Graves' ophthalmopathy is a condition that affects the eyes, often associated with Graves' disease, an autoimmune disorder that causes hyperthyroidism. In this condition, the immune system mistakenly attacks the tissues around the eyes, leading to inflammation and swelling. This can result in symptoms like bulging eyes, dryness, and discomfort. The condition can also cause double vision and difficulty closing the eyes completely. While it primarily affects adults, it can occur in anyone with thyroid issues. Treatment options include medications, radiation therapy, or surgery, depending on the severity of the symptoms and the underlying thyroid condition.
