Thyroid eye disease, also known as Graves' eye disease or thyroid-associated ophthalmopathy, is a condition that affects the tissues and muscles around the eyes. It is often linked to a thyroid disorder like Graves' disease, an autoimmune condition that causes hyperthyroidism. Symptoms can range from mild to severe, affecting both the look and function of the eyes. Early detection of thyroid eye disease is crucial for effective treatment. Recognizing these signs allows individuals to seek proper medical care to prevent complications and protect their eye health.
