Thyroid eye disease (TED) is an autoimmune condition where the immune system mistakenly attacks the tissues around the eyes, causing inflammation and swelling. This can lead to symptoms such as bulging eyes, double vision, discomfort, and in severe cases, vision loss.

TED is often associated with thyroid disorders like Graves' disease and can significantly impact a person's quality of life. Early diagnosis and treatment are crucial to manage symptoms and prevent complications. Advances in therapy are providing new hope for those affected, helping to protect vision and improve eye appearance.
