The exception is for patients who are experiencing vision loss: Up to half of patients with optic nerve damage from thyroid eye disease may be able to avoid immediate surgery, or avoid surgery altogether, with a course of intravenous steroids. Treatment is typically given in 10 sessions over two weeks, with a total dose of 20 Gy, which is well below the dose required to cause retinal damage 35 Gy or nerve damage 50 Gy.
Common side effects can include corneal dryness or development of an early cataract. Figure 3. Patient with visual compromise, orbital congestion and pain from thyroid eye disease top. Improvement in cosmetic appearance, as well as vision, orbital congestion and pain after decompression surgery bottom. Biologic therapy, or customized molecular medicines that specifically target the abnormal biochemical pathways in thyroid eye disease, are a promising hope for the future.

These include currently available medicines such as adalimumab Humira , infliximab Remicade and etanercept Enbrel , as well as many medicines yet to be approved. Unfortunately, these drugs are quite expensive, precluding a large-scale randomized trial from being conducted. As such, physicians are left with weak studies that are little more than anecdotes about clinical improvement with these medicines.
Rituximab is a medicine well-described in its use against lymphoma. It targets the immune cells that produce antibodies B-cells , and physicians were initially very hopeful that there would be a clinical effect in patients with TED. Two large, randomized, controlled, concurrent trials were conducted: one in Europe and one in the United States. Tocilizumab Actemra, Genentech is a potent biologic medicine that was initially used for other severe autoimmune diseases such as giant cell arteritis.
The most exciting drug to be developed in recent memory for thyroid eye disease is surely teprotumumab RV Teprotumumab is an antibody directed against IGF-1, the growth factor pathway associated with the thyroid-hormone receptor. Teprotumumab is the only medicine to date proven to reduce overall clinical severity and proptosis, and provide a sustained response.
Now that this trial has been published, the medicine is in the hands of the Food and Drug Administration, where the approval process could take several months or even years. The drug is still available to patients on an out-of-pocket basis if necessary, however, and the manufacturer can provide discounts based on need and disease severity.

Although the majority of cases of anterior uveitis do not generally require the use of immunosuppressants, some cases may need treatment with these type of drugs, which will be discussed later in further detail:.

Overall, biologic medicines and targeted molecular therapy are the wave of the future. More research is needed, but patients with TED live in exciting times, as these new medicines can truly be life changing.
Surgery for TED is often necessary, but is usually delayed until the disease is in its stable phase. The surgical options consist of the following:. Quality of life is often better after surgery, since orbital congestion, pain and dry eye can improve. Surgery to adjust the extraocular muscles and improve double vision is commonly performed.
However, this can be much more complicated than typical strabismus surgery, and needs to be performed by a surgeon who is experienced in thyroid eye disease. This surgery takes between 30 to 60 minutes, can be performed under general or twilight anesthesia, and is done on an outpatient basis.
Surgery to improve eyelid retraction is often the final step in rehabilitation. This step can also be the most temperamental, as the eyelid structures are incredibly minute and unpredictable. However, significant improvement can be achieved Figure 4. Surgery is performed under twilight anesthesia, can take between 30 to 60 minutes, and is done on an outpatient basis. While thyroid eye disease primarily affects the tissues inside the orbit, there are significant changes in the skin and fat in the eyebrows, cheeks, neck and other areas of the face.
These various changes can be addressed with a combination of lasers, fillers, botulinum toxin i. Great care must be taken when undergoing cosmetic surgery in the context of thyroid eye disease: Treating a TED patient like any other cosmetic surgery patient can, at best, lead to a hollow, unnatural look and, at worst, lead to severe corneal exposure and loss of vision or even loss of the eye.
Figure 5. This goal is within reach, since game-changing new medicines that can halt and reverse symptoms of TED are in the pipeline, and the focus has shifted from simply preserving vision to enhancing such things as cosmesis and quality of life. His areas of interest include TED, facial trauma and cosmetic facial and eyelid procedures. N Engl J Med ; Eur Thyroid J ; A long-term follow-up study.

aprea.vvinners.com/10484.php Inflammatory activity can often be managed by drug therapy. However, inadequate medical therapy may permit the development of various complications in the eye that cannot be sufficiently treated pharmacologically. Whereas drug management demands an interdisciplinary approach with well-trained specialists, surgical treatment of ocular complications due to inflammation requires an experienced surgeon.
In this superbly practical new work, internationally renowned experts in the field provide answers to most of the frequently asked questions. Readers will find answers on the spectrum of clinical manifestations of inflammatory complications; the point at which medical therapy is no longer helpful; the absolute, relative indications, and contraindications for defined surgical procedures in this field; and the preferred surgical instruments and machines for these procedures.
