Abstract
Graves’ disease is an autoimmune disorder characterized by thyroid gland hyperplasia and excessive production of thyroid hormones [1]. Involvement of the eye, also known as Graves’ Ophthalmopathy or Thyroid Eye Disease (TED) is the most common extrathyroidal manifestation of Graves’ disease [2]. TED results from infiltration of the orbital soft tissues with autoreactive T lymphocytes, proliferation of orbital fibroblasts, and increased adipocytes [3]. Clinically recognizable TED has been reported to occur in 25–50% of GD patients, and sight-threatening disease in 3–5% cases in the Western literature [4]. The diagnosis of TED is usually based on obvious clinical findings such as lid retraction and unilateral or bilateral proptosis in a person with systemic thyroid dysfunction [5]. Orbital imaging aids in ruling out the differential diagnosis, to assess disease activity (MRI), and surgical planning prior to orbital decompression [5]. It has been shown that orbital imaging reveals abnormalities in 90% of patients with Graves’ disease [6].
