Thyroid Eye Disease (TED) Specialist in London

In the early phase of thyroid eye disease, there is a greater chance of slowing progression and even reversing some of the changes of TED. Starting treatment early can reduce the risk of long-term or permanent effects. This may include steroid therapy, along with managing key risk factors such as thyroid hormone levels and smoking. 

Ideally, treatment should begin within the first two to six months of symptoms, although it can still be beneficial up to a year or more after onset. In some cases, newer medications may help reverse changes even beyond this period.

Once the disease has stabilised or ‘burnt out’ – usually after one to two years – many of the physical and functional changes can be corrected with surgery.

Most cases of thyroid eye disease are linked to hyperthyroidism, where the thyroid gland becomes overactive and produces too much thyroxine (thyroid hormone). This is often caused by Graves’ disease, an autoimmune condition in which the body produces antibodies that overstimulate the thyroid gland.

These antibodies – known as TSH receptor antibodies – are also thought to play a key role in thyroid eye disease by mistakenly attacking the tissues around the eyes and causing inflammation. Although TED is most commonly associated with an overactive thyroid, some people develop eye symptoms while their thyroid function is still normal. In these cases, hyperthyroidism may develop later, often within the following year.

No. Graves’ disease affects the thyroid gland, while TED affects the tissues around the eyes. Although the two conditions are closely linked, they are separate. Not everyone with Graves’ disease develops TED, and TED can occasionally affect people with typical thyroid function.

TED usually develops over one to three years. The active (inflammatory) phase can last from 6 to 24 months, during which symptoms may worsen. This is followed by an inactive phase, when inflammation settles, but some physical changes may remain. The timeline and severity vary from person to person.

TED cannot be cured, but the symptoms can be managed effectively. Medical treatments are used during the active phase to reduce inflammation, while surgery may be offered during the stable phase to address long-term issues. With the right care, most patients enjoy lasting relief and improved appearance and function.

Not everyone with TED needs surgery. Many people improve with medical treatment alone. Surgery is usually recommended when there are persistent problems such as eye bulging, double vision or eyelid changes that affect appearance, vision or comfort. At London Oculoplastics, we assess each case carefully before making surgical recommendations.

Yes. London Oculoplastics regularly sees patients from Europe, the Middle East and other regions. We can help coordinate appointments, provide supporting documentation and ensure your visit is efficient and well supported.

In rare cases, TED can cause permanent vision loss if the optic nerve becomes compressed or if the eyes are left exposed and dry. However, with timely treatment and monitoring by a specialist, permanent vision damage is uncommon. Early intervention is important to protect your long-term eye health.

Yes. Smoking is a known risk factor for TED and can make the condition more difficult to manage. Quitting smoking is strongly recommended for anyone diagnosed with TED, as it can slow disease progression and improve treatment outcomes.

Teprotumumab is a new targeted therapy used to treat active TED. It works by blocking the pathways that cause inflammation and tissue swelling. Although it is approved in the US (where it is called Tepezza), it is not yet routinely available on the NHS. In the UK, it may be accessed privately or through selected consultant-led referral pathways. At London Oculoplastics, we can advise on eligibility and next steps.

Surgery is generally offered during the inactive phase of the condition, once inflammation has settled. This is usually at least 6 to 12 months after the active phase ends. Operating too early can lead to unpredictable results. We will always advise you on the safest and most effective timing based on your symptoms and goals.
