What is thyroid eye disease?

How is it connected to the thyroid?

TED is often associated with Graves’ disease. The immune processes overlap, but thyroid hormone levels and eye inflammation do not always move together. Some people develop TED when thyroid hormone levels are normal or low.

Keeping thyroid levels in range matters. An eye specialist may still need to assess and treat the eye condition separately.

What changes might I notice?

Some people notice grittiness, tearing, eyelid swelling, or sensitivity to light. Others see changes in eyelid position, eye prominence, or double vision. Similar symptoms can have other causes, so an examination matters.

Explore the signs or use the symptom checklist to organize a conversation.

Does TED stay the same?

TED can have an active inflammatory period followed by a more stable period. Timing varies, and symptoms can still affect daily life after inflammation settles. “Inactive” does not mean every symptom has disappeared.

What can help?

Care may involve eye-surface support, medicines, prisms, or surgery. The approach depends on what is affected and how severely. An eye professional checks for threats to vision and helps plan follow-up.

Ask what you should watch for between visits and whom to contact if symptoms change.
