.
- The charity Changing Faces also offers a support service for anyone experiencing a condition or injury that affects their appearance.

Is There Anything I Can Do
Yes. Here are a few tips:
- We know that one thing that makes this disease worse is smoking. If you smoke, see your GP about getting help to stop. Stopping smoking, even if you already have thyroid eye disease, will reduce the severity.
- Sleeping propped up will help reduce the puffiness around the eyes.
- You may find bright light uncomfortable. Sunglasses will help.
- If you are a driver and experience double vision, let the DVLA know. This is a legal requirement. Usually, they will contact your specialist eye doctor for a report. If the double vision is well controlled with prisms, you may be declared fit to drive. Until then you should not drive.
How Can I Find Support

How Is Thyroid Eye Disease Treated / Managed
Thyroid eye disease in its active phase can last between one and three years. That means if it is left untreated, the inflammation may gradually decrease by itself but may cause damage to vision through the course of the disease. Sometimes, the changes caused by the enlargement of the tissues may not go away. The goal of treatment is to limit inflammation and swelling occurring during the active or inflammatory phase and to protect the front of the eye and prevent vision loss.
Thyroid eye disease is managed by a specialist eye doctor . Any underlying thyroid problems will be managed by your primary care doctor or by a specialist in the hormone systems of the body .
If a thyroid issue is suspected, evaluation and treatment are critical. The first priority is to restore your normal thyroid function. In addition, eye conditions should be examined and treated at the same time as your thyroid gland treatment. Eye problems may continue to progress even after your thyroid function returns to normal.
If you have thyroid eye disease, your eye doctor may recommend one or more of the following treatments to help soothe your eyes and improve your vision:
Cool compresses: Apply cool compresses to your eyes. The extra moisture and cooling effect may provide relief.
Sunglasses: When you have thyroid eye disease, your eyes are more sensitive to sunlight and UV rays. Wearing sunglasses helps protect them from both sun and wind.
How Common Is Thyroid Eye Disease
About one in four patients with Graves disease will have thyroid eye disease. It does not occur with other causes of an overactive thyroid .
Thyroid eye disease is almost five times more common in women than men. However, the disease is often more severe in men. In 90% of people it is associated with an overactive gland, in which case it may be diagnosed before, after, or at the time of diagnosis of Graves disease. In 5% of people it is associated with an underactive thyroid gland and 5% of people affected do not have any thyroid problems. Thyroid eye disease is seven times more likely to occur in smokers.

Treatment Of Thyroid Eye Disease
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 doesnt 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.

Can Lack Of Sleep Cause Thyroid Problems
Sleep habits may play a role in your susceptibility to thyroid disease.

Signs And Symptoms Of Graves’ Eye Disease
In Graves eye disease the tissue around the eye is attacked, and the result is inflammation and swelling, causing:
- Redness and pain
- Dry eye and irritation, occurring when the eyelids cannot close completely over bulging eyes
Progressive swelling may cause:
- Increased pressure inside the eye socket
- Pressure-pain or deep headache, which worsens with eye movements
The muscles around the eye are particularly susceptible to the attack of lymphocytes. As they tighten and lose their ability to stretch, these symptoms can occur:
- The eye is pushed forward in its socket causing a staring appearance
- Restriction of the eyes normal movements, resulting in double vision
As symptoms build, many patients fear they will lose their vision. Fortunately, patients almost never go blind from Graves eye disease.

Thyroid Glands Relation To The Eye
Although Graves disease and Graves eye disease both stem from the immune systems attack on healthy tissue, one disease does not directly cause the other. Thats why treatment of the thyroid gland, while important, does not improve the eye disease. The two diseases run their separate courses and do not necessarily occur at the same time.
Your Thyroid And Your Eyes
The thyroid gland is a small, butterfly-shaped gland that hugs your neck. It produces several hormones that help regulate body temperature, metabolism, heart rate even your digestion process.
Your thyroid gland produces specific amounts of hormones to keep your body healthy and functioning. But sometimes, the gland produces too many hormones or too few .
Vision problems are almost always associated with hyperthyroidism, often with a thyroid-related autoimmune disease called Graves disease. In fact, about a third of people with Graves disease develop Graves ophthalmopathy, a series of eye- and vision-related symptoms associated with their underlying thyroid problem.

What Happens If You Stop Taking Synthroid Abruptly
Discontinuing the use of your Synthroid thyroid medication won’t cause withdrawal symptoms. However, discontinuing the use of your Synthroid thyroid medication may cause you to experience some of the symptoms of hypothyroidism that it is working to treat. This resurgence of symptoms occurs because Synthroid was delivering thyroid hormones to your body, but when you stop the drug, your body no longer receives the necessary hormones.
If you have questions about stopping treatment with Synthroid, we recommend that you first talk with your thyroid doctor.

Heres What You Should Know About Graves Ophthalmopathy:
TED generally develops more commonly in women than in men. It is thought that this is due to a higher incidence of hyperthyroidism in women.
Risk factors include having had radioactive iodine therapy, being middle aged, and smoking cigarettes. Smoking can reduce the effectiveness of medical treatment for Graves.
TED occurs in about half the cases of Graves disease.
When TED is active, the symptoms can last from 6 months to 2 years or more. There may be long inactive periods of time with fewer symptoms as well.
TED has a genetic component, although the underlying mechanism behind the disease is not fully understood.
People with TED may be at relative risk for other autoimmune disorders. These can include rheumatoid arthritis, lupus, vitiligo, Addison’s disease, celiac disease, and more.
